Agilent L4437A 32-Channel Form A/Form C General Purpose Switch Data Sheet * LXI compliance includes built-in Ethernet connectivity General purpose switch offers highpower signal switching * Fully-featured graphical web interface The Agilent L4437A is a general purpose switch that is LXI Class C compliant. With its small size and Ethernet connectivity, this switch can be placed wherever your application needs it. * 28 Form C channels up to 1 A, 60 W * 4 Form A channels up to 5 A, 150 W * Armature latching relays * Relay counter * Temperature sensor for overheating conditions * Simultaneous channel switching * Software drivers for most common programming environments The L4437A has 32 general purpose switches that can be used to cycle power to products under test, control status lights, and to actuate external power relays and solenoids. 28 channels are Form C switches for basic switching needs. Four additional Form A channels are offered for highpower switching needs. Using this LXI instrument, you'll get all the benefits of an Ethernet connection, instrument web server, standard software drivers and more. The LXI standard is supported by multiple vendors, enabling lower cost of test with accelerated test integration and development. Versatile switching for your highpower switching needs The L4437A general purpose switch can be used to route signals or to control other system devices. This switch is ideal for device actuation and switching loads or power supplies. The L4437A switch has 28 independent single-pole, double-throw (SPDT) 1 A relays and 4 single-pole, single-throw (Form A) 5 A relays. The 28 Form C channels have 300V, 1 A contacts and can handle up to 60 W. The form A channels are 30 VDC/250 VAC, 5 A contacts and can handle up to 150W, enough for many power line-switching applications. These switches are made of latching armature relays where multiple channels can be closed at the same time. Additionally, for switching reactive loads, the optional terminal blocks have pads for snubbing circuits. The sequence feature defines switch closures and controls and can be used to easily change between different switch setups. Assign a sequence, give it a name and then execute it with the custom name you created. External trigger capabilities make it easy for you to time and synchronize switch closures and openings.

L4437A 32-Ch General Purpose Switch. The L4437A also includes a relay counter to monitor and help predict when relays are nearing their end of life. System connections you can trust The L4437A comes with 2 heavy duty 50-pin Dsub connectors that allow for simple, reliable connection options. Each connector uses 30 micro-inches of gold to ensure a repeatable, accurate measurement. Other connection options include: * Detachable terminal blocks with strain relief * Low-cost, standard 50-pin Dsub connector kits and cables * Mass interconnect solutions 2 Ethernet connectivity enables simple connection to the network and remote access to measurements The Ethernet interface offers highspeed connections, enabling remote access and control. You can set up a private network to filter out unwanted LAN traffic and speed up the I/O throughput, or take advantage of the remote capabilities and distribute your tests worldwide. Monitor, troubleshoot, or debug your application remotely. Ethernet communication also can be used with the support of LAN sockets connections. Figure 2. The Web interface makes it easy to set up, troubleshoot and monitor your test remotely. The optional GPIB interface has many years of proven reliability and can be used for easy integration into existing applications. The L4437A ships with the Agilent E2094N I/O Libraries Suite, which enables connections for Agilent and non-Agilent modular and traditional instruments. This makes it easy for you to configure and integrate instruments into your system. web interface, you can set up, troubleshoot, and monitor your instrument from remote locations. * View and modify instrument setup * Open or close switches * Send, receive or view SCPI commands * Define and execute switch sequences Fully-featured graphical web interface makes it easy to set up and troubleshoot your tests from anywhere in the world * View error queue The built-in web interface provides remote access and control of the instrument via a Java-enabled browser such as Internet Explorer. Using the Additionally, since the web interface is built into the instrument, you can access it on any operating system that supports a web browser without having * Get status reports on relay counts, firmware revisions, and more to install special software. Password protection and LAN lockout are also provided to limit access for additional security. Software for most popular programming environments Full support for standard programming environments ensures compatibility and efficiency. You can use direct I/O with your own software, or use standard IVI and LabVIEW software drivers that provide compatibility with the most popular development environments: * Agilent T&M Toolkit for Microsoft Visual Studio.NET and Agilent VEE Pro * National Instruments LabVIEW, LabWindows/CVI, TestStand, and Switch Manager * Microsoft C/C++ and Visual Basic 3 High-performance switching wherever your application needs it Power button Status LEDs Easy connection options with terminal blocks, standard 50-pin cables or connector kits Optional GPIB External trigger to synchronize events 4 Built-in Ethernet Product specifications Specifications and characteristics Channels/configurations 28 form C 4 form A Switch type Armature latching Input characteristics (per channel) Max volts (DC, AC RMS) 1 Form C, 300 V Form A, 30 VDC/250 VAC Max current (DC, AC RMS) Form C, 1 A switch (2 A carry) Form A, 5 A switch (8 A carry) Power (W, VA) 2 Form C, 60 W Form A, 150 W Volt-Hertz limit 10 8 Offset voltage < 3 uV Initial closed channel resistance Form C, 125 m Form A, 50 m DC isolation (ch-ch, ch-earth) >10 G General specifications AC characteristics Bandwidth at terminal block 3 Crosstalk at terminal block (ch-ch) Capacitance at terminal block 3 10 MHz 100 kHz 1 MHz 10 MHz 55 dB 35 dB 15 dB Ch-Ch Ch-earth Form C, 12 pF/Form A 10 pF75 pF Form C, 21 pF/Form A 19 pF General characteristics Relay life typical Form C, 100 M/100 k Form A, 50 M/30 k Open / close time, typical Form C, 4 ms/4 ms Form A, 10 ms/10 ms Initial/reset relay state Form C, maintains state Form A, user configurable Analog bus connection No 1 DC or AC RMS voltage, channel-to-channel or channel-to-earth 2 Limited to 6 W of channel resistance power loss 3 50 Ohm source, 50 Ohm load, differential measurements verified (S21) 5 Product specifications (continued) General system specifications Power supply Universal 100 V to 240 V 10% Power line frequency 50 Hz to 60 Hz 10% automatically sensed Power consumption 15 VA Operating environment Full accuracy for 0C to 55C Full accuracy to 80% R.H. at 40 C Pollution degree 1 of IEC 61010-1 Storage environment -40C to 70C Dimensions (H x W x L) 40.9 x 212.3 x 379.3 mm 1.61 x 8.36 x 14.93 in Weight 3.8 kg, 8.4 lbs Safety conforms to CSA, UL/IEC/EN 61010-1 EMC conforms to IEC/EN 61326-1, CISPR 11 Warranty 3 years States 5 instrument states with user label in non-volatile memory Agilent connectivity software included Agilent I/O Libraries Suite version 14 or greater (E2094N) Memory Software Minimum system requirements PC hardware Intel Pentium 100 MHz, 64 Mbyte RAM, 210 Mbyte disk space Display 800x600, 256 colors, CD-ROM drive Operating system 1 Windows 98 SE/NT/2000/XP Computer interfaces Standard LAN 10BaseT/100BaseTx Optional IEEE 488.2 GPIB Software driver support for programming languages Software drivers IVI-C and IVI-COM for Windows NT/2000/XP, LabVIEW Agilent VEE Pro, T&M Toolkit (requires Visual Studio.
