JUMPFLEX®, 857 Series
Bipolar isolation amplifi er, confi gurable
857-409
Before installation and operation, please read the following instructions thoroughly and carefully. Incorrect
installation may compromise safety in the event of a failure.
1. Safety Information
Please observe the following:
- the applicable laws, standards and regulations
- the current, accepted technology standards and practices at the time of installation
- the operating instructions
- the engineering regulations
- the fact that operating instructions can only mention general regulations
and that these must be observed
Before start-up, please check the device for any damage that may have occurred during shipping. The device
shall not be put into operation in the event of mechanical damage.
The devices described in these instructions must only be installed by a qualifi ed electrician and must only be
installed in electrical switchgear or in sealed enclosures. Improper use or failure to follow this application note
will render the warranty or guarantee null and void.
The devices shall only be installed in dry, indoor areas.
Do not install the devices on or in the vicinity of easily fl ammable materials.
2. Short Description
The bipolar isolation amplifi er records bipolar analog signals (e.g., ±10 V or ± 20 mA) and converts them into
bipolar, analog standard signals. After conversion, the isolated signals are transmitted with high accuracy to the
output where they are available in an amplifi ed form. In addition, unipolar signals (e.g., 0-20 mA or 0-10 V)
and live zero signals (e.g., 4-20 mA or 2-10 V) can be adjusted independently of one another at both input and
ouput via DIP switches. Adjusting the limiting frequency is also performed via DIP switches.
Measured distance adjustment is carried out via zero/span potentiometers on the front of the device, while si-
gnal switching is performed in a calibrated way, which requires no adjustment when switching to another range.
The device is supplied with 24 VDC, which can be effi ciently commoned using lateral push-in type jumper bars.
A green LED on the front panel indicates normal operation.
The bipolar isolation amplifi er provides safe isolation of input, output and supply circuits with 2.5 kV test voltage
to EN 61140.
The current input is protected against overloading by a reversible fuse. The fuse switches back automatically as
soon as the overload is no longer active.
3. Installation
CAUTION: High voltage can cause electric shock or burns.
De-energize the system and the device before installation.
Caution: Take protective measures against electrostatic discharge (ESD) when operating the modules!
The devices snap onto DIN 35 rails without tools. A simple screwdriver is required to unlock the snap-on
mounting foot and remove the device from the carrier rail. Potentials can be commoned using 859 Series
2- to 10-way push-in type jumper bars (see accessories). The jumpers must be inserted prior to connecting the
conductors for ease of installation. Push down the jumpers until fully inserted (see installation instructions).
Use separators (item no. 209-191) between adjacent contacts for safe electrical isolation if the modules are
alternately rotated 180 degrees when snapped onto the rail.
For secure fi xing on the carrier rail, end stops (e.g., WAGO 249-116) must be mounted at the ends of a
module assembly.
Observe the maximum admissible conductor cross-sections of the signal and power wires.

8. LEDs and Error Indication
The LED (green), which is visible on the front, displays the following status:
Green LED lights: Operating voltage applied
9. DIP Switch Adjustability
▯ = ON
4. Zero/span adjustment
Always use an insulated screwdriver when performing a zero/span adjustment (e.g.
WAGO 210-619)
The zero/span potentiometers are used to adjust the output signal when analog signals are
too low or too high.
Example: A sensor, which is connected to the input of the isolation amplifi er, delivers a
analog signal of maximum 9.7 V. Using the zero/span potentiometer, the signal can be
readjusted to 10.0 V.
