Connection

Assembly

• 1-channel isolated barrier

• Universal usage at different power supplies

• Input for NAMUR sensors or dry contacts

• Input frequency 1 mHz ... 5 kHz

• Current output 0/4 mA ... 20 mA

• Relay and transistor output

• Start-up override

• Line fault detection (LFD)

• Up to SIL2 acc. to IEC 61508/IEC 61511

Function

This isolated barrier is used for intrinsic safety applications.

The device is a universal frequency converter that changes a

digital input signal into a proportional free adjustable

0/4 mA ... 20 mA analog output signal and functions as a

switch amplifier and a trip alarm.

The functions of the switch outputs (2 relay outputs and

1 potential free transistor output) are easily adjustable [trip

value display (min/max alarm), serially switched output, pulse

divider output, error signal output].

The device is easily configured by the use of keypad or with

the PACTware configuration software.

A fault is signalized by LEDs acc. to NAMUR NE44.
