Function
This isolated barrier is used for intrinsic safety applications.
The device supplies 2-wire and 3-wire transmitters, and
can also be used with current sources.
Two relays and an active 0/4 mA to 20 mA current source
are available as outputs. The relay contacts and the current
output can be integrated in safety-relevant circuits.
The current output is easily scaled.
On the display the measured value can be indicated
in various physical units.
The device is easily configured by the use of keypad or
with the PACTware configuration software.
The input has a line fault detection.
A fault is signalized by LEDs and a separate collective
error message output.
