Function
This signal conditioner provides the isolation for nonintrinsically safe 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 and a
separate collective error message output.
