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 and
a separate collective error message output
