2-channel isolated barrier

24 V DC supply (Power Rail)

Dry contact or NAMUR inputs

Input frequency 1 mHz ... 1 kHz

Current output 0/4 mA ... 20 mA

Relay contact and transistor output

Start-up override

Configurable by PACTware or keypad

Line fault detection (LFD)

Function :

This isolated barrier is used for intrinsic safety applications. It analyzes 2 digital signals (NAMUR sensor/mechanical contact)

from a hazardous area and functions as a rotation direction indicator, slip monitor, frequency monitor or synchronization monitor.

Each proximity sensor or switch controls a passive transistor output. The 2 relay outputs indicate if the input signal is above or below the trip

value or the rotational direction. The analog output can be programmed to be proportional to the input frequency or slip differential.

The unit is easily programmed by the use of a keypad located on the front of the unit or with the PACTware™ configuration software.

Line fault detection of the field current is indicated by a red LED and through the collective error output via Power Rail.
