Gas Safety Barrier Battery Powered

Used for the safe operation of electrical equipment in hazardous areas, the unit ensures that the power from the BMS to the gas meter is at a SAFE voltage, therefore avoiding explosive situations.

Features:
– 2 inputs and 4 outputs
– Can be configured by a jumper link to enable either,
– Input 1 drives all 4 outputs or
– Input 1 drives one pair of outputs and Input 2 drives the other pair of outputs.

The unit can be configured by a jumper link so that output pulses are 50mS duration or 250mS duration.
Designed for use with volt-free contact or open collector/drain meter outputs. Input ‘ídle’ voltage is around 3.6v.
Input voltage must be pulled below 0.5v @ 30uA to register as an input pulse. Minimum input pulse width 20mS.

Maximum pulse frequency:-
– 10Hz with 50mS output pulse duration
– 2Hz with 250mS output pulse duration

Additional Features:-
Maximum voltage across each output 60v DC
Maximum current through each output 100mA
Isolation between outputs 1Kv DC
Battery life >10 years (1 input driving 4 outputs. Max. frequency 1Hz). Input to output isolation voltage 13.9Kv DC
