isolating signal converter ST 500-Ex - Greisinger electronic

isolating signal converter

properties:

Isolating signal converter for application in zone 0 or zone 20 (permanent explosion risk)
with integrated transmitter supply.
It allows the direct connection of active 2-wire sensors (4 to 20 mA) and 3-wire sensors in the Ex-area.

input intrinsically safe ATEX II (1) GD [EX ia] IIC
2 power-supply-designs with wide range of allowed supply voltage:
10 to 30 V DC / AC or 85 to 253 V AC
electrically isolated between input/output/supply voltage
22.5mm standard housing for rail mounting TS35
universal inputs/outputs for (0)4 to 20 mA and 0 (2) to 10 V
