ACT20X-HDI-SDO-RNC-S Details

Ex isolating switch amplifiers for Namur sensors

1-channel isolating switch amplifiers in 22.5 mm width with an external power supply,

to transmit and isolate Namur sensor signals from Ex zones 0,1,2 into the safe zone. 

On the output side there is a potential-free relay contact with opening function and an alarm contact ("a" contact)

for status/error messages.

The component can be configured using standard FDT/DTM software.
