Availability: Enquire about stock

ACT20X, EX signal isolating converter, 1-channel version

£97.89 excl. VAT

ACT20X-HDI-SDO-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 an NPN switching transistor and a common alarm contact 

(relay/"a" contact) for status or error messages.

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