Isolated Barrier, Single Channel, 85/253 VAC, Switch Amplifier

This Ex rated single channel isolated barrier, with digital input, also known as a switch amplifier, is used for intrinsic safety applications for field side connection. This Isolated Barrier transfers digital signals (SN/S1N proximity sensors and approved mechanical contacts) from a hazardous area to a safe area. An additional protective circuit is used to maintain a reliable safety function.

A sensor or switch controls 1 safety output with 3 form A normally open relay contacts, 1 standard output with 1 form A normally open relay contact, and 1 error message output with a passive transistor. Lead breakage and short circuit conditions are continuously monitored. During an error condition, fault output energises and outputs I and II de-energise.

Isolated Barrier, Switch Amplifier Features

  • 1-channel isolated barrier
  • Voltage rating 85/253 VAC
  • Input for dry contacts or SN/S1N Sensors
  • Relay contact output
  • Error message output
