1) Main functions and features
● Single channel, input circuit Intrinsic Safety, switch/proximity switch input.
● Electric contactor output, may select close (NO) / (NC) output function.
● Receive hazardous-area switch/proximity switch input, and transfer to standard electric level output to safe-area after isolated.
● Input, output and power supply are isolated from each other
● With contact status indicator light.
● Compact and light net weight, may be mounted in high density.
