Bus expansion module TRS-IO-E

I/Oindustrialdigital

TRS-IO-E is an expansion unit part of the TRS series, designed to be mounted on DIN rails. The interface towards the coupler is a TRS bus, that means that, for it to function, the module needs to be connected through that bus to a TRS coupler. Each module has 16 bidirectional digital I/O lines. Each line is configurable either as input or as output. TRS-IO-E is compliant with the EMC directive 2004/108/EC. INPUT FUNCTIONS Synchronous input sampling with constant delay; False max. limit 18 Vdc; current draw of each input: 3 mA. OUTPUT FUNCTIONS Highest current per output: 0.5 A; output overload and overvoltage protection (36 V); real-time output re-reading (software diagnostics); output activation synchronous with communication on TRS bus.
