The Weidmuller 8965350000 ACT20X-HDI-SDO-RNC-S is an EX signal isolating converter with one channel. It is designed with an Ex-input for NAMUR sensors or switches and a safe-output relay with NC contact. This device transmits digital signals, galvanically isolated, from potentially explosive atmospheres to safer areas. The input circuits are intrinsically safe and can process NAMUR sensor signals.
EX signal isolating converter, 1-channel
Ex-input: NAMUR sensor/switch
Safe-output: relay, NC contact
Product Highlights
This converter is designed for recording NAMUR sensor signals and digital switching signals from Ex zone 0, enhancing system availability with integrated alarm contacts for malfunction alerts.
