B&R X20TB5E
Integrated terminal temperature compensation Tool-free wiring using push-in technology Simple wire release using a screwdriver Labeling option for each terminal connection Plain text labeling possible Access for standard test probes Customized coding possible This terminal block is equipped with 2 integrated PT1000 sensors. It is therefore ideally suited for internal terminal temperature compensation. This terminal block is used to wire the safe X20 thermocouple modules with 16 connections.
