Properties & technical data

A module unit is made up of a terminal module and an electronics module. These are connected using a secure sliding and locking mechanism. The terminal module combines clamps, a fixture for the electronics module and the backplane bus connector. This means only the electronics module is replaced during servicing, by simply pulling it out of the terminal module. The wiring and mounting on the 35 mm DIN profile rail remain as they are. The electronics modules can be supplied with voltage and/or divided into separate potential groups by using additional supply modules. The stepped arrangement of terminals on the terminal module using proven spring-clamp technology with highly reliable contacting enables fast, clear and safe wiring. The integrated status LEDs and the labeling strip on the front of the electronics modules ensure unique, channel-specific assignment and clear display of the channel status. The backplane bus concept with a speed of 48 Mbit/s also makes for very short response times.
