General Specification

The 8-channel digital input terminals (positive switching) acquire the binary control signals from the process level and transmit them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminals contain eight channels which indicate their signal state by means of light emitting diodes. They are particularly suitable for space-saving use in control cabinets. By using the single-ended connection technique, a multi-channel sensorClosedA sensor is a type of transducer that converts one type of energy into another for various purposes including measurement or information transfer can be connected in the smallest space with a minimum amount of wiring. The power contacts are looped through.

For the Bus Terminals, the reference ground for all inputs is the 0 V power contact.
