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 sensor
A 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.
