The IE1001 digital input module acquires the binary control signals from the process level and transmits them to the higher-level automation unit. The input filter is 3.0 ms. The state of the signals is indicated by light emitting diodes. The signals are connected via M8 screw type connectors.
The sensors are supplied from the box supply voltage US. The auxiliary voltage UP is not used in the input module, but may be connected in order to be relayed downstream.
