The Interbus S-Line input module uses 8 digital inputs to read 24 V sensors in PNP technology into the INTERBUS loop. Along with four of these digital inputs, the input/output module additionally provides 4 digital outputs for 24 V actuators also in PNP technology. The sensors and actuators are connected via 3-pos. M8 screw connectors and preassembled sensor cables.
For the inputs, mechanical switches with 2 contacts (e.g., limit switches) are connected in the M8 female connectors via the +24 V pin and the IN x pin (2-conductor connection). Initiators (e.g., light sensors or proximity sensors) are additionally connected to the ground contact (3-conductor connection). The supply voltage for the sensors is provided via the bus line, thereby eliminating the need for additional wiring effort. The sensor supply is short-circuit-proof and provides power to all sensors with 3-conductor connection up to 150 mA.
The loads are connected to the outputs (DIO 4/4/8 only) short-circuit-proof via the OUT x contacts and ground of the M8 output female connectors. For all output female connectors, the 24 V supply is applied at the 3rd contact. This supply voltage must be provided via one of the 4 output female connectors.
