Product information
Overview
Key Features
- Digital I/O capacity: Has 16 digital inputs and 16 digital outputs; inputs are arranged in groups of 2 and outputs in groups of 1.
- 24 V DC supply: Rated supply voltage is 24 V DC, with a permissible range from 20.4 V to 28.8 V DC.
- Digital inputs: Inputs support Sink/Source operation and have a 24 V DC rated input voltage. The input characteristic curve follows IEC 61131, type 1.
- Transistor outputs: Outputs have a 24 V DC rated voltage and 0.5 A rated output current. Switching capacity is up to 0.5 A with resistive load and 5 W on lamp load.
- Diagnostics and protection: Provides diagnostic alarms and LED indications for input and output status. The protection degree is IP20; short-circuit protection is not provided and must be supplied externally.
- Mounting capacity: Maximum capacity is 16 for all mounting positions up to 40 °C, horizontal installation up to 50 °C, and vertical installation up to 40 °C.
