Applications
- IO-Link device communication: The module provides IO-Link master communication for connected IO-Link devices through its 4 ports.
- Digital signal operation: The module supports DI and DQ operating modes for digital input and output operation.
Key Features
- IO-Link master ports: 4 IO-Link ports are available, and all 4 ports can be controlled simultaneously. Port types A and B are supported; port type B provides 24 V DC via an external terminal.
- Operating modes: IO-Link, DI, and DQ operation are supported. DQ output current is limited to 100 mA per channel.
- Supply voltage: Rated supply: 24 V DC. The permissible range is 19.2 V to 28.8 V DC; 20.5 V is required when IO-Link is used.
- IO-Link communication: IO-Link protocol 1.0 and 1.1 are supported. Transmission rates are 4.8 kBaud (COM1), 38.4 kBaud (COM2), and 230.4 kBaud (COM3).
- Diagnostics and protection: The module has supply-voltage monitoring, wire-break, short-circuit, and group-error diagnostics, plus green PWR, channel-status, red Fn, and green/red DIAG LEDs. Reverse-polarity and short-circuit protection are provided.
- Rail installation and dimensions: The module is rail-based and measures 15 mm wide, 73 mm high, and 58 mm deep. Horizontal operation is supported from -40 °C to 60 °C; +70 °C is supported for 10 minutes under OT2, ST1/ST2 conditions.
