B&R X67DM1321 X67 8-Channel Configurable Digital I/O Module
Product Overview
The B&R X67DM1321 is an IP67 digital mixed I/O module for the B&R X67 distributed I/O system. It provides eight digital channels that can be configured by software as inputs or outputs, allowing the same module to support different sensor and actuator combinations.
The digital inputs use sink circuitry, while the digital outputs use source circuitry. Two channels also provide additional counter functions. This makes the module suitable for field-mounted machine I/O, event counting and flexible decentralized automation layouts.
Main Features
- Eight digital channels configurable as inputs or outputs
- 24 VDC nominal I/O supply
- Sink-type digital input circuitry
- Current-sourcing FET digital outputs
- Output current rating up to 0.5 A per channel
- Two channels with additional counter functions
- Configurable digital input delay
- Short-circuit-protected outputs
- Individual output-channel diagnostics
- IP67 field-mounted construction
