The Allen-Bradley 1771-OMD is a 16-point digital output module designed for PLC-5 systems. It supports both AC and DC output loads and is rated for 220 Volts AC operation. This module is powered directly through the backplane by the chassis power supply, drawing 700 milliamps at 5V DC. Its outputs are ideal for interfacing with AC/DC input modules or controlling external devices in industrial automation environments. Compact and robust, the 1771-OMD integrates seamlessly into 1771 I/O chassis, making it a practical choice for legacy system support and expansion in control systems.
