The Honeywell 2ML-RY2A is a digital output module commonly used in Honeywell MasterLogic and ControlEdge series programmable logic controllers (PLCs). It provides 16 relay-isolated digital output points, each capable of switching both AC and DC loads. This module is ideal for controlling various actuators in industrial automation applications such as solenoid valves, motors, and relays, offering reliable discrete output control with high electrical isolation to prevent interference between channels.
Each output channel on the 2ML-RY2A supports a rated load of 2 A at 24 V DC resistive loads or 2 A at 220 V AC (power factor = 1). The module has a minimum load rating of 5 V DC at 1 mA and maximum load voltages of 125 V DC and 250 V AC. It features low off-state leakage current (0.1 mA at 220 V), fast switching speed with an off-to-on response time under 10 ms and on-to-off under 12 ms, and a long mechanical and electrical life—rated for millions of on/off cycles under normal operating conditions. Output status LEDs provide visual confirmation of channel status, improving diagnostics and troubleshooting.
Technical specifications include an external connection via an 18-point terminal block connector secured with M3 screws. The module measures roughly 12.7 cm (length, width, height each) and weighs about 0.17 kg, making it compact and easy to install in standard PLC racks.
