Opto-22 G4ODC5R Digital Dry Contact DC Output Module

The Opto 22 G4ODC5R is a digital dry contact DC output module engineered for industrial automation systems within the G4 I/O family. It employs a Form A, SPST-NO mechanical reed relay to switch low-voltage DC resistive loads while maintaining 4000 V transient optical isolation between field devices and control logic. The module operates on 5 VDC logic and includes a built-in status LED.

– Key Features

• Optical isolation protects control circuits from field-side transients
• Low coil current draw of 14 mA minimizes controller load
• Fast switching response with 500 µs turn-on and turn-off times and <500 µs contact bounce
• Extended mechanical life rated at 5 million cycles for high-reliability applications
• Built-in LED status indicator for field diagnostics

– Typical Applications

Analog signal multiplexing, communication line switching, and DC load control in industrial control systems where galvanic isolation is required.

– Compatibility & Integration

Designed for Opto 22 G4 I/O family integration. Compatible with Totem Pole or Tri-State output modules. Not compatible with G4PB4R mounting racks. Load must be purely resistive; inductive and capacitive loads are not recommended due to inrush current constraints. Steady-state and momentary inrush must not exceed 10 VA.
