Product Description P/N: 1771-OGD
Description
The Allen-Bradley 1771-OGD is a PLC-5 digital DC TTL output module designed for use within the 1771 Universal I/O system. It provides 16 TTL outputs for controlling logic-level devices and requires both the chassis backplane supply and an external 5 VDC source for operation. This module is widely used in industrial automation systems for precise logic signal transmission and control.

Information About 1771-OGD
The 1771-OGD is part of the Allen-Bradley 1771 I/O family, developed for reliable integration with PLC-5 controllers. It supports 16 transistor-transistor logic (TTL) outputs with configurable logic switching modes (High = True or Low = True). The module operates with an output voltage range of 2–5.25 VDC (ON) and -0.2–0.8 VDC (OFF), with a maximum sourcing current of 1 mA and sinking current of 20 mA. An external 5 VDC ±0.25 V power supply with minimal ripple is required in addition to the backplane current (230 mA max). The unit features a maximum output delay of under 1 ms, 1500 V AC isolation, and fused output protection with 0.5 A, 250 V normal-blow fuses. Built for durability, it is certified by UL, CE, and CSA and designed to operate in environments from 0–60 °C with 5–95% non-condensing humidity. Although discontinued, it remains significant in legacy Allen-Bradley PLC-5 automation systems.
Key Features:
- Series: Belongs to the Allen-Bradley 1771 Universal I/O family.
- Outputs: 16 TTL outputs for logic-level device control.
- Logic Options: Selectable “High = True” or “Low = True” operation.
- Voltage Range: 2–5.25 VDC ON, -0.2–0.8 VDC OFF.
- Power Requirements: Requires 5 VDC external supply (310 mA max) plus chassis backplane power.
- Current Capacity: Supports up to 1 mA sourcing and 20 mA sinking per output.
- Protection: Outputs fused with 0.5 A, 250 V normal-blow fuses.
- Isolation: 1500 V AC RMS electrical isolation.
- Diagnostics: Equipped with module status indicators for troubleshooting.
- Compliance: UL, CE, and CSA certified for industrial use.
The 1771-OGD delivers reliable TTL output performance for legacy PLC-5 control systems in industrial automation.
