Product Description
The Allen-Bradley 1771-OG PLC 5 TTL Output Module, designed for installation in a 1771 I/O chassis slot, provides eight sinking/sourcing outputs with a 2-5.25V DC (High) and -0.2-0.8V DC (Low) output voltage range. Each output can source up to 1mA or sink up to 20mA. It requires a separate 5V DC power supply (0.25V, 50mV ripple max, 250mA) for TTL signal transmission. The module has a 1ms maximum signal delay, dissipates 2.2W (7.5 BTU/hr), and draws 168mA from the backplane. It offers 1500V AC (RMS) isolation for 1 second. The 1771-OG includes a 1771-WC field wiring arm (7-9 inch-pounds torque) and supports up to 14-gauge stranded wire (Belden 8761 recommended). Keying is achieved by connecting the keying band between backplane pins 6-8 and 10-12. It operates between 0-60C (32-140F) with 5-95% non-condensing humidity and can be stored between -40-85C (-40-185F).
Is Your Device Showing These Signs?
The Allen Bradley 1771-OG output module commonly experiences failures due to blown output fuses, resulting in a loss of signal to field devices. Technicians often troubleshoot issues related to shorted outputs caused by wiring faults or malfunctioning connected equipment. Corrosion on the edge connector pins impedes proper communication with the PLC backplane, necessitating cleaning or replacement. Overvoltage or overcurrent conditions damage the module's internal components, leading to erratic behavior or complete failure. Resolve these issues by replacing blown fuses, isolating and repairing wiring faults, cleaning connector pins with appropriate solvents, and ensuring proper voltage and current levels are maintained within specified parameters.

Our Repair Process for the
1771-OG
Our repair process for the Allen Bradley 1771-OG output module begins with a thorough inspection to identify blown output fuses, shorted outputs, corroded edge connector pins, and any signs of overvoltage or overcurrent damage. Blown fuses are immediately replaced with appropriately rated replacements. Technicians isolate and repair any wiring faults or malfunctioning connected equipment causing shorted outputs. Edge connector pins are meticulously cleaned with specialized solvents to remove corrosion and ensure optimal communication. We verify that voltage and current levels are within specified parameters, and any module exhibiting erratic behavior or complete failure due to internal component damage undergoes component-level repair or module replacement.
