Product Description
The Allen-Bradley 1769-OB16 is a compact, solid-state 16-channel 24VDC output module compatible with MicroLogix 1500 and CompactLogix controllers. It features a voltage range of 20.4-26.4VDC, with output delays of 0.1ms (on) and 1.0ms (off). Key specifications include a 200mA draw at 5.1V, 2.11W heat dissipation, 1.0mA leakage current at 26.4VDC, and a minimum on-state current of 1.0mA. It has a maximum on-state voltage drop of 1.0V at 1.0mA. The module supports a maximum current per point of 1.0A at 30C and 0.5A at 60C, with a maximum current per module of 8.0A at 30C and 4.0A at 60C, and a surge current of 2.0A for 10ms (repeatable every 2s). It offers IEC Class 2 reinforced insulation up to 75VDC. The single-slot module can be DIN rail or panel mounted and measures 4.65 x 1.38 x 3.43 inches, weighing 0.61 lbs. It can drive 24VDC loads directly or AC loads via interposing relays. When used with CompactLogix, it must be within 8 modules of the power supply. It is compatible with 1769 CompactLogix power supplies like the 1769-PA2/PB2/PA4/PB4 and uses the included 1769-RTBN18 terminal block, supporting wire sizes of 22-14 AWG (solid) and 22-16 AWG (stranded).
Is Your Device Showing These Signs?
The Allen Bradley 1769-OB16 output module commonly experiences issues such as blown output fuses due to overcurrent conditions from inductive load switching or wiring faults. Technicians address short circuits in field wiring, resolve backplane communication errors stemming from corrupted firmware or faulty connections, and correct addressing conflicts within the CompactLogix PLC system. Module failures are often attributed to electrostatic discharge (ESD) damage during handling or thermal stress from improper installation in high-temperature environments. Resolve intermittent operation by inspecting and reseating the module within the chassis to ensure proper electrical contact.
Technical specifications
The Allen-Bradley 1769-OB16 is a compact 16-channel 24VDC solid-state output module for MicroLogix 1500 and CompactLogix controllers. It has specific voltage, current, and timing characteristics, including output delays, leakage current, and on-state voltage drop. It supports specific current limits per point and per module, dependent on temperature, and offers surge current protection. The module features reinforced insulation, can be DIN rail or panel mounted, and has defined physical dimensions and weight. It can drive DC loads directly or AC loads via relays and requires specific power supply considerations when used with CompactLogix. It utilizes a 1769-RTBN18 terminal block and supports specific wire gauges.
Our Repair Process for the
1769-OB16
Our repair process for the Allen Bradley 1769-OB16 output module begins with a thorough inspection for blown output fuses, which are replaced after identifying and correcting any overcurrent conditions or wiring faults. Technicians meticulously examine field wiring for short circuits and resolve any backplane communication errors by updating corrupted firmware or repairing faulty connections. Addressing conflicts within the CompactLogix PLC system are corrected, and the module is inspected for signs of electrostatic discharge or thermal stress. Intermittent operation is resolved by inspecting and reseating the module within the chassis to guarantee proper electrical contact.
