Full Name:32 Channel Hot Swappable PLC Output Module, 24V DC Sourcing Solid‑State Output
Brand:Allen‑Bradley
Series:1769 Compact I/O, CompactLogix System Matching Module
1. Product Overview (What It Does)
The 1769‑OB32 is a high‑density discrete digital output expansion module exclusively designed for CompactLogix PLC control systems. It delivers 32 channels of 24V DC sourcing output (split into two independent 16‑point groups) to drive external industrial field actuators, indicator lights, solenoid valves, small relays, conveyor sensors, and machine signal devices. The core highlight is built‑in hot swap function: technicians can remove/replace the module while the PLC chassis and production equipment remain powered on, no full system shutdown required, drastically cutting equipment downtime during maintenance. As a solid‑state non‑relay output unit, it supports fast high‑frequency switching for automated production lines, acting as the signal execution terminal between PLC logic programs and on‑site physical loads.
2. Core Product Advantages & Key Features
Icon: Hot Swap Symbol | Non‑Stop Maintenance Full hot swappable design; module replacement without powering down the PLC rack, eliminate long production stops for I/O fault repair.
Icon: 32 Digital Points Icon | Ultra High Density Layout 32 output channels in single 1‑slot footprint, reduces cabinet space occupation by 50% vs low‑density modules, lower panel manufacturing cost.
Icon: DC Voltage Symbol | 24V DC Sourcing Output Sourcing type (high‑side) output, supply +24VDC positive to loads; industry standard wiring scheme, lower risk of accidental machine startup caused by ground short circuit.
Icon: LED Light Symbol | Real‑Time Channel Diagnostics LED Independent status LED for each of 32 channels; instantly view on/off status and fault alarm without extra detection tools.
Icon: DIN Rail Icon | Dual Installation Mode Support standard DIN rail mounting + direct panel screw mounting, flexible layout for compact control cabinets.
Icon: Shield EMC Symbol | Industrial‑Grade EMC Anti‑Interference Meet IEC EMC immunity standards (ESD, surge, fast transient burst), stable operation under factory electromagnetic noise environment.
Icon: Thermal Resistance Icon | Wide Temperature Operating Range -25℃ ~ +60℃ working temperature, adapt to cold warehouse, hot workshop, semi‑outdoor automation equipment.
Icon: Solid State Chip Icon | Fast Response Solid‑State Circuit Max 0.1ms turn‑on delay, 1.0ms turn‑off delay; support high‑speed repeated switching, no mechanical contact wear like relay modules.
