1762-OB16 Allen-Bradley MicroLogix 16-Point Digital Output Module
The Allen-Bradley 1762-OB16 is a versatile 16-point digital output module designed for the MicroLogix series of programmable logic controllers (PLCs), including the MicroLogix 1100, 1200, and 1400. It delivers reliable on/off control for industrial automation applications, with configurations available for both relay and transistor outputs to suit diverse load requirements. This module is ideal for driving solenoid valves, motor starters, indicator lights, and other discrete field devices.
Key Features
Flexible Output Configurations
Relay Output (Form C Contacts): 16 independent relays with normally open (NO) and normally closed (NC) contacts, supporting high-current loads up to 2A per channel at 30V DC or 250V AC
Transistor Output (24V DC Source): 16 solid-state MOSFET outputs, each capable of sourcing 2A at 24V DC, with fast switching (8ms on/off delay) and low power consumption (~10W)
Robust Isolation & Protection
Channel-to-Group Isolation: Relay outputs are grouped into 4 isolated sets (4 channels per group), enabling independent power supplies for different loads. Transistor outputs feature optocoupler isolation to prevent electrical interference
Overcurrent & Short-Circuit Protection: Built-in circuitry safeguards against load faults, extending module lifespan in harsh industrial environments
Seamless Integration
MicroLogix Compatibility: Supports up to 4 modules with MicroLogix 1100, 6 with MicroLogix 1200, and 7 with MicroLogix 1400
EtherNet/IP & DeviceNet Support: Communicates via industrial protocols for real-time data exchange with PLCs and supervisory systems
User-Friendly Design
Status Indicators: Per-channel LEDs display output status (on/off) and power health, simplifying troubleshooting
Flexible Installation: Mounts on DIN rails or panels using integrated latches, with removable terminal blocks for quick wiring
