1762-OW16 16-Point Relay Output Module AC/DC | Allen-Bradley

The Original New Allen-Bradley 1762-OW16 16-Point Relay Output Module is a MicroLogix expansion I/O module designed for flexible AC/DC load switching in compact industrial control systems. It provides 16 normally open relay outputs organized into two isolated groups of eight, allowing simultaneous control of different voltage levels within a single module. This dry contact architecture eliminates the need for interposing relays in many applications, simplifying cabinet wiring and reducing overall system cost. Fully compatible with MicroLogix 1100, 1200, and 1400 controllers.

Core Engineering Highlights:
16 relay outputs (normally open) | 2 isolated groups of 8 outputs each | 5–265V AC / 5–125V DC operating voltage range | 2.5A max per point | 10 ms signal delay | 120 mA @5V / 140 mA @24V bus current draw | 6.1W heat dissipation | 2 isolated groups for mixed voltage control | 10 ms typical response time | IP20 protection rating | 0°C to +55°C operating | –40°C to +85°C storage | Removable terminal block with finger‑safe cover

Key Features:

Installation Notes:

• Each of the two isolated groups has its own common, allowing simultaneous control of different voltage levels

• For inductive DC loads, install a 1N4004 diode reverse‑wired across the load for surge suppression

• For inductive AC loads, use a snubber circuit to prevent contact arcing and extend relay life

• A minimum load current of approximately 10mA is recommended to maintain low contact resistance ("wetting current")

• Individual relays are soldered to the PCB — if a contact fails, replace the entire module

• Refer to Industrial Automation Wiring and Grounding Guidelines (Allen‑Bradley publication 1770-4.1)

• Close DIN rail latches before mounting the module

• The module may not be more than 6 modules away from the power supply
