1756-OW16I ControlLogix Isolated Relay Output Module for Industrial PLC Systems
| Place of Origin | USA |
| Brand Name | ControlLogix Controllers |
| Certification | CE |
| Model Number | 1756-OW16I |
Product Overview
1756-OW16I is a ControlLogix isolated relay output module used in industrial PLC systems, machine control cabinets, production line automation, and factory maintenance replacement. It is designed to provide relay contact output control from a 1756 PLC system to field devices such as interposing relays, contactor coils, pilot lights, alarms, small actuators, solenoid circuits, and machine control interfaces.
Unlike transistor output modules, a relay output module is often selected when the system requires dry contact output, wider load flexibility, or isolation between output points. This makes 1756-OW16I suitable for maintenance projects where the original panel wiring and load type must be matched carefully before replacement.
Main Features

Compatible System and Chassis Use
1756-OW16I is used in ControlLogix 1756 chassis systems together with controllers, communication modules, power supplies, terminal blocks, and other I/O modules. Before replacement, users should confirm the installed chassis, slot position, terminal block type, output wiring, load voltage, load current, and project configuration. Relay output modules should not be replaced only by appearance because contact rating and wiring method are important.
Industrial Applications
This module is commonly used in packaging machines, conveyor systems, material handling equipment, utility panels, production lines, machine tools, pump control panels, and general factory automation cabinets. It is suitable for applications where the PLC needs to switch relay-based loads or provide isolated contact outputs to external control circuits.
Maintenance and Replacement Notes
When replacing 1756-OW16I, confirm the complete catalog number, relay output requirement, terminal block, field wiring, load type, contact rating, chassis compatibility, and original nameplate. Output problems may also be caused by damaged loads, loose wiring, field power issues, or contact wear, so the external circuit should be checked before ordering.
