Omron NX-OD4256 NX Series 8-Point PNP Digital Output Module

Omron NX-OD4256 NX Series 8-Point PNP Digital Output Module

Description:
Omron NX-OD4256 is a digital output unit for the NX series I/O system. 8 PNP (sourcing) transistor outputs rated at 0.5 A per point, 4 A per unit. Standard speed signal processing with 0.5 ms ON and 1.0 ms OFF response time. Screwless push‑in terminal block for tool‑free wiring. 12 mm width for high‑density mounting. Part of the NX series for EtherCAT communication coupler systems.

Applications:

• Solenoid and relay actuation in machine control systems

• Conveyor and material handling equipment

• Packaging machinery and assembly lines

• Factory automation I/O expansion

System Integration:

• This module belongs to the Omron NX series I/O system.

• Requires an NX series communication coupler unit（e.g., EtherCAT or EtherNet/IP）for operation.

• I/O refreshing can be synchronised with the controller cycle via EtherCAT.

• Mounts on 35 mm DIN rail.
