Introduction

Main Functions

Digital Discrete ON/OFF Output Control It is a basic I/O unit for CJ‑series PLC backplane bus. It receives logic output data from the CJ‑series CPU, and turns external DC loads ON or OFF via 32‑channel NPN sinking transistor outputs. Rated operating voltage: DC 12‑24 V (allowable range:10.2‑26.4 VDC). Each channel supports maximum 0.5 A output current; total unit current limit is 4.0 A.plcva.com
Optical Isolation & Circuit Protection Optocoupler isolation is implemented between internal PLC circuit and external field circuits to suppress electrical noise and improve anti‑interference capability. Built‑in channel‑level short‑circuit protection prevents hardware damage caused by field‑side short‑circuit faults. Individual LED status indicators show ON/OFF status for each output channel for quick on‑site diagnosis.plcva.com
Fast Switching Response Max ON‑response time: 0.1 ms; Max OFF‑response time:0.8 ms. It delivers stable medium‑speed discrete switching for general‑purpose digital loads, suitable for most ordinary automation signal control scenarios (not for ultra‑high‑speed pulse output).
High‑density Compact I/O Expansion 32 output points within narrow 20 mm module width, saving cabinet mounting space. It adopts detachable FCN40‑pin Fujitsu connector interface, supporting fast wiring and module replacement without rewiring field cables. No COM terminals; it uses IOV and IOG power terminals for external load power distribution.
Standard CJ‑bus Integration Mounted on CJ‑series CPU backplane, automatically allocated I/O memory addresses by PLC system. No special configuration software required; works directly with CX‑Programmer programming environment.plcva.com

Applications / Purposes

High‑density discrete output expansion for CJ‑series PLC systems Mainly used to expand large‑quantity digital output points for CJ1/CJ2 PLC controllers inside control cabinets, ideal for projects demanding many DO channels with limited cabinet space.
Control general DC24V field actuators Drive solenoid valves, indicator lamps, signal lights, small‑size relays, contactor coils, solid‑state relays SSR and other DC‑powered field‑side actuators on production equipment.
Factory automated machinery & production lines Widely deployed on assembly machines, packaging equipment, conveyor systems, material handling machines and automated assembly lines to perform sequence logic control for field actuators.
Distributed cabinet‑based automation solutions Applied in machine‑cell control, packaging lines, logistics automation equipment and industrial retrofitting projects. The high‑density 32‑point design reduces total quantity of I/O modules and lowers overall system cost.
