Hybrid I/O Design: 12 Inputs + 12 Outputs:Provides 12 digital input channels and 12 digital output channels in a single module, enabling integrated I/O configuration—reducing module count, saving panel space, and lowering wiring costs.
High Input Compatibility with Multiple Signal Types:Digital inputs support 24 V DC PNP or NPN signals, compatible with common industrial devices such as push buttons, sensors, and limit switches—offering high flexibility.
High-Performance Transistor Source (PNP) Outputs:12 high-speed transistor source (PNP) outputs, each capable of driving up to 0.5 A, suitable for directly controlling relays, solenoids, indicator lights, and other typical loads.
Fast Response for High-Speed Control:Typical input response time: < 1 ms, output response time: < 0.5 ms—ideal for fast-response applications such as packaging machines and sorting systems.
Plug-and-Play, Right-Side Expansion Design:Installs directly to the right side of M238 or M258 CPU modules, connects automatically via backplane bus—no additional power or communication cables required. The system auto-detects the module for fast deployment.
LED Status Indicators for On-Site Diagnostics:Each input and output channel features a green LED indicator showing real-time status; the module also includes RUN and FAULT LEDs for quick troubleshooting and maintenance.
