IO Expansion Module 24DI 16DO with CAN and RS485 Networking

The JIO2416 is an IO Expansion Module 24DI 16DO designed for machine builders who need to grow the signal count of a controller without adding a second node. With 24 digital inputs and 16 digital outputs on a single module, it monitors equipment status and drives actuators on mid-sized machines while keeping the cabinet layout compact and the wiring plan predictable.

Wide I/O Count for Machine Signal Handling

The module accepts 24 digital input signals from limit switches, proximity sensors, push buttons, and other discrete field devices, and provides 16 digital output channels for relays, contactors, and solenoid valves. Because all channels share a 24 VDC supply, integration into an existing control panel does not require a separate power rail.

Deterministic 50 µs Refresh

At a 50 µs refresh cycle, the module communicates process states to the controller quickly, keeping the scan image current for time-sensitive interlocks and actuator commands. This refresh speed matters most in high-cycle machinery where a missed sensor edge can interrupt a production sequence.

Network Flexibility and Setup

CAN and RS485 communication let it join different industrial network architectures. A simple DIP-switch interface sets baud rate, terminal resistor and node address, removing software debugging and cutting deployment time on the production line.

Where a 24DI/16DO Expansion Module Fits Best

Typical deployments include factory automation, robotics, packaging, CNC machine tools, semiconductor equipment, inspection, and material handling. In packaging cells the inputs track container presence while the outputs drive cylinder valves; on CNC machines the module handles auxiliary signals such as coolant, interlocks, and work-light control without burdening the axis controller.

Selection Considerations

Confirm the controller supports CAN or RS485 at the node address you intend to use, and verify the 24 VDC supply is stable at the mounting location. Because the module is powered from the same bus as the controller, cable routing and shielding should follow standard industrial practice to avoid noise on the signal lines.
