GX-IO Extender 150
The GX IO-Extender 150 enhances the input and output (I/O) capabilities of a GX device, enabling seamless integration with additional sensors, controls, and external devices. It connects via USB, which also serves as its power source, providing a simple and efficient expansion solution. The device can be controlled using Node-RED on the GX device as well as the Switch pane in the user interface.
Features:
- 8 digital I/Os, configurable as 8 inputs, 8 outputs, or 4 inputs + 4 outputs
- PWM output for precise control applications
- Two latching relays for low-power switching
- A solid switch for controlling DC loads that can be resistive, capacitive, or inductive (such as the coil of a high-power contactor)
- Pluggable spring terminals for fast and secure connections
- Configurable via Node-RED for easy automation and custom logic
