8DI/8DO
Modbus Ethernet IO Module: Modbus PoE ETH IO 8CH provides 8 digital inputs + 8 digital outputs for industrial control, supporting Modbus TCP / Modbus RTU over wired Ethernet for reliable remote IO.
Built-In IEEE 802.3 af PoE + 736V DC Input: Supports PoE power supply (IEEE 802.3 af) and DC 736V wide voltage power, simplifying installation and cabinet wiring for this PoE Ethernet IO controller.
Passive/Active DI (NPN/PNP) + Debounce + Linkage: Supports passive and active digital input (NPN/PNP) with bi-directional optocoupler isolation and built-in debouncing
supports DI/DO linkage control or DO toggle control for automation logic.
8DO 500mA Sink Open-Drain Outputs: Outputs use Darlington transistor open-drain with optocoupler isolation, up to 500mA sinking current per channel, plus flyback diode protection for driving relays/solenoids and other loads.
Dual Ethernet Cascade + Isolation Protection + DIN Rail: Features dual Ethernet ports for communication and cascade, plus power isolation/optocoupler isolation, TVS surge suppression and resettable fuse
DIN rail mount case with LEDs for IO/MCU/status monitoring.
