Common Pain Points
Traditional digital I/O modules often face limited channel counts unable to cover multi-device control, weak isolation leading to noise/surge interference, low relay load capacity preventing direct drive of high-power devices, narrow power voltage range causing instability in field power supply, short communication distance restricting remote deployment, complicated address setup hindering expansion, and poor temperature tolerance unsuitable for extreme environments — severely impacting stability, scalability, and efficiency in industrial automation, smart home, and IoT projects.
Solution & Core Features
1.High-Density 8DI + 8DO Configuration — 8 opto-isolated digital inputs (support dry contact/wet contact, NPN/PNP) + 8 high-load relay outputs (277VAC/10A), one module meets multi-channel switch acquisition and control needs.
2.Industrial-Grade Isolation & Protection — 5000V opto-coupler isolation on inputs, hardware watchdog anti-crash, multi-level surge/overcurrent/overvoltage/reverse polarity protection for strong noise immunity and device/host safety.
3.High-Load Direct Drive Capability — Relay contacts rated up to 277VAC/10A & 30VDC/10A, directly drives 220V lamps, solenoid valves, motors, etc. (380V devices via contactors).
4.Wide Temperature & Voltage Stability — DC 5–36V wide input (compatible with 9V/12V/24V sources), -40°C to +85°C full industrial temperature range, suitable for outdoor/high/low-temperature harsh environments.
5.Easy Modbus Integration — Standard Modbus RTU protocol, RS485/RS232 interface support, DIP switch quick addressing, multi-module cascading expansion, seamless compatibility with PLC/SCADA/LabVIEW/cloud platforms, true plug-and-play.
