Common Pain Points
Traditional I/O modules often suffer from channel/signal inflexibility limiting multi-type device integration, narrow voltage/temperature tolerance causing failures in harsh environments, low relay load capacity unable to directly drive 220V/380V loads, weak isolation leading to interference/crashes, and complex setup hindering fast integration with PLC/SCADA/LabVIEW systems — severely reducing reliability, adaptability, and deployment efficiency in industrial automation and IoT projects.
Solution & Core Features
1.Flexible Multi-Function Configuration — 4 digital inputs (dry/wet contact, opto-isolated), 4 high-load relay outputs, and 4 analog inputs (switchable 0-10V / 4-20mA), one module covers switch acquisition, power control, and analog monitoring needs.
2.Industrial-Grade Reliability — 5000V optoelectronic isolation on inputs, hardware watchdog anti-crash, -40°C to +85°C wide temperature operation, DC 5-36V wide voltage input for extreme environment stability.
3.High-Load Direct Drive — Relay contacts rated 277VAC/10A & 30VDC/10A, directly drives 220V lamps/valves/motors (380V loads via contactors).
4.Strong Anti-Interference & Protection — Multi-level surge/overcurrent/overvoltage/reverse polarity protection, robust noise immunity for reliable field operation.
5.Easy & Fast Integration — Standard Modbus RTU protocol, DIP switch quick addressing, plug-and-play compatibility with PLC/SCADA/LabVIEW/cloud platforms.
