Common Pain Points
Traditional digital input modules often suffer from limited channel count restricting multi-signal acquisition, poor anti-interference causing false triggers in noisy industrial environments, short communication distance limiting remote deployment, insufficient isolation leading to equipment damage from surges or ground loops, narrow power range causing instability, complex wiring and addressing for expansion, and compatibility issues with modern IoT/PLC systems — severely impacting reliability, scalability, and efficiency in industrial automation and monitoring projects.
Solution & Core Features
1.High-Density 16-Channel Input — 16 isolated digital inputs supporting both dry contact (passive) and NPN-type (active) signals, compatible with proximity switches, infrared sensors, push buttons, wall switches, etc.
2.Strong Industrial Isolation & Protection — Photoelectric + DC-DC isolation (1500V surge withstand), IEC-compliant ESD/surge protection, overcurrent/overvoltage/reverse polarity safeguards for superior noise immunity and equipment safety.
3.Flexible Long-Distance Communication — Dual interfaces: RS232 (≤15m) or isolated RS485 (up to 1200m), standard Modbus RTU/ASCII protocol, supports multi-module daisy-chain cascading with unique addressing for easy network expansion.
4.Wide Voltage & Extreme Environment Adaptability — DC 7-30V wide input (compatible with 9V/12V/24V sources), -40°C to +85°C full industrial temperature range, 35mm DIN rail mounting for harsh field deployment.
5.Seamless Integration & Reliability — Plug-and-play with mainstream PLCs, SCADA, and IoT gateways; compact design (102.5×70×35mm), low power, LED indicators for power and channel status.
