SDM-5190 is 16 Channel isolated digital / switch input module, which is widely used in industrial field, signal acquisition, monitoring and control. It has 16 channels of isolated digital input, and 1~16 channels of digital input has counter function. Each channel of DI0-DI15 has a 32-bit counter, which can measure the switching pulse within 200Hz.The communication interface is 2-ports RS-485 interface that supports the standard MODBUS-RTU protocol and can be connected to configuration software, PLC, and DCS industrial touch screen etc.
Features
1. supports 2-Ports RS-485 Interface and can be connected to two different master stations.
2. Supports standard Modbus RTU protocol and has simple configuration.
3. Supports 1024 Digital and 256 Analog expansion Modbus buffers for easy data exchange between master stations.
4. Provide Windows configuration tool software for module management, configuration, and debugging.
5. Digital input and output, power supply, and communication are indicated by LED lights.
6. Supports AC/DC10~30V wide voltage supply, and supports overcurrent and overvoltage protection.
