More info

This new generation Smart IO Modules based on RS485 Modbus communication is available now for data acquisition and other applications. These IO Modules offer good reliability, easy for installation, easy maintenance, wide range of operating input power, communication isolation of 3000VDC, watchdog timer to monitor remote host such as PC, PLC, PAC. They can be easily added into existing RS485 modbus network. Different types of IO Modules are available for the users to select as per their requirement. All Modules are having LED indications for monitoring the status of inputs(Digital) and fault diagnostics. Analog input modules are available with universal inputs also. They can accept voltage, current and thermocouple signals. The analog inputs are isolated between channels. Special modules are available with high interchannel isolation between channels and high isolation betweeen channel and ground for special applications. These IO Modules can configured as slaves with Modbus RTU Protocol to communicate with Modbus Master such as PLC, HMI, SCADA. All IO Modules have 2 wire RS485 Interface with Modbus RTU Protocol.
