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