IM80
The IM80 is a precision programmable analog input module designed for use in a distributed measurement or control system. Eight measurement channels allow the connection of RTDs, TC thermocouples, or 4-20mA current signals. The input signals are processed in an 18-bit A/D converter. The data received from the transmitter is digitally linearized and processed by the microprocessor system, and then made available to the master system via the COM1 (RS-485 / Modbus RTU) SLAVE communication port. The second COM2 (RS-485 / Modbus RTU) MASTER communication port allows you to connect additional IM80 modules to increase the number of measurement channels.
The device is designed to measure and recording process signals in industrial installations and can be used to measure physical quantities converted into a standard signal, such as: temperature, humidity, pressure, flow, level, chemical composition, etc.
