The D5400M Modbus thermistor input modules measure four 2252 ohm thermistors.
The D5400M Modbus thermistor input modules provide an isolated 15-bit measurement, analog to digital conversion and a linearization of the digital data. The digital data values are scaled in 16-bit unsigned integer data format that represents a percentage of full scale. See the Modbus scaling example link below.
The digital data values are transmitted to a host computer using the Modbus RTU serial protocol via an RS-232 or RS-485 serial connection. The D5000M series supports up to 247 Modbus RTU devices on one RS-485 serial port. Since Modbus protocol does not support RS-232 echoing, D5000M series modules cannot be daisy-chained. This limits you to one module per RS-232 serial port.
The D5400M Modbus thermistor input modules can be mounted on a DIN-rail using the MK-1 mounting kit.
