The DAT1485 is a Modbus Temperature Transmitter that converts Thermocouples, RTD's Potentiometers, Resistance, and mV to Modbus RTU or Modbus ASCII. The DAT1485 is head-mounted and designed to fit into a DIN B head mounting enclosure. The sensor input, power supply, and the Modbus output are isolated from each other.
The DAT1485 Modbus Temperature Transmitter is PC programmable using the RS485 port and the Datexel software, which is free. The communication protocols are selectable such as Modbus RTU or Modbus ASCII, Modbus parity, Baud rate, and the stop bits. The input is also selectable, and has three different ranges for mV. The ranges are -100mV to 90 mV, -100mV to 200mV, and -100mV to 800mV. The different types of Thermocouples are K Type, J Type, R Type, S Type, T Type, B Type, E Type, and N-Type. The different types of RTD are Pt100, PT1000, Ni100, and NI1000 2 wire RTD or 3 wire RTD. The DAT1485 also can select the range of 500 Ohm or 2000 Ohm resistor input and 500 ohm and 50 kohm potentiometers. For the temperature input, you have the choice of "f "c or Kelvin.
The sensor inputs are linearized for Thermocouples and RTD's.
