-HART modem SM100-C(III)

To connect the HART temperature transmitter with computer, HART MODEM is needed. our HART modem SM100-C(III) is very flexible with built-in 250 ohm resistor and 24VDC source, there is no need to include a separate 24VDC source when commissioning the transmitter, which makes the wiring very easy during the configuration process.

-Size and Dimension

-Wiring diagram

1) The power source goes to terminal 1 and terminal 2
2) This item works with 2 wires, 3 wires and 4 wires RTD sensors, for 2 wires RTD, the two wires goes to terminal 4 and 5, and jump a wire between 3 and 4, jump another wire between 5 annd 6, for 3 wires RTD sensors, three wires connected to terminal 3, 4 and 5, and addtional to that, must jump a wire between 5 and 6. for 4 wires RTD, 4 wires connected to terminal 3, 4, 5, 6. the part where most likely being overlooked is for the 3 wires RTDs, a wire must be jump externally between terminal 5 and 6 for a 3 wire RTDs.
