The PLC Tools SIM-TRT Temperature RTD Simulator was developed to assist maintenance personnel and integrators in RTD analog input testing, troubleshooting and application development.

It temporarily replaces and simulates a 2-wire, 3wire or 4-wire Platinum 100 Ohm 385 RTD resistor.

Five fixed output settings are available: 32°F, 100°F, 250°F, 500°F and 1000°F.

A specific output selection made by connecting signal wire to one of the five output terminals

Do not connect more than one output at the same time

Important: Do not use this device for calibration of input modules or instruments. This device is a simple tester that provides simulated signal within a selected range.

Typical Three-Wire RTD Connection

Typical Two-Wire RTD Connection

Connect Com and one of Output terminals directly to the PLC input

4-Wire RTD simulation:
Connect dual wires to the Com terminal and dual
wires to one of the Outputs

Do Not Operate Device Unless Area Is Non-Hazardous
