Figure 3 20 Low Level Pulse Input Module Field Wiring Schematic 3 4 15 RTD Input Module The RTD input module monitors the temperature signal from a resistance temperature detector RTD sensor or probe The RTD module is isolated reducing the possibility of lightning damage A Lightning Protection Module LPM will not protect the RTD but it helps protect the rack in which the module is installed 3 17 Input Output Modules Rev Mar 05 ROC306 ROC312 Instruction Manual The RTD module must to be calibrated while disconnected from the RTD probe therefore it may be more convenient to perform calibration before connecting the field wiring However if the field wiring between the ROC and the RTD probe is long enough to add a significant resistance then calibration should be performed in a manner that takes this into account For a three or four wire RTD with the wires used to connect up each leg are of the same length and size the error generated will be zero or at least no different for any given length This is because the RTD input uses the resistance of the wire loop s not passing through the RTD to correct for the wire resistance of the loop with the RTD 3 4 15 1 Calibrating the RTD Module The following instructions describe how to calibrate an RTD input channel for use with an RTD probe having an alpha value of either 0 00385 or 0 00392 ohms degree C This procedure requires a resistance decade box wi
