Isolated RTD Modules
HE693RTD660E
The Horner APG Isolated Resistance Temperature Detector (RTD) Input Modules allow RTD temperaturesensors to be directly connected to the PLC without external signal processing (transducers, transmitters,etc.). All analog and digital processing of the RTD signal is performed on the module. These backplaneisolated (or bus-isolated) modules have programmable resolutions in increments of 0.05oC, 0.05oF,0.1oC, 0.1oF, 0.5oC, 0.5oF. The module features six channels whose temperature values are reported tothe 6 %AI input registers. There are 6 %I alarm bits and one setpoint alarm for each channel. Alarmsetpoints are configured for each channel using 6 %AQ registers. All modules feature support for thefollowing RTD types: PT-100 (platinum, 100W at 0°C), Ni-120 (nickel, 120W at 0°C), Cu-10 (Copper,10W at 25°C), Pt-1000 (platinum, 1000W at 0°C), and TD5R Silicon (Microswitch).There are three versions of the Horner APG Isolated RTD Input Module: HE693RTD660, HE693RTD666,and HE693RTD665. The HE693RTD660 is a six-channel module with 1500V AC isolation to the PLCbackplane and 5V AC isolation channel-to-channel. The HE693RTD666 is equivalent to theHE693RTD660 with the addition of a 60Hz notch filter. The HE693RTD665 is also equivalent to theHE693RTD660 with the addition of a 50Hz notch filter. The purpose of these filters is to eliminate noisegenerated by power lines in the United States (60Hz) and Europe (50Hz)
