180mV. the maximum allowable lead wire resistance can be determined for any application.

7.1.1 Maximum lead Resistance for RTD The maximum total resistance including the RTO and the two lead wires that carry the RTD excitation current is: 180mV 0.180= = 600 Ohms 0.3mA 0.0003 If a 100OPt RTO is used to measure a maximum temperature of 700°C. then the RTD resistance is 345 ohms and the maximum lead wire resistance for both leads combined is 600-345 = 255 Ohms. Similarly, the permissible maximum lead wire resistance can be calculated for other RTO applications.

... .L." ." ." I i" 2.3.1 Output Terminals The output terminals, 9 & 10, are connected generally to a power supply having a nominal 24 Volt DC voltage and capable of supplying 1 0OmA for the SC-2000. Although in the analog mode these signal conditioners require a maximum of only 24mA, for digital communications with the SC-2000 the power supply capacity should be 1.QOmA. The + OUT and -OUT terminals of the signal conditioner are connected to the corresponding polarity terminals of the power supply.Optionally a load resistor, typically 250 ohms, may be connected in series with either terminal of the signal conditioner (for digital communications with the SC-2000 this 250 ohm resistor is re-quired). The maximum series resistance in the circuit (including wiring lead resistance) can be calculated using the formula: Vs -12 Rs = ------- in ohms 0.023 The following chart gives maximum series resistances:

Supply Voltage Vs Max. Series Resistance Rs 42.0 Volts 1300 ohms 24.0 Volts 520 ohms 21.6 Volts 417 ohms 18.0 Volts 250 ohms 12.0 Volts 0 ohms 2.3.2 Case Ground Terminal 8 provides a connection to the metal enclosure of the signal conditioner.

For safety, optimum performance and EMI immunity the case of the instrument should be connected to a good local earth ground. When using grounded sensors which are connected to the local electrical ground, then the signal conditioner case should be connected to that same ground point.-7-Cdc~~m 9- &od2o5' Pev. A
