Low Voltage Models (24Vac); Ratiometric (0-5Vdc) Pressure And Temperature Probes; General Warnings - Emerson Dixell XC15CX Installing And Operating Instructions

4.2.2 Low Voltage Models (24VAC)


TRIAC output oA3 is internally connected to the power supply LINE (A1, terminal number 1)

Follow instructions on par. 4.3 for probe connections

Analogue output oAn can be a PWM (positive on terminal 18) or 0-10Vdc (positive on terminal 17)
type.

All digital inputs are free of voltage type

Model XC15CX has only a 16_A relay (oA1), TRIAC output (oA3) and analogue output (oAn)

PROBES

4.3.1 General Warnings

In case of using of terminal ends pay attention there are no bear parts which could cause short
circuiting or introduce noise disturbance at high frequencies. To minimize the induced
disturbances, use shielded cables with the shield connected to earth.
Pressure probes (0-5Vdc):
Pay attention to the polarity
Pb1 = 13(+5Vdc) - 14(in) - 16(GND)
Pb2 = 13(+5Vdc) - 15(in) - 16(GND)
Temperature probes:
lengthen the cables .

NTC10k: Pb1 (13-14) e Pb2 (13-15)

NTC10k or PT1000 or NTC86k: Pb3 (19-21) e Pb4 (19-20)
Pay attention that available temperature probes for analogue inputs Pb3 and Pb4 depends on
the HW. The possible combinations are: NTC10k or NTC86k and PT1000
