Figure 4: MAQ20-RTD31 Slidewire Sensor Wiring
MAQ20-RTD41 standard sensor wiring is shown in Figure 5 below. When using MAQ20-RTD41,
4-Wire connections reject leadwire effects regardless of wire length, gage, and mismatch. All four
sensor wires and extension wires must run the entire distance from the module input terminal block
to the sensor.
Shield terminals are connected to the Field Side low impedance potential and are isolated from the
Bus. If shield drain to system ground is required, this connection must be made external to the module
and must not compromise the Field Side to Bus isolation barrier. A capacitor with working voltage
rating of 2000V or higher can be used between Field Side shield and Bus for this purpose.
