1.7.3 Wiring Std 0/4-20 mA Analog Outputs
The standard configuration of the Model XGM868i flow transmitter includes two isolated 0/4-20 mA analog outputs
(designated as outputs 1 and 2). Connections to these outputs may be made with standard twisted-pair wiring, but the
current loop impedance for these circuits must not exceed 600 ohms.
To wire the analog outputs, complete the following steps:
1. Disconnect the main power and remove the rear cover.
2. Install the required cable clamp in the chosen conduit hole on the side of the electronics enclosure.
3. Refer to Figure 10 on page 25 for the location of terminal block J1 and wire the analog outputs as shown. Secure
the cable clamp.
Note: Analog outputs 1 and 2 in the wiring diagram correspond to analog outputs A and B in Slot 0 in the XGM868i
software.
!ATTENTION EUROPEAN CUSTOMERS!
To meet CE Mark requirements, all cables must be installed as described in Appendix A,
CE Mark Compliance.
4. If wiring of the unit has been completed, reinstall the rear cover on the enclosure and tighten the set screw.
WARNING! Make sure both covers, with their o-ring seals, are installed and the set screws tightened before
applying power in a hazardous environment.
Note: Prior to use, the analog outputs must be set up and calibrated. See Chapter 1, Calibration, of the Service
Manual for detailed instructions.
Proceed to the next section to continue the initial wiring of the unit.
