2.6 Field Wiring
Detcon Model DM-100 sensor assemblies require two conductor connections between power supplies and host
electronic controller’s 4-20mA input. Wiring designations are PWR and mA (sensor signal).
NOTE
Shielded cable is required for installations where cable trays or conduit runs include high
voltage lines or other possible sources of induced interference. Separate conduit runs are
highly recommended in these cases.
NOTE The supply of power should be from an isolated source with over-current protection.
Terminal Connections – with Junction Box Option
CAUTION
Do not apply System power to the sensor until all wiring is properly terminated.
Refer to Section 2.7, Initial Start Up.
