2.2. Field Power Connection
May be connected at the T8871 Field Termination Adapter. However Field Power may be connected
any where along the cable by pulling the Field Power Cables (Grey & White) out of the outer sheath
and connecting onto suitable junction boxes.
2.2.1. Cable Impedance
Custom length multi-core FTA cables are 0.5mm 2 with a resistance of 40M/km. eg a 50m cable will
have 4M loop impedance at 0.5A, this equates to a 2Vdc volt drop.
2.3. Termination
Unused channels should be commanded OFF and may be fitted with a 33k 2W resistor to prevent no-
load detection.
2.4. Module Pinout Connections
Field Connections are made to the Modules DIN41612 type D Field Connector:
