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

nd connecting onto suitable junction boxes.

2.2.1. Cable Impedance

Custom length multi-core FTA cables are 0.5mm

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:
