ELFD Controller Carrier

The ELFD Controller Carrier provides a mounting platform for up to two SafetyNet
Controllers (8851-LC-MT). It can also accommodate a Power Supply Monitor module
(8410-NS-PS) which can monitor the health of up to two 8913-PS-AC, four 8914-PS-AC
power supplies and the 12V supply to Intrinsically Safe Modules (when these are used).
For each Controller there is a serial port connector and a manually operated ““Change
State” button. The Carrier also provides terminals that are used when earth leakage fault
detection is required.
