APPLICATION: The FP-TP4PW, RU-TP4PW and TX-TP1PW are power inserters compatible with RDL
twisted pair products. Each is powered from a 24 Vdc power supply using either a power jack or the
terminal block. Power jacks are provided at each end of the FP-TP4PW to facilitate chaining multiple
modules from a single power supply. Dual-RJ45 jack sets are provided to connect remote twisted pair
senders and receivers. Power is provided to all modules connected to the RJ45 jacks. Signal pairs feed
through the associated RJ45s. The voltage feeding each dual-RJ45 jack set is separately protected by an
automatically resetting fuse. A power LED is associated with each dual-RJ45 jack set, facilitating
identification of wiring faults. Module power is indicated by a front-panel LED.

Typical Performance reflects product at publication time
exclusive of EMC data, if any, supplied with product.
Specifications are subject to change without notice.
Each PWR OUT LED indicates that power is present on the jack. If an LED is not illuminated, remove the associated output
connector(s), repair the wiring fault, and remove power from the module for 10 seconds. Re-power the module and note the LED is illuminated.
Reconnect the twisted pair cable(s); if the LED remains on, the wiring fault has been successfully cleared.
