Power Inserter / Signal Breakout-Twisted Pair Format-A

Ideal Use Cases

The RDL TX-TP4PW is designed for Format-A twisted-pair installations that need power for remote senders and receivers supplied from a convenient location. Its four associated RJ45 jacks provide power output, while pairs A, B and C remain connected between all four RJ45 connectors. This configuration is suited to systems in which power insertion and signal breakout must coexist within one module. The TX-TP4PW can power up to three high-current Format-A receivers, providing a clearly defined capacity for system planning.

Why Choose This Model

The TX-TP4PW combines a 24 Vdc power input, four RJ45 power outputs and visible operating indicators. Power enters through a dc power jack. A blue Power In LED shows that the module is receiving power, while a green Power Out LED indicates correct dc output voltage at the RJ45 connectors. These separate indicators make both input power and output-voltage status directly observable. Each RJ45 output supports a maximum load current of 200 mA, giving installers a specific per-output limit for matching connected equipment.

The module measures 3.0 inches wide, 1.2 inches high and 1.4 inches deep. These published dimensions make it possible to evaluate the required installation space before ordering or integration.

Installation and Integration

Install the TX-TP4PW in an ambient operating environment between 0° C and 55° C. Connect a suitable 24 Vdc source to the module’s power jack. The specified power requirement is 24 Vdc at 15 mA plus the requirements of the connected loads. RDL identifies the PS-24AS as the recommended power supply for the USA and the PS-24AX for international applications.

Once input power is connected, the blue LED confirms that the module is receiving power. The green LED provides confirmation of correct dc output voltage on the RJ45 connectors. RJ45 cabling and connected Format-A equipment can then be arranged while retaining the stated connection of pairs A, B and C across all four RJ45 connectors. Load planning should account for both the 200 mA maximum on each RJ45 output and the stated capacity of up to three high-current Format-A receivers.

Performance Highlights

The electrical design centers on four RJ45 power outputs and a defined maximum load of 200 mA for each output. The module itself requires 15 mA in addition to the connected loads at 24 Vdc. Its green output indicator is specifically tied to correct dc output voltage on the RJ45 connectors, providing more information than input-power indication alone.

The published 200 mA rating applies to each RJ45 output. No combined aggregate output-current figure is provided in the source data, so system planning should use the stated per-output rating without treating it as a published total-load specification. The supported device capacity is explicitly stated as up to three high-current Format-A receivers.

What Makes It Different

The defining feature of the TX-TP4PW is the combination of power insertion with signal breakout in a twisted-pair Format-A configuration. All four RJ45 connectors carry the identified pair continuity for pairs A, B and C, while the associated jacks provide power output. This gives the module a specific role within Format-A distribution systems rather than functioning only as a standalone dc input device.

Separate blue and green LEDs distinguish incoming-power status from correct output-voltage status. The four RJ45 outputs, per-output current rating and defined three-receiver capacity provide concrete integration limits. Its power-jack input also establishes a straightforward interface for the recommended USA or international power-supply options.

Final Assessment

The RDL TX-TP4PW is a focused power-insertion and signal-breakout module for Format-A twisted-pair systems. It is best matched to installations requiring four RJ45 power outputs, continuity of pairs A, B and C, and support for up to three high-current Format-A receivers. Selection should be based on compatibility with 24 Vdc power, the 200 mA maximum for each output and the stated operating range. Dual status LEDs provide direct confirmation of power input and correct dc output voltage.
