Physical and Electrical Specifications

Backplane Integration and Deterministic Data Handling

The 1KHW001223R0002 P4LT hardware interfaces directly into the subrack backplane, ensuring high backplane bus communication velocity across system slots. Dynamic bandwidth assignment allows integration with up to four NSK600 AF modems alongside the MOD600 DPLC modem. Built-in firmware flash compatibility maintains signal synchronism through the MUX600 multiplexing structure under high channel-density scaling.

Standard Shipping Configuration

• 1 x ABB 1KHW001223R0002 P4LT ETL600 Signal Module
• 1 x Protective Electrostatic Discharge Shield Sleeve

Installation and Shielding Protocol

Subrack Insertion Procedure

• Power down the backplane rack section before aligning the circuit card with the frame chassis slots.
• Press firm on the front ejector handles to seat the rear multi-pin connector into the backplane receptacle without pin bending.

RF and Ground Connection Rules

• Terminate all high-frequency signal lines using shielded coaxial cabling rated for target line impedance.
• Attach low-impedance grounding straps between the rack chassis and central cabinet earthing bus prior to power application.

Frequently Asked Questions

• What primary signal transformation is executed by the 1KHW001223R0002 P4LT module?

  The module converts internal low-frequency (LF) baseband voice and data signals into high-frequency radio frequency (RF) bands for line transmission.

• How many voice or data modems can be connected simultaneously to the board?

  The board architecture supports direct integration of up to four NSK600 audio frequency (AF) modems alongside the MOD600 DPLC modem.

• How is the module powered within the chassis assembly?

  Operational power is drawn directly from the regulated DC system power supply through the backplane bus interface connector.

• Is hot-swapping allowed during active transmission cycles?

  Rack power to the specific slot must be isolated before insertion or removal to prevent signal corruption on active channels.

• What data multiplexer unit operates on this card assembly?

  The module utilizes the MUX600 data-multiplexer architecture to consolidate multiple voice and teleprotection channels into the RF spectrum.

• How does backplane communication speed impact signal latency?

  High-velocity bus architecture minimizes propagation delay during LF-to-RF conversion and multiplexing steps across the ETL600 rack.

• What precautions must be observed regarding electrostatic discharge during handling?

  Engineers must wear a grounded wrist strap attached to chassis earth when handling the unshielded circuit board edges.

• Does the module require physical calibration of RF output levels upon installation?

  Parameter configuration and gain levels are managed via firmware flash setup and software tool interfaces upon system power-up.
