Product Details

Configured for manual interface switching and serial command transmission in ABB HKQCS platforms, the ABB 086351-004 (086351-004 Serial Pushbutton Board Assembly) provides direct physical/electrical execution. The printed wiring assembly (PWA) conditions operator pushbutton contact inputs and encodes them into digital serial signals for processing by host control nodes.

Hardware Specifications

Backplane Bus Communication Velocity and Deterministic Networks

The serial pushbutton assembly coordinates digital contact events directly across system interface buses, maintaining high backplane bus communication velocity across connected operator consoles. Low propagation delay prevents command latency over Profinet and EtherNet/IP deterministic networks, enabling expanded I/O density scaling and maintaining hardware firmware flash compatibility across legacy HKQCS system architectures.

Frequently Asked Questions

Q: What legacy part numbers does the 086351-004 serial pushbutton assembly replace?

A: The 086351-004 replaces older revision IDs including Y086351-004, Y086351-001, and Y086351-003.

Q: How are operator switch signals routed from the 086351-004 board?

A: Switch actuation signals are serialized on the board logic circuits and transmitted via dedicated multi-pin connector headers directly to the system backplane or operator panel bus.

Field Installation Guidelines

  1. System De-Energization: Disconnect power to the control panel before removing or installing the serial pushbutton assembly.
  2. Anti-Static ESD Handling: Use a grounded ESD wrist strap while unboxing and installing the PWA card to prevent static discharge damage to sensitive IC components.
  3. Mechanical Alignment: Align the board edges with the panel guide tracks and slide the assembly in until the edge connector seats fully into the backplane mating socket.
  4. Fastener Retaining: Secure all retaining screws along the board mounting frame to ensure frame earth ground continuity and mechanical stability.
