Product Introduction
The Westinghouse / Emerson 4256A84G13 (QID G13) is a specialized digital input module belonging to the robust Q-Line product family utilized within legacy Westinghouse and Emerson control system environments (such as WDPF and early Ovation platforms).
The QID (Quadrature Input Digital / Digital Input) card is engineered to acquire discrete 220V AC signals from industrial field devices—such as limit switches, auxiliary contact feedbacks, and status indicators—and convert them into safe, isolated logic-level signals readable by the system controller. It provides reliable, high-integrity status monitoring for heavy power generation, water treatment, and continuous industrial process applications.

Compliance & Standards Alignment
- Manufactured in accordance with rigorous Westinghouse and Emerson industrial quality assurance standards for heavy-duty power plant and process automation hardware.
- Engineered with high noise immunity and built-in transient suppression to withstand heavy electrical noise, inductive spikes, and electromagnetic interference (EMI) typical of high-voltage switchgear environments.
Technical Note: The
G13designator signifies a specific input voltage rating (220V AC). Never substitute a card with a different voltage suffix (such as 120V AC or 24V DC versions) into the same slot without verifying field wiring and terminal block power ratings to prevent severe equipment damage or safety hazards.
Storage & Asset Preservation Guidelines
- Store the circuit card inside its original factory ESD-shielded antistatic packaging to safeguard surface-mount micro-circuitry and optocoupler isolation chips from static discharge.
- Keep the warehouse environment clean, dry, and climate-controlled, maintaining relative humidity below 85% (non-condensing).
- Avoid mechanical heavy shocks, drops, or physical twisting forces on the printed circuit board substrate or rear edge-connector fingers.
Physical Installation Prerequisites
- Ensure that all rack power rails, field voltage distribution sources, and associated digital input loops are completely de-energized, isolated, and locked out (LOTO) prior to inserting or extracting the card.
- Observe strict electrostatic discharge (ESD) safety protocols, including wearing a tested ground strap while handling internal electronics.
- Align the card carefully with the rack’s backplane slot guide rails and push firmly to seat the edge connectors before securing any retention fasteners or extraction latches.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this Westinghouse Q-Line card?
A: Industrial process control system cards, electronic input modules, and modular automation hardware typically classify under HS code 8538.90 (Parts suitable for use with electrical control apparatus) or 8537.10. Confirm final details with your customs broker.
Q: Is part 4256A84G13 interchangeable with other QID card suffixes?
A: No. Each G-code designation corresponds to a specific input voltage class (e.g., G11 is typically 120V AC, G13 is 220V AC). Always match the exact part suffix to your plant’s loop drawings.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, surplus condition tiers, and global shipping logistics; contact our technical sales desk for a formal, time-sensitive quotation.
