Honeywell 05701-A-0351 Analytics Control Card

The Honeywell 05701-A-0351, also cataloged as the 05701-A-0351 Analytics Control Card, operates as a dedicated hardware component for single-channel gas telemetry acquisition and signal conditioning within Honeywell System 57 control racks.

Hardware Specifications

4-20 mA HART Loop Protocol & Channel Isolation

The Honeywell 05701-A-0351 Analytics Control Card processes analog measurement signals from single-channel field gas detectors while maintaining channel-to-channel isolation across the backplane bus. The circuitry conditions field sensor inputs operating on an 18 V to 32 V DC supply, controlling signal drift within +/-2% under standard operation. It provides direct physical signal routing for 4-20 mA HART loop protocol instruments, preventing ground loop noise coupling and maintaining signal integrity across the System 57 processing backplane.

Frequently Asked Questions

Q: What is the input DC voltage operating window for the 05701-A-0351 control card?

A: The module operates within an input supply range of 18 V to 32 V DC, drawing approximately 3.75 W of continuous power under standard operation.

Q: How does the card prevent signal degradation across the backplane?

A: The card incorporates channel-to-channel galvanic isolation and noise-suppression traces that limit electronic drift to less than +/-2%.

Field Installation Guidelines

1. De-energize the System 57 rack power distribution block and apply standard ESD grounding protection before touching the module.
2. Align the 05701-A-0351 card with the intended slot guides on the System 57 rack frame.
3. Push the module firmly into the card slot until the rear connector seats flush into the backplane receptacle.
4. Tighten the top and bottom front-panel retention screws to lock the card in place and ensure frame grounding continuity.
5. Verify that all field transmitter signal cables utilize shielded cabling, with shields grounded at a single earth point at the cabinet entry bar.
