Description
HONEYWELL 0571-A-0328 Product Description
Product Overview
HONEYWELL 0571-A-0328 is a DC digital input card associated with Honeywell industrial gas-detection and automation equipment. Available industrial automation references specifically identify 0571-A-0328 as a DC input card and associate it with the SC-PCMX01 51307195-175 hardware family.
The HONEYWELL 0571-A-0328 is intended to receive discrete DC status signals from field devices and transfer their states into the supervisory or control architecture. It can be used for monitoring alarms, switches, detectors, interlocks and other binary field conditions. Some commercial listings associate this model with industrial and commercial gas-detection applications and list Modbus as the communication interface, although these details should be verified against the exact system revision before engineering use.
For legacy Honeywell automation and gas-detection installations, 0571-A-0328 provides an important field-interface function. Its principal value is reliable acquisition of discrete DC signals, allowing the control system to identify equipment status, alarm conditions and safety-related events and initiate the appropriate monitoring or control response.

*Publicly available sources associate 0571-A-0328 with Modbus, but detailed electrical ratings such as nominal input voltage, channel count, input current and threshold levels could not be reliably verified from a primary Honeywell document. These values should therefore be confirmed from the equipment nameplate and original system documentation.
Main Features and Advantages
Dedicated DC Digital Input Interface
The HONEYWELL 0571-A-0328 provides a dedicated interface for acquiring DC discrete signals. Instead of directly connecting numerous field contacts to a controller, the card organizes field-state information into a structured industrial I/O architecture.
Reliable Status Acquisition
The module can be used to monitor binary conditions such as detector activation, equipment running/stopped status, valve position, pressure-switch operation and alarm contacts. This allows the control system to continuously distinguish normal operating conditions from abnormal states.

Gas-Detection Application Compatibility
Available industrial listings specifically associate 0571-A-0328 with gas-detection applications in industrial and commercial environments. This makes the module particularly relevant to systems where discrete detector and alarm signals must be collected and transmitted to a supervisory control platform.
Compact Field Integration
As a dedicated input card, 0571-A-0328 can consolidate multiple discrete signals within an industrial control cabinet. This helps reduce point-to-point wiring complexity and provides a more organized interface between field detectors and the supervisory system.
Suitable for Alarm and Interlock Monitoring
Digital input acquisition is fundamental to industrial safety and automation. The module can support alarm contacts, permissive signals and interlocks that allow the higher-level control system to determine whether equipment is ready to operate or whether protective action is required.
Legacy System Maintenance
For installed Honeywell systems, maintaining an exact 0571-A-0328 spare can be useful when replacing a failed input card. Industrial automation references also list 0571-A-0325 and 0571-A-0328 within the same broader Honeywell spare-parts inventory, making it important to verify the exact model rather than assuming similarly numbered cards are interchangeable.
Application Fields
HONEYWELL 0571-A-0328 is primarily suited to industrial monitoring systems requiring reliable acquisition of DC discrete signals. Its application is particularly relevant to gas detection, alarm monitoring and equipment-status acquisition.
In oil and gas facilities, the module can interface discrete signals from gas detectors, alarm contacts, emergency devices and equipment interlocks. The collected information can be passed to the supervisory system so operators can quickly identify abnormal field conditions.
In petrochemical and chemical plants, 0571-A-0328 can support field status monitoring around process units, pumps, compressors, storage areas and hazardous zones. Digital input points can be used for detector activation, valve position feedback, equipment permissives and shutdown-related contacts.
In power and industrial utilities, the card can monitor binary operating states from auxiliary equipment, electrical cabinets, alarms and protection-related contacts. This provides the automation system with a structured source of discrete status information.
The module is also relevant to industrial and commercial gas-detection systems, manufacturing facilities and other installations where multiple field alarms and discrete detector outputs need to be integrated into a centralized monitoring architecture. Available listings specifically describe the 0571-A-0328 application in industrial and commercial gas detection.
For replacement projects, engineers should verify the input voltage, channel configuration, terminal/interface arrangement and associated Honeywell controller or detector system before installation. Publicly available documentation for this specific part number is limited, so exact electrical compatibility should not be inferred solely from the model number.
