Description

Product Description: Control Component HONEYWELL 261A1812P012

The HONEYWELL 261A1812P012 is a specific part number for a Honeywell control component, likely from their building automation, HVAC, or industrial valve/actuator product lines. This alphanumeric code identifies a precise model variant, potentially a temperature sensor, a pressure transducer, a zone controller, or a specific part of a larger control assembly like a valve actuator module. The part number follows Honeywell’s detailed manufacturing coding, where each segment provides information about the product family, specifications, and configuration. For exact identification and technical data, please consult the official resource: HONEYWELL 261A1812P012. Sourcing the correct HONEYWELL 261A1812P012 is essential for maintaining the performance of the specific system it serves.

Key Parameters

• Part Number Interpretation: The number is structured to convey specific attributes. ‘261A’ likely indicates the base product family (e.g., a series of electronic actuators, specific sensors). ‘1812’ could denote key specifications like voltage (18V), torque, or a version code. ‘P012’ is a configuration suffix indicating options like mounting, connector type, or output signal.
• Primary Function: Based on common Honeywell numbering in this range, the HONEYWELL 261A1812P012 is highly probable to be an Electronic Actuator or Positioner for control valves, or a Smart Thermostat/Controller. It could also be a Pressure or Temperature Transmitter with a specific electrical output.
• Electrical Specifications: If an actuator, it will have defined supply voltage (e.g., 24V AC/DC), power consumption, control signal type (e.g., 0-10V DC, 4-20mA, floating point), and feedback signal. If a sensor, it will have an input range and output signal.
• Mechanical Specifications: Includes details such as mounting pattern, stroke length (for actuators), shaft type, enclosure rating (e.g., IP54, NEMA 4), and temperature operating range.
• Communication: May include analog signaling or, if a more modern device, digital communication protocols like Modbus, BACnet MS/TP, or LonWorks for integration into building or industrial networks.
• Compatibility: Designed to work with specific Honeywell valve bodies, controllers, or system frameworks.

For maintenance teams, the exact HONEYWELL 261A1812P012 part number is the key to a direct, trouble-free replacement.

Application Case Studies in Various Fields

• HVAC System Control: Modulating the flow of hot or chilled water through a coil in an Air Handling Unit (AHU) or Variable Air Volume (VAV) box to maintain zone temperature setpoints.
• Industrial Process Control: Automatically adjusting a process control valve on a chemical feed line, steam line, or fuel line based on a controller’s 4-20mA signal.
• Energy Management: Regulating water flow in a district heating or cooling system to optimize energy transfer and reduce waste.
• Building Automation: Serving as the actuating component in a room-level thermostat or damper control system for optimal comfort and efficiency.
• Water Treatment: Controlling the dosage of treatment chemicals (e.g., chlorine, pH adjusters) by modulating a valve based on water quality sensor inputs.

Comparison with Competing Products
The HONEYWELL 261A1812P012 competes with similar actuators, positioners, or sensors from manufacturers like Siemens (Belimo, formerly), Johnson Controls, Schneider Electric, and Azbil. Its competitive edge lies in Honeywell’s strong reputation in control technology, the potential for seamless integration with other Honeywell building or process controllers, and widespread availability of support. Compared to generic or unbranded components, the HONEYWELL 261A1812P012 offers assured quality, documented specifications, and technical support. The choice often comes down to existing system vendor preferences and the specific performance requirements of the application.

Selection Suggestions and Important Precautions

1. Absolute Identification is Key: Use the full part number HONEYWELL 261A1812P012 exactly as it appears on the original component or in system documentation. Do not guess or assume based on similar numbers.
2. Match All Specifications: Verify voltage, control signal type, torque/stroke (for actuators), pressure range (for sensors), and mounting details against the original component’s requirements. A mismatch can lead to failure or poor performance.
3. Consider the Control System Compatibility: Ensure the new component’s signal type (analog, digital) is compatible with the existing controller’s output/input card. Check if any recalibration or controller configuration changes are needed.
4. Verify Mechanical Compatibility: For actuators, confirm the mounting pattern, shaft size, and travel match the existing valve body. Using an incompatible actuator can cause mechanical binding or failure.
5. Source from Authorized Suppliers: Purchase the HONEYWELL 261A1812P012 from authorized Honeywell building automation or industrial distributors to avoid counterfeit products. After installation, perform calibration and a full functional test of the control loop to ensure proper operation. Document the replacement in the equipment maintenance log.
