Foxboro FBM242Output Channels

  • Contains 16 discrete output channels, enabling simultaneous control of multiple external devices.

Voltage Support

  • Supports discrete output signals with multiple voltages, including 15-60V DC, 120V AC/125V DC, and 240V AC, meeting the input voltage requirements of different field devices.

Electrical Isolation

  • Each output channel is electrically isolated, and group isolation is applied when used with external excitation, effectively preventing electrical interference between channels and enhancing system stability and reliability.

Environmental Adaptability

  • Compact and durable, with an Acrylonitrile Butadiene Styrene (ABS) housing, suitable for cabinets in harsh G3-level industrial environments, resisting dust, moisture, chemical corrosion, and other adverse factors.

Functional Configuration

  • Executes discrete I/O or ladder logic programs, with configurable options such as input filter time, fail-safe configuration, fail-safe fallback, and continuous or momentary output, allowing flexible settings to meet different control requirements based on specific applications.

Terminal Assemblies

  • Includes various terminal assemblies (TA), such as current limiters, fuses, relay outputs with external power/fuse/power distribution, solid-state outputs, redundant power distribution, etc., providing multiple connection and protection methods for field devices.

Visual Indication

  • Light Emitting Diodes (LEDs) are installed on the front of the module to intuitively display the module's operating status and the discrete status of each output point, facilitating on-site monitoring and fault troubleshooting.

Easy Installation

  • Installed on a Compact 200 series baseplate for DIN rail or horizontal rack mounting. When disassembling/replacing the module, field device terminal cables, power supply, or communication cables do not need to be removed, enabling convenient maintenance and replacement.

Communication Function

  • Connected to fieldbus communication modules or control processors via a redundant 2Mbps module fieldbus, accepting communication from either path (A or B) of the redundant fieldbus. Even if one path fails, the module can still communicate via the active path, ensuring communication reliability.

Functional CharacteristicsCommunication and Control

  • Requires multi-vendor communication software licensing. It can replace Westinghouse WDPF I/O Q cards, and after integration, the process is fully controlled by the advanced VA series algorithm set. By providing a connection between the Terminal Assembly (FTA) and the VA series system, all process signals connected to the Westinghouse system can be accessed and fully integrated into the VA series system for operator display, historical recording, alarming, control, etc.

Migration Strategy

  • The I/A series migration strategy replaces WDPF Distributed Processing Units (DPUs) with VA series control processors/FCMs and provides card-to-card replacement of I/O modules while retaining original process interface wiring and cabinets. The new I/A series system DCS FBM directly inserts into existing Q-Crates to replace Westinghouse I/O Q cards. The Q-cards are removed from the Q-crates, and their terminal assemblies are dismantled. Each device is replaced by the corresponding I/A series system DCS FBM, reusing the original I/O card terminal units installed in front of the I/O cards.

Technical Parameters

  • Measurement Range: Humidity 0-100% RH.

  • Measurement Accuracy: Humidity measurement accuracy is ±2% RH.

  • Operating Temperature: -40°C to 85°C.

  • Output Signal: 4-20mA.

  • Protection Level: IP67.

  • Housing Material: Stainless steel.

  • Power Supply Voltage: 12-36VDC.

Common Faults and Solutions for FOXBORO RH916YY Module1. Communication FailureFault Symptoms

  • The module loses communication with the DCS system, displaying "communication failure" or inability to transmit data.

  • Abnormal indicator lights on the control panel (e.g., communication indicator not on or flashing abnormally).

Possible Causes and Solutions

  • Wiring Issues

    • Cause: Loose or poor contact in communication cables, or cable damage.

    • Solution: Check the wiring between the module and Terminal Assembly (FTA)/control processor, re-plug and secure the interfaces, and replace damaged cables.

  • Communication Protocol Conflict

    • Cause: Incorrect configuration of multi-vendor communication software licensing, or incompatibility with Westinghouse WDPF system protocols.

    • Solution: Confirm that the communication software license is activated, check protocol settings (e.g., baud rate, data bits, parity bit) to ensure consistency with the Westinghouse system; contact FOXBORO technical support to update protocol drivers if necessary.

  • Module Hardware Failure

    • Cause: Damaged communication chip or circuit board.

    • Solution: Replace with the same model module and test if communication is restored; if the new module works, the original module needs repair or disposal.

2. Abnormal Signal Acquisition or OutputFault Symptoms

  • Process signals (e.g., current, voltage) cannot be acquired or output normally, with significant deviation between displayed and actual values.

Possible Causes and Solutions

  • Signal Interference

    • Cause: Interference from surrounding strong electromagnetic devices, or unshielded cables.

    • Solution: Add shielding layers to communication cables and ground them, keep away from interference sources like frequency converters and motors; check good grounding to avoid ground loops.

  • Terminal Assembly (FTA) Failure

    • Cause: Loose, oxidized, or damaged FTA terminals, leading to signal transmission interruption.

    • Solution: Dismantle the FTA to check terminal status, clean oxidized parts or replace the FTA; ensure terminals are tightly connected when re-installing.

  • Incorrect Module Parameter Configuration

    • Cause: Signal range, filter parameters, etc., are set inconsistent with actual needs.

    • Solution: Reconfigure module parameters via the DCS system, such as confirming the output signal range (e.g., 4-20mA), measurement accuracy calibration, etc., and perform on-site calibration if necessary.

3. Power Supply FailureFault Symptoms

  • The module has no power supply, the power indicator is off, or it restarts frequently.

Possible Causes and Solutions

  • Abnormal Supply Voltage

    • Cause: Input voltage exceeds the range (e.g., below 12VDC or above 36VDC), or power supply fluctuates excessively.

    • Solution: Use a multimeter to detect the power supply voltage, ensuring it is within 12-36VDC; install a voltage regulator or UPS if the voltage is unstable.

  • Power Interface Failure

    • Cause: Poor contact in the power interface or internal circuit short circuit.

    • Solution: Check if the power interface pins are bent or oxidized, clean and re-plug them; replace the module if there is an internal short circuit.
