Honeywell MU-PAIH02 51304489-100 High Level Analog Input Module

Product Introduction

The Honeywell MU-PAIH02 51304489-100 High-Level Analog Input Module is a critical component of Honeywell’s TDC 3000 and TPS (TotalPlant Solution) Distributed Control Systems (DCS). Designed to interface with high-level analog signals from process field devices, the MU-PAIH02 offers reliable, accurate, and noise-resistant input acquisition for control and monitoring functions in mission-critical environments.

As part of the Process Manager family, the MU-PAIH02 is engineered to handle analog inputs such as 4–20 mA and 1–5 V signals, typically originating from sensors, transmitters, and analyzers. With Honeywell’s signature emphasis on fault tolerance and diagnostic capability, this module supports advanced signal processing, system diagnostics, and integration with fault-tolerant I/O backplanes for maximum availability in continuous process industries.

Product Specifications

• Redundancy Ready: Integrates seamlessly into fault-tolerant I/O chassis to ensure zero downtime.

• Accurate and Stable Readings: High precision even under varying load and temperature conditions.

• Simplified Maintenance: Hot-swappable design reduces the need for system shutdowns during servicing.

• Reliable Isolation: Galvanic isolation prevents ground loops and protects sensitive control circuits.

FAQ

1. What types of analog signals are supported by the MU-PAIH02 module?
   The module supports 4–20 mA, 0–20 mA, 1–5 V, and 0–5 V input signal types.

2. Is there electrical isolation between channels?
   Yes, each channel is individually isolated to prevent cross-talk and ground loop interference.

3. Can the module detect a broken sensor loop?
   Yes, it has built-in diagnostics for open loop and out-of-range conditions.

4. What is the resolution of each analog input?
   The input resolution is typically 12-bit, providing fine signal granularity for control purposes.

5. Does the module support HART communication?
   No, MU-PAIH02 is designed for standard analog signals and does not natively support HART protocol.

6. Can the module be replaced while the system is powered?
   Yes, hot-swap is supported when used in a redundant or fault-tolerant I/O chassis.

7. How frequently does the module update input values?
   Input channels are typically scanned every 500 milliseconds.

8. Is the module suitable for safety-critical systems?
   It can be used in high-reliability environments, but safety integrity level (SIL) must be validated at the system level.

9. Does the module require external power?
   No, power is supplied through the IOTA/backplane connection.

10. Can multiple MU-PAIH02 modules be used in a single system?
    Yes, multiple modules can be installed to scale analog input capacity as required.
