Product Description

Yokogawa SAI143-H63

Overview

The SAI143-H63 is an analog input module supporting 4-20mA signal input, with 16 channels, collective isolation, and HART communication function. The signal cable interface adapter has no explosion-proof function. It complies with ISA standard G3 and operates within a temperature range of -20°C to 70°C.

Functional Features

It enables high-precision analog signal acquisition, accurately converting 4-20mA analog inputs into digital signals for system processing.
Supports HART communication protocol, allowing two-way communication with field instruments compatible with HART to achieve functions like instrument parameter setting and status monitoring.
The 16-channel design enables simultaneous acquisition of multiple analog signals, improving module usage efficiency and system integration.
Collective isolation effectively prevents cross-channel interference and external signal interference, enhancing the module's anti-interference capability and stability.

Technical Parameters

Input signal: 4-20mA
Number of channels: 16 channels
Communication method: HART communication
Isolation method: Collective isolation
Wiring method: Signal cable interface adapter connection
Standard: ISA standard G3
Operating temperature: -20°C to 70°C

Working Principle

Similar to the SAI143-H33, the module integrates a signal conditioning circuit and an analog-to-digital (A/D) conversion circuit. The 4-20mA analog signal output by field sensors first enters the signal conditioning circuit for amplification, filtering, and other processing to adjust the signal to a range suitable for A/D conversion. The A/D conversion circuit then converts the analog signal into a digital signal, which is transmitted via the module's communication interface to the connected control system (e.g., DCS system) for subsequent control and processing.

Common Faults and Solutions1. Abnormal signal acquisition

Possible cause: Mismatch between module range settings and sensor output range.
Solution: Check and reset the module's range parameters.
Possible cause: Sensor failure or wiring issues.
Solution: Replace the sensor and inspect wiring for looseness.

2. HART communication failure

Symptom: Inability to communicate normally with HART instruments.
Possible cause: Incorrect communication cable connection or inconsistent HART address settings between the instrument and module configuration.
Solution: Verify cable connections and reset the address to match the configuration.
Possible cause: Incorrect communication parameter settings (e.g., baud rate, parity).
Solution: Check and correct parameters such as baud rate and parity.

3. Abnormal module indicator lights

Possible cause: Abnormal module power supply.
Solution: Check if the power supply is normal and the voltage is within the module's allowable range.
Possible cause: Internal hardware failure (e.g., circuit short, chip damage).
Solution: Contact professional maintenance personnel or the manufacturer's after-sales service for repair.

4. Fluctuation in analog signals

Possible cause: Unconnected power supply between the analog input module and field sensor, causing common-mode voltage interference.
Solution: Connect the negative terminal of the field sensor to the public M terminal of the module.
Possible cause: Long wiring, poor insulation, or electromagnetic interference.
Solution: Use shielded twisted-pair cables for signal lines, ground the shield layer at the PLC side with single-point grounding, and keep analog signal cables away from strong interference sources (e.g., frequency converters, high-power motors).
