Product Description

ABB 500MTM02 1MRB150020R0712 1HDF 930512 X010I. Positioning and Applications

Series Affiliation: Temperature Measurement Module of ABB AC 500 series PLC, used for acquiring temperature signals from industrial sites and converting them into digital values. It is a core component for temperature monitoring in scenarios such as process control and energy management.
Core Functions:

Connects to temperature sensors (TC, RTD, etc.) to achieve high-precision temperature measurement within the range of -200°C to +1820°C.
Supports multi-channel synchronous acquisition, adapting to temperature monitoring requirements of equipment such as heating furnaces, reactors, and HVAC systems.

II. Technical Parameters and Characteristics1. Hardware Specifications

Channel Quantity: 8 analog input channels (supporting mixed configuration of thermocouples or RTDs).
Sensor Types:

Thermocouples: Types K, J, T, E, R, S, B, N, etc.
RTDs: Pt100, Pt1000, Ni100, Ni1000 (supporting 2/3/4-wire connections).

Measurement Accuracy: ±0.1% FS (typical for RTD mode), ±1°C (for thermocouple mode).
Sampling Frequency: ≥100 Hz per channel, supporting high-speed temperature change monitoring.

2. Electrical Characteristics

Power Supply: 24 VDC (±20%), power consumption ≤5 W.
Isolation: Electrical isolation between channels (500 VAC), isolation between power supply and signals, with strong anti-interference capability.
Wiring Method: Removable terminal blocks (spring-loaded or screw-type), supporting hot-swapping (requires system parameter configuration).

3. Environmental Parameters

Operating Temperature: -25°C to +60°C, humidity 5%–95% (non-condensing).

III. Functional Highlights and Technical Features1. Signal Processing and Calibration

Linearization Compensation: Built-in thermocouple and RTD reference tables for automatic temperature-resistance/voltage signal conversion without external calculations.
Self-Calibration Function: Supports hardware zero-point and full-scale calibration, automatically correcting drift errors periodically to ensure long-term measurement accuracy.
Break Detection: Real-time monitoring of sensor loop disconnections, with configurable alarm thresholds and fault output modes.

2. Communication and Configuration

Bus Interface: Communicates with the CPU module via the AC 500 backplane bus, supporting real-time data transmission (update cycle ≤1 ms).
Parameter Configuration: Uses ABB Control Builder AC 500 software to set parameters such as sensor type, filtering time constant, and alarm thresholds.
Data Format: Outputs 16-bit or 32-bit temperature values (engineering units, e.g., °C or °F), supporting floating-point conversion.

3. Safety and Diagnosis

Fault Indication: Integrated LED indicators on the module panel (Power, Run, Error, Channel Fault) for intuitive status display.
Safety Mechanism: Supports output hold (Hold) or preset value (Freeze) during faults to prevent equipment damage from abnormal temperatures.

IV. Typical Application Scenarios

Industry	Application Case	Functional Requirements
Chemical/Pharmaceutical	Reactor temperature control	Multi-channel synchronous monitoring, high-temperature alarm and interlock
Power Energy	Transformer winding temperature monitoring	High-precision Pt100 measurement, fault early warning
Food Processing	Sterilizer/oven temperature balance control	Fast-response thermocouples, multi-stage temperature curve tracking
HVAC	Regional temperature acquisition and centralized monitoring	Compatibility with multiple sensor types, Modbus data upload

V. Interface and Wiring Examples1. Hardware Interface Layout

Power Interface: 2-pin terminal block (+24 VDC, GND).
Sensor Interface: 8 groups of 3/4-pin terminals (each channel independently wired, supporting 2/3/4-wire RTD or thermocouple positive/negative poles).
Backplane Interface: Inserts into the AC 500 system rack to communicate with the CPU module.

2. RTD (Pt100) Wiring Example (3-Wire)

Terminal Label	Connection Method
CH1+	Red wire of RTD (positive pole)
CH1-	Blue wire of RTD (negative pole)
COM1	Black wire of RTD (common)

VI. Comparison with Similar Modules (500MTM01, 500MTM10)

Comparison Dimension	500MTM02	500MTM01	500MTM10
Channel Quantity	8 channels (RTD/TC)	4 channels (RTD/TC)	16 channels (RTD only)
Maximum Accuracy	±0.1% FS (RTD)	±0.2% FS (RTD)	±0.05% FS (RTD)
Communication Interface	Backplane bus	Backplane bus	Backplane bus + Ethernet
High-Speed Sampling	Supported (100 Hz/channel)	Supported (50 Hz/channel)	Supported (200 Hz/channel)
Application Scenarios	Medium-scale temperature monitoring systems	Small equipment temperature measurement	Large high-speed temperature acquisition systems

VII. Configuration and Debugging Essentials1. Software Tools

Completed via Control Builder AC 500:

Hardware configuration (defining module address, channel type);
Temperature range mapping (e.g., -50°C~+150°C corresponding to digital values 0~32767);
Alarm configuration (upper limit, lower limit, rate-of-change alarm).

2. Calibration Process

Perform zero-point calibration (connect to a 0°C reference source) and full-scale calibration (connect to a known temperature point) via software during initial use or periodically (recommended annually).

3. Fault Troubleshooting

If the Error light is on, check the channel fault code via software (e.g., 0x01 indicates disconnection, 0x02 indicates out-of-range).

VIII. Conclusion

As a general-purpose temperature measurement module in the AC 500 series, ABB 500MTM02 meets the requirements of medium-scale industrial temperature monitoring with high compatibility, accuracy, and reliability. Its core advantages include:

Flexible Adaptation: Supports multiple thermocouple/RTD types, compatible with different sensor selections.
High-Precision Measurement: Built-in reference tables and self-calibration mechanism ensure strong long-term stability.
Convenient Maintenance: Hot-swappable design and fault diagnosis functions reduce downtime.
