ABB 500ITM02 1MRB150021RO116 1HDF930712X010 Temperature Measurement Module

Channel Quantity: 8 analog input channels, supporting differential or single-ended input.

Sensor Types:

Accuracy: ±0.1% (RTD), ±0.5℃ (TC, under 25℃ reference temperature).

Temperature Range:

Power Supply: 24VDC (±20%), power consumption ≤5W.

Isolation: Electrical isolation between channels (500V AC/1min), with strong anti-interference capability.

Mounting Method: 35mm DIN rail mounting, supporting vertical/horizontal installation.

Operating Temperature: -25℃ ~ +60℃, humidity 5%~95% (non-condensing).

Supports open-circuit detection, short-circuit detection, and sensor fault alarms (such as over-temperature, out-of-range).

Built-in cold junction compensation (for thermocouples) and linearization algorithms to reduce measurement errors.

Real-time communication with AC 500 CPU via backplane bus, data update cycle ≤1ms (full channels).

Supports conversion of temperature data to engineering units (℃/℉) and direct mapping to PLC memory addresses.

Each channel can be independently configured for sensor type, filtering parameters (low-pass filtering), and alarm thresholds.

Supports hot-swapping, allowing module replacement without power-off for easy maintenance.

In chemical reactors, monitor material temperature via Pt100 RTD and real-time control heating/cooling systems.

In metallurgical furnaces, collect furnace temperature data using Type K thermocouples and link with PLC for closed-loop temperature control.

In air conditioning systems, monitor supply/return air temperature to optimize energy consumption control.

In thermal pipe networks, achieve heat distribution and leakage detection through multi-point temperature acquisition.

Real-time temperature monitoring of food processing equipment (such as sterilizers) to ensure process parameters meet standards.

Temperature data acquisition and recording for freeze dryers and incubators in the pharmaceutical industry.

Signal Interface: 20-pin terminal block, supporting screw or spring terminal connections for sensor cables.

Communication Interface: Backplane bus interface, inserted into the CPU rack or expansion rack of AC 500 series PLC.

Pt100 (4-wire): Connect the 4 wires of RTD to the module's measurement terminals (e.g., A+, A-, B+, B-) without additional reference resistors.

Type K Thermocouple: Positive pole connected to "+" terminal, negative pole to "-" terminal; cold junction compensation terminals (C+, C-) need to connect compensation wires or ground.

Use ABB Control Builder AC 500 for module configuration:

Indicator Lights:

Fault Troubleshooting: View channel status logs via Control Builder to locate issues such as open circuits and over-temperature, and check wiring and sensor compatibility.

Strong Compatibility: Supports all types of temperature sensors, adapting to measurement needs in different industrial scenarios.

Accuracy and Reliability: Electrical isolation design and built-in compensation algorithms ensure stable measurement in harsh environments.

Flexible Configuration: Independent channel parameter setting and hot-swapping function facilitate system expansion and maintenance.
