ABB 1MRB150022 R0002Y Controller Module

I. Positioning and Applications

• Series Affiliation: Analog input module of ABB AC 500 series PLC, used for collecting analog signals in industrial automation systems and converting them into digital quantities for controller processing.

• Core Functions: Supports high-precision sampling of multi-channel analog signals (such as voltage, current, and temperature signals), suitable for scenarios like process control, power monitoring, and mechanical automation.

II. Technical Parameters and Characteristics

Signal Input Specifications

• Number of Channels: 8-channel analog input (supporting differential or single-ended input).

• Signal Types:

• Voltage: 0-10V, ±10V, 0-5V, etc.;

• Current: 4-20mA, 0-20mA (requires external 250Ω resistor for voltage conversion);

• Temperature Sensors: Resistance Temperature Detectors (RTDs: PT100, PT1000), Thermocouples (TCs: types K, J, T, etc.).

• Accuracy: 16-bit ADC sampling, resolution approximately 0.015% (full scale).

Electrical Characteristics

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

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

• Filtering and Sampling Frequency: Supports software-adjustable filtering (0.1-100Hz), sampling period ≤2ms per channel.

Mechanical and Environmental Parameters

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

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

• Protection Level: IP20, compliant with EN 61131-2 industrial standards.

III. Application Scenarios

Process Control

• Temperature and pressure signal acquisition for chemical reactors;

• Data access for flow and level sensors in water treatment systems.

Power and Energy

• Current and voltage monitoring in substations;

• Power parameter acquisition for photovoltaic inverters.

Mechanical Manufacturing

• Temperature monitoring of machine tool spindles;

• Real-time pressure detection of hydraulic systems.

IV. Interfaces and Wiring

Terminal Block Design

• Adopts detachable terminal blocks (model 1SFA610001R1001), supporting screw or spring terminal connections.

• Typical Wiring Examples:

• Current signal: 4-20mA connected to terminals + and -, with a 250Ω resistor in series;

• Resistance Temperature Detector (PT100): Three-wire connection to dedicated terminals, supporting linearization compensation.

Communication Interface

• Communicates with CPU modules via the AC 500 backplane bus, supporting real-time data transmission (cycle ≤10ms).

V. Configuration and Debugging

Software Tools

• Uses ABB Control Builder AC 500 for configuration, enabling settings for:

• Channel signal types and range;

• Filter parameters and disconnection detection thresholds (e.g., current signal<3.6mA is considered a fault);

• Linearization correction (for non-linear characteristics of TCs and RTDs).

Fault Diagnosis

• Status indicators:

• Power (green): Lights up when power is normal;

• Error (red): Flashes in case of channel faults (e.g., disconnection, out-of-range);

• Sync (yellow): Flashes when communication with CPU is normal.
