ABB 1SBP260021R1001, commercially named 07CR41, is a compact integrated programmable logic controller of the Advant Controller 31 series. It adopts 230 V AC power supply and integrates CPU, power unit, digital inputs and relay outputs. Featuring stable performance and flexible expansion capability, it is designed for logic control and distributed I/O applications in small and medium-sized industrial automation systems.

1SBP is the unified part number prefix for ABB AC31 and Procontic CS31 series controllers. 260021 is the base model code for the 230 V AC controller with relay outputs. R1001 represents the standard hardware revision. 07CR41 is the commercial designation of this AC31 control unit.

This product belongs to ABB Advant Controller 31 series and keeps compatibility with Advant OCS systems. The rated power supply is 230 V AC with an input range from 195 V AC to 264 V AC and frequency of 50 to 63 Hz. The power consumption is about 7 watts under normal operation. It is equipped with 8 channels of 24 V DC digital inputs, which support both sink and source modes. The input current of each channel is no more than 5 milliamperes, and the input delay is between 1 millisecond and 7 milliseconds. There are 6 relay output channels. Each relay contact is rated 2 amperes at 230 V AC and 5 amperes at 30 V DC, with a mechanical service life of more than 100 thousand operations. The processor works at 400 kilohertz. It is equipped with 34 kilobytes program memory and 4.4 kilobytes battery-backed data memory. Two built-in hardware high-speed counters support the maximum input frequency up to 5 kilohertz, and an integrated real-time clock is available. The operating temperature ranges from 0 degree Celsius to 55 degree Celsius, and the storage temperature ranges from minus 40 degree Celsius to 70 degree Celsius. The protection class is IP20 for cabinet installation. The controller can be mounted on standard DIN rail or fixed with screws. The overall dimensions are 102 millimeters by 102 millimeters by 127 millimeters and the weight is approximately 0.8 kilograms. The product has passed CE and UL certifications.

Screw terminals are used for connecting 8 digital inputs, 6 relay outputs and 230 V AC power supply. A RS-232 interface is reserved for program uploading and downloading, ASCII communication and Modbus RTU data transmission. The built-in CS31 bus based on RS-485 can connect up to 31 remote I/O modules, expanding the total I/O points of the system to around 1000. LED indicators display power status, running status, fault information and working state of each channel. This controller is fully compatible with all analog and digital I/O modules of AC31 series to realize system function expansion.

It achieves integrated logic control and can be directly connected with on-site sensors, switches and actuators. The relay outputs provide reliable load driving capacity to control solenoid valves and small electrical equipment. The built-in high-speed counters and real-time clock satisfy the demands of pulse counting and timing control. The CS31 field bus realizes stable long-distance data communication with remote I/O devices without affecting the operation of the main controller. The battery-backed memory can preserve user programs and important data after power failure. It supports channel-level fault detection and real-time status indication, which helps maintenance staff to find and eliminate faults efficiently.

It is widely used for small production lines, assembly equipment and material handling systems in factory automation. It applies to air handling units, fan coil units and environmental monitoring in building automation and HVAC systems. It is suitable for pump control, valve operation and signal monitoring in water and wastewater treatment projects. It also acts as the core control unit for packaging machinery, textile machines, woodworking equipment and other general OEM mechanical devices.

Install the controller vertically on standard DIN rail and reserve sufficient space at the top and bottom for heat dissipation. Keep the device away from intense vibration, moisture and corrosive gases. Use qualified copper wires for wiring and tighten all terminals firmly. Confirm the input voltage complies with 230 V AC rating and never exceed the load limit of relay contacts. Complete programming and parameter configuration via ABB AC31GRAPH or matched configuration software. Check the tightness of terminals and the state of LED indicators regularly during operation. Clean surface dust with dry cloth. Replace the backup battery every 3 to 5 years to ensure the normal operation of memory and real-time clock. Cut off the power completely before disassembly and maintenance. Do not run the device with damaged cables or open housing.
