ABB 07 KR 240 R1 PLC Control Module for Procontic Systems

The ABB 07 KR 240 R1 serves as the central processing unit for Procontic controllers. You can install this module into the main rack slot of any Procontic system. It executes user logic and manages all I/O data exchange. This control module suits small to medium-sized automation tasks reliably.

Technical Specifications and Hardware Architecture

This PLC control module measures 130 mm in height. Its width reaches 65 mm, and the depth equals 110 mm. The ABB 07 KR 240 R1 weighs approximately 0.45 kilograms. A single internal main PCB contains the microprocessor and memory circuits. The module includes one lithium battery for program and data retention. This battery preserves user logic during extended power-off periods. A 40-pin edge connector interfaces directly with the Procontic backplane. Two 9-pin D-sub ports provide programming and diagnostic access.

Memory Capacity and Processing Performance

The ABB 07 KR 240 R1 provides 32 KB of user program memory. It also includes 2 KB of retentive data storage. The module executes 1000 ladder logic instructions in just 5 milliseconds. Consequently, this speed handles most sequential and combinational control tasks. The lithium battery offers three years of typical service life. A front-panel LED signals low battery voltage well in advance. The module supports up to 128 local I/O points without expansion.

Programming and Diagnostic Features

You must insert this module into slot zero of the Procontic rack. Transitioning to programming, use a handheld terminal or PC software via the D-sub port. The module includes a three-position keyswitch for run, stop, and program modes. Three front LEDs show power, run, and fault status clearly. A built-in watchdog timer resets the processor on software hangs. The operating temperature range sits between 0°C and 55°C.
