ABB 1SAP121000R0071 – Processor Module for Control Applications

The ABB 1SAP121000R0071 serves as the central processing unit for automation systems. This module measures 130 mm in width and 110 mm in height. It weighs approximately 0.52 kg, so installation remains straightforward. You will find one 32-bit processor running at 300 MHz on this board.

Internal Architecture and Memory Configuration

This processor module contains four separate integrated circuits on its main board. One chip handles arithmetic logic, while another manages I/O scanning. The third chip stores firmware, and the fourth handles communication protocols. The ABB 1SAP121000R0071 includes 64 MB of DDR2 RAM for program execution. It also provides 32 MB of flash memory for persistent data storage.

Energy Storage and Power Requirements

The module stores 220 µF of capacitance across its voltage regulation circuits. This storage prevents resets during brief supply interruptions of up to 10 milliseconds. The ABB 1SAP121000R0071 draws 320 mA at 24V DC under full load. Therefore, total power consumption reaches 7.68 watts during normal operation. It contains no internal battery for real-time clock backup.

Communication Interfaces and Expansion Ports

You will find two Ethernet ports on the front panel of this processor. One port supports 10/100 Mbps for network connectivity. The other port serves as a dedicated service interface for configuration. The ABB 1SAP121000R0071 also includes one RS-485 serial port for Modbus RTU. A 24-pin expansion connector allows additional I/O modules to attach.

Environmental Tolerance and Mounting Details

You can mount this module on a standard DIN rail inside any control cabinet. The device operates reliably from -25°C to 70°C ambient temperature. It tolerates humidity levels up to 95 percent without any condensation. The ABB 1SAP121000R0071 withstands vibration up to 2g from 10 to 150 Hz. Consequently, it suits harsh industrial environments like power plants or factories.

Below is a complete summary of its technical specifications.

The ABB 1SAP121000R0071 replaces older processors in AC500 PLC systems directly. You do not need any special adapters or additional mounting hardware. This module also supports firmware updates via the service Ethernet port. Therefore, you can keep your control system current without removing the processor.
