ABB 1SAP140100R0170 CPU – 600 MHz ARM, 256 MB RAM

The ABB 1SAP140100R0170 executes control logic for complex automation tasks. This CPU measures 125 mm in width and 110 mm in height. It has a depth of 85 mm, so it fits compact panels easily. The unit weighs 0.48 kg, making DIN rail mounting simple and secure.

Processor Core and Memory Architecture

This CPU contains a 32-bit ARM Cortex-A8 processor running at 600 MHz. The ABB 1SAP140100R0170 includes 256 MB of DDR3 RAM for program execution. It also provides 128 MB of NAND flash memory for persistent data storage. Three separate integrated circuits handle processing, memory, and I/O management. A dedicated real-time clock chip keeps accurate time during operation.

Energy Storage and Power Consumption

The module stores 330 µF of capacitance across its power regulation circuits. This storage prevents resets during brief supply dips up to 8 milliseconds. The ABB 1SAP140100R0170 draws 380 mA at 24V DC under full load. Therefore, total power consumption reaches 9.12 watts during normal operation. It includes a replaceable lithium battery for clock backup during power loss.

Communication Interfaces and Expansion Ports

You will find two independent Ethernet ports on the front panel of this CPU. Both ports support 10/100 Mbps for network redundancy or segmentation. The ABB 1SAP140100R0170 also includes one USB 2.0 port for program uploads. Two RS-485 serial ports support Modbus RTU for legacy device connectivity. A 48-pin expansion bus allows up to 64 I/O modules to attach.

Environmental Tolerance and Programming Features

You can mount this CPU on a standard DIN rail inside any control cabinet. The device operates reliably from -20°C to 60°C ambient temperature. It tolerates humidity levels up to 95 percent without any condensation. The ABB 1SAP140100R0170 stores up to 512 kB of retentive data in non-volatile memory. Consequently, it retains critical values even after a complete power loss.
