Physical Dimensions and Component Layout

This module measures 6.0 cm in length and 9.5 cm in width. Its total height reaches 6.5 cm including the connectors. 1SAP150000R0271 weighs just 0.18 kg for DIN rail mounting. You will find 104 discrete components on a six-layer PCB.

Moreover, the module integrates a 470 µF bulk capacitor bank. This bank stores energy for 30 ms during power interruptions. It also filters noise from the 24V DC supply rail.

Processing Performance and Memory

The 32-bit ARM processor executes 1K instructions in just 0.4 ms. This speed supports fast scan cycles for real-time control applications. The 32KB RAM stores ladder logic, function block, and structured text programs. A lithium battery retains this memory for up to 200 days without power.

Communication and Expansion

Two built-in serial ports support RS-232 and RS-485 protocols. These ports connect to programming devices, HMIs, and drives. You can expand I/O using up to 10 local and remote expansion modules. The module also supports up to 32 analog channels.

Typical Application Scenarios

You can deploy 1SAP150000R0271 in ABB AC500 systems for small to mid-sized automation tasks. It also works well for building automation, pump control, and conveyor systems. This CPU handles sequential control, PID loops, and data logging. Its 32KB memory suits applications with up to 128 I/O points.
