ABB 07 ZE82 R3 CPU Module

This CPU module executes control logic for ABB Advant OCS systems. It manages I/O data and communication tasks for industrial automation. Therefore, this component suits complex process control and manufacturing applications.

Physical Dimensions and Weight Specifications

The ABB 07 ZE82 R3 occupies one standard slot in the Advant rack. Its housing measures 250 mm in depth for backplane connectivity. The module weighs approximately 0.78 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The ABB 07 ZE82 R3 provides one RS-232 port for programming access. A second RS-485 interface supports fieldbus communication with remote I/O. The front panel carries a built-in Ethernet port for plant network connectivity. Hence, users can program and monitor this CPU remotely.

Component Count and Onboard Memory

This CPU module contains one main board with a 32-bit RISC processor. The board holds 1 MB of battery-backed RAM for user programs. You will also find 2 MB of flash memory for non-volatile storage. An onboard real-time clock maintains schedule data during power cycles.

Energy Storage and Power Consumption

The ABB 07 ZE82 R3 draws 350 mA from the 5V backplane supply. A lithium battery retains RAM data for 1,000 days without external power. This battery maintains user programs during prolonged facility shutdowns. Therefore, the CPU eliminates the need for frequent reprogramming after outages.

Processing Speed and I/O Capacity

The processor executes 0.15 microseconds per basic logic instruction. It handles up to 2048 digital I/O points within a single scan. Users can store up to 4096 function blocks in the flash memory. This capacity supports complex automation for large production lines.
