ABB 07 PS 62 R1 Program Memory Module

This program memory module stores user logic for ABB Procontic control systems. It provides non-volatile storage for automation programs and configuration data. Therefore, this component enables quick system recovery after power interruptions.

Physical Dimensions and Weight Specifications

The ABB 07 PS 62 R1 occupies one standard slot in the Procontic rack. Its housing measures 250 mm in depth for backplane connectivity. The module weighs approximately 0.32 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The ABB 07 PS 62 R1 provides a 20-pin backplane connector for power and data. A separate front panel carries no external field wiring connections. The module includes a memory protect switch to prevent accidental overwrites. Hence, users can secure critical programs against unauthorized changes.

Component Count and Memory Architecture

This program memory module contains one main board with EPROM chips. The board holds 64 KB of non-volatile storage for user programs. You will also find an onboard write-protect circuit for data security. An LED indicator shows when the module actively accesses memory.

Energy Storage and Power Consumption

The ABB 07 PS 62 R1 draws 50 mA from the 5V backplane supply. The EPROM version requires no battery for data retention. The module contains no internal capacitors or backup cells. Therefore, it retains all programs indefinitely without any external power source.

Installation and Operational Features

Users can insert or remove this module without powering down the system. A polarized connector prevents reverse insertion into the rack socket. The module includes a recessed area for a removal tool. This design simplifies program updates during short maintenance windows.
