Honeywell 620-0024 Memory Module 24k

The 620-0024 is a dedicated Memory Module designed by Honeywell for the IPC 620 Programmable Controller System. It provides a storage capacity of 24K words to expand processor memory, enabling the system to execute complex ladder logic programs and large-scale industrial control applications.

Memory Architecture and Compatibility

The module utilizes read/write CMOS memory, allocating one word per ladder logic element for efficient program execution. It requires a system-level battery backup to maintain data integrity and is explicitly compatible with Honeywell 620-25 and 620-35 processors.

Mechanical and Environmental Parameters

The unit measures 1.1 in x 9.4 in x 6.3 in (2.8 cm x 23.9 cm x 16.0 cm) and weighs 0.3 kg. It is rated for operation across a temperature range of 0 deg C to 60 deg C and a storage temperature range of -40 deg C to +85 deg C.

Installation Guidelines

Always shut down system power before handling the module to prevent electrical damage. When mounting into the rack, ensure the component side faces left, and install the module into Card Slot C for 620-25 processors or Card Slot E for 620-35 processors. Secure the assembly using the integrated captive screw or latch.
