1785-ME16 Functional Description

The Allen-Bradley 1785-ME16 is a memory module designed for use with the PLC-5 series Programmable Logic Controllers (PLCs). It provides 16K Words of non-volatile memory, utilizing Electronically Erasable Programmable Read-Only Memory (EEPROM) technology. This memory module includes a removable jumper for write protection, ensuring the integrity of stored data.

Compatible with various enhanced PLC-5 processors, including models such as PLC-5/11, PLC-5/20, PLC-5/30, PLC-5/40, PLC-5/40L, PLC-5/60, PLC-5/60L, and PLC-5/80, Allen-Bradley 1785-ME16 is a memory module also supports Ethernet-based PLC-5 processors like the PLC-5/20E, PLC-5/40E, and PLC-5/80E. The module is designed for easy installation, although it must be installed without power to the processor. Removing it under power can damage the module and result in data loss.

This Allen-Bradley 1785-ME16 is a memory module serves as a reliable backup memory solution, ensuring that the processor can load the user program automatically upon startup, preventing system downtime caused by the erasure of program data. It can also act as a safeguard to avoid non-operational states during power failures or other disruptions.

The Allen-Bradley 1785-ME16 is a memory module weighs 85.05 grams (3 ounces) and operates within a temperature range of 0° to 60° C (32° to 140° F), with a storage temperature of -40° to 85° C (-40° to 185° F). It has a humidity tolerance of 5-95%, and is resistant to shocks and vibrations, with a 15 g peak acceleration during operation and 3 g during non-operation. The module is certified by CSA, UL, and CE, making it suitable for various industrial applications.
