Allen-Bradley 1785-ME32 PLC-5 EEPROM Memory Module
The Allen-Bradley 1785-ME32 is a 32K-word EEPROM memory module designed for the PLC-5 series. It provides secure, non-volatile backup for control programs and device configurations, ensuring data retention during power loss and enabling easy program transfer between processors in industrial environments.
Product Description
The Allen-Bradley 1785-ME32 serves as a specialized non-volatile storage solution for the PLC-5 processor family. This EEPROM (Electrically Erasable Programmable Read-Only Memory) module primarily functions as a secure backup repository for control logic, configuration parameters, and calibration tables. By utilizing this module, industrial operators ensure that critical application programs remain intact during extended power outages or battery failures, effectively eliminating the risk of data loss in volatile memory.
System integrators frequently deploy the 1785-ME32 to facilitate rapid hardware replacement and disaster recovery. Because the module stores a complete image of the processor’s memory, a new PLC-5 controller can automatically reload the operational program upon installation without requiring a secondary programming terminal. Furthermore, the 32K-word capacity provides ample space for complex instruction sets and extensive I/O mapping. Consequently, the module enhances system availability and simplifies field maintenance in large-scale manufacturing environments.
The hardware is specifically engineered to endure the rigorous conditions of factory floors. Since the module features a wide operating temperature range of 0°C to 60°C and high ESD immunity, it maintains data integrity despite electrical noise or thermal fluctuations. Moreover, the 1785-ME32 supports multiple reprogramming cycles using specific voltage triggers, allowing engineers to update control strategies as site requirements evolve. Ultimately, this module represents a vital reliability upgrade for any legacy PLC-5 control architecture.
