1785-ME16

The Allen-Bradley 1785-ME16 PLC 5 Memory Device has a memory of 16 K words. This module is an EEPROM module. This module has user-modifiable ROM which can be erased and reprogrammed repeatedly. The 1785-ME16 can be used as a backup device. The operating temperature of the 1785-ME16 is 0-60 °C (32-140 °F). The storage temperature is -40-85 °C (-40-185 °F) and the relative humidity range is 5-95% without condensation. The Allen-Bradley 1785-ME16 has an operating shock of 30.0 g (3 pulses, 11 ms). The nonoperating shock of this module is 50.0 g (3 pulses, 11 ms). The 1785-ME16 also follows some Electromagnetic Compatibility (EMC) standards. The Allen-Bradley 1785-ME16 has passed EN 50081-2 EMC - Generic Emission Standard, Part 2 - Industrial Environment regulations. If you are connecting or disconnecting the cable with power applied to this module or any device on the network, an electrical arc can occur and this can cause damage or injury.

The Allen-Bradley 1785-ME16 is a Memory Module with PLC-5 Programmable Logic Controllers (PLC). This module provides a removable, non-volatile memory amounting to 16K Words. The embedded memory is of Electronically Erasable Programmable Read-Only Memory (EEPROM). It features write protection through the removable jumper installed at the side of the module.

This module is compatible for use with enhanced PLC-5 processors 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. It also supports Ethernet PLC-5 processors such as the PLC-5/20E, PLC-5/40E, and PLC-5/80E.

To install this module, the processor must be without power. Similarly, it does not support removal under power. This may damage the module and erase the contents of the device. It may be configured to serve as backup memory, preventing the processor from entering non-operational state due to erasure of the user program. It may be set to automatically load the user program at every processor start-up.

The 1785-ME16 weighs 85.05 grams or 3 ounces. It has an operating temperature requirement of 0° to 60° C (32° to 140° F) and storage temperature of 40° to 85° C (-40° to 185° F) with a relative humidity of 5 to 95% (without condensation). It has an operating shock of 15 g peak acceleration at 11 ms duration and non-operating shock of 3 g peak acceleration at 11 ms duration. It also has a vibration rating of 2 g peak acceleration at 10-500 Hertz. It carries certification from CSA; CSA Class I, Division 2 Groups A, B, C, D; UL and CE.
