- The 1747-L514 may be installed with an optional non-volatile memory. Non-volatile memory are in the form of Electrically Erasable Programmable Read-Only Memory (EEPROM). Compatible EEPROM are 1747-M1with 1K User Words EEPROM, 1747-M2 with 4 K User Words EEPROM with a 1747-M5 memory module adapter socket. EEPROM modules may be used to burn programs stored in the built-in memory which is a Random Access Memory (RAM). By burning program to the non-volatile memory, user program may be automatically loaded once the controller is power cycled.
It uses the 1747-BA lithium battery assembly with a 30-minute capacitor life and a lithium battery with a 2-year lifespan for backup power for the standard RAM. The 1747-L514 has a maximum bit execution time of 4µs and an overall module scan time of 8ms/K. During a temporary power loss, the program scan on the module can take from 20ms to 3s depending on the power supply that is loading. It comes with a base DH-485 communication capability which can only act in a slave capacity (Receiving) in the programming channel. The 1747-L514 has an ambient operating temperature range of 0-60°C (32-140°F) at 5-95% non-condensing relative humidity range, and it is designed to sustain an operational shock of 30G, and a vibration of 2.5G at 57-2000Hz. The 1747-L514 is C-UL, UL, and CE-certified, and it offers a NEMA standard ICS 2-230 industrial noise immunity.
