PLC Compatible Batteries
PLC batteries are batteries for control devices in relay circuits. These batteries are used for devices equipped with a relay circuit, such as elevators, escalators, automatic doors and automated machines at factories or other locations. Types such as sequencer replacement batteries and memory backup batteries are available. When a PLC battery is exhausted, the PLC program will be erased in the event of a power failure and a device failure may occur. Dirt such as dust or oil inside the panel may cause fatal damage to the PLC battery; therefore, thorough cleaning and maintenance are required. When used in a hot environment, high-temperature countermeasures must be taken, such as installing a board cooler, or a fan and louver if there are no resources for a cooler.
