ABSTRACT:
A memory cartridge for convenient manual attachment of a RAM memory with battery back-up to an I/O module in a programmable controller system is inserted through an opening in a side cover of the I/O module and connected to a main circuit board. The housing has a pair of clip members on opposite ends with grooves running transversely across the ends to receive the edges of mounting flanges extending inward at upper and lower ends of an opening in the side cover. The clip members are yieldable in the longitudinal direction of the cartridge housing--to squeezed between a thumb and fingers of one hand--and when the cartridge is inserted through the side cover opening to a certain depth, the clip members are released to secure the cartridge between the mounting flanges.
