The SMS-22 is an alarm monitoring and control system by JRCS (Japan Radio Electric MFG). The SGP-640-A is its LCD graphic terminal: a 24 VDC display unit that presents alarms and measured values from the system’s I/O units. A memory card slot on the rear holds the screen/configuration data. JRCS has announced the discontinuation of SMS-22, SMS-32, SMS-22-K and SMS-32-K, with SMS-55 as the replacement model, which makes used and refurbished SGP-640-A terminals important spare parts.
