The RS232 Remote Control Unit (RS232 RCU) is a general purpose serial to latching relay dry contact closure converter. It accepts simple ASCII text based RS232 serial commands to control three latching relay dry contact closure outputs. The RS232 RCU's latching relay dry contact closure outputs are sequenced to provide a "make before break" function. The RS232 RCU also continuously monitors the status of three pairs of external dry contact closure inputs. Status LEDs on the front panel continuously display the connection state of these external dry contact closures, and the user can additionally query their status via the RS232 serial interface.
