Switch ST

Switch-ST is extremely easy to program using the display and the encoder on the front panel.

Switch-ST is equipped with a system of By-pass passive (Relay) able to “bypass” directly to the control circuit and switching, connecting the main entrance (MAIN) at the output (OUT) in the event of failure of the device extended or in case of power failure (unless this option Back-Up).
Switch-ST is equipped with an auxiliary output stereo, on RCA pin connectors to allow any connection to recording devices.
Switch-ST is able to accept external commands normally closed or normally open, inputs are optically isolated.
Switch-ST, trough the Logic I/O port, provides commands optocoupled output that repeat the status of the switches.
