14 Input output signal

14.1 Digital Input

The REVO M thyristor unit has 2 digital inputs opto-isolated to 24Vdc 5 mA.
You can activate the inputs with the internal supply or with an external source for example the PLC.

14.1.1 Start/Stop (Terminal 3 of M1)

This is the start command (Enable) of the REVO M.
If you Remove the Start command the REVO M thyristor unit will be stopped and the output will return
at zero.

14.1.2 Configurable Input (Terminal 4 of M1)

This digital input is configured by the parameter  and could perform different functions:
 Enable:
This function forces the output at zero.
 Feed-Back Selection:
With this function, when you active the input, the feed-back setted in the parameter  change in
Voltage Feed-Back (V).
 Analog/Digital Setpoint(Local/Remote):
With this function, when you active the input, the setpoint reference change from Analog input to
Digital value in bumpless mode, setted in the parameter  . The parameter SP is not stored in
memory.
 Change Firing type:
With this function, when you active the input, the Firing type setted in the parameter  change in
Phase Angle PA.
14.2 Digital Output
The REVO M thyristor unit has 1 relay output on terminal 9-10 of terminal block M1(Max 500mA,
125Vac). The functionality of this output cane be setted with the parameter 
This digital output can be configured in order to activate itself after that one of these alarms occours:
 HB and SC alarm are active.
 Only HB alarm is active.
 Only SC alarm is active.
See par. "15.3 Relay Jumper configuration on JP3" to set the Relay NC or NO (Normally close-
normalmente open).
