14 Input output signal

14.1 Digital Input

The REVO CL 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 M2)

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

14.1.2 Configurable Input (Terminal 4 of M2)

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 CL thyristor unit has 1 relay output on terminal 14-15-16 of terminal blockM1(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 ,SCR and Current limit alarm are active.
 SCR and Current limit alarm are active.
 HB and Current limit alarm are active.
 Only Current Limit alarm is active.
 HB and SCR alarm are active
 Only SCR alarm is active.
 Only HB alarm is active.
14.3 Analog Input
The REVO CL thyristor unit has 2 analog inputs
The primary input for the analog setpoint is configurable (0÷10V, 4÷20mA, ecc):, the secondary input
for the Current Profiler or Ext. Feed-Back (0÷10V).

14.3.1 Primary Input

The primary input is already configured in line with customer requirements that are defined in the Order
Code. The Order Code is written on the identification label.
However, if you wish to change the primary input (ex. from 0÷10V to 0÷20mA, 4÷20mA).
see par. Primary Analog Input Configuration 18.3. for details
