 Test of coils of
S
olenoid
O
perated
V
alves (
SOV
)

Standard digital hardwired remote control

Interlock controls
 Redundant Modbus RTU communication line
 Local actuator control

Human Machine Interface ( HMI ) with graphic LCD display and non-intrusive, touch-sensitive, pushbuttons
 Multi-language menu,
icon
based
 User friendly navigation in the menu

Local configuration
 Diagnostic functions
 Two microcontrollers working in parallel with cross comparison of operations and diagnostic

Access to menu by password to protect against unauthorized change



Alarm, Warning, Event logger
 Real time clock and battery
 SIL 3 compliance for the SIF functions (ESD Emergency Shut-Down, Line Break and Panic Button)

1oo1, 1oo2, 2oo3 and 1oo3 configuration of analogue input channels with diagnostic

Operating temperature and enclosure suitable for application in field, according to limits reported in the
Classification/Certification paragraph

Separated mounting option
Here below are listed the most important functions available and activated by DVG Automation according to the user
request

PST function ( P artial S troke T est) (see Annex A: PST function)

Line Break ( LB and LB-d ) function (see Annex B: Line Break function)
 HPU ( H ydraulic P ower U nit) control module (see Annex C: HPU control module)

HIPPS ( H igh I ntegrity P ressure P rotection S ystem) function (see Annex D: HIPPS function)

Panic Button (PB) (see Optional panic button paragraph)
 Optional battery (see Optional battery paragraph or Annex B)
Separated mounting option : it allows mounting the ITVC separately from actuator. It is especially useful when the
actuator has to be mounted in a difficult access position, or highly vibrating valve or in excessive high/low temperature
area. The maximum length of cable between ITVC and actuator is
50m
.
SIL features: the specific ITVC SIF functions “ ESD Emergency shutdown ”, Line Break and Panic Button comply
with IEC61508, application “Low Demand mode”. The certificate 43SO00071 is available on request.
Optional battery : if required, ITVC can be equipped (only -20°÷+85°C ITVC version) with a rechargeable lithium-ion
battery, which in case of power supply failure, keeps the ITVC functional, in monitoring mode. The battery is located
on the top of the ITVC enclosure. See Optional battery paragraph or Annex B: Line Break
