9.3 Input and Output of ITVC
This paragraph lists the inputs and outputs available in the ITVC electronics. These I/O’s are collected in two terminal
blocks, one terminal block is available to user, for connection of signals with the control room, the other one is available
for connection of the actuator signals (Solenoid operated Valves, transmitters, etc.). The electrical features of the I/O’s
are described in the
INSTALLATION
chapter
I/O’s available on
user

9.4 Status signalling
Output status of system ITVC-H/PCU-Actuator is available:
Locally, by the HMI, Human Machine Interface, described in the chapter ITVC HMI
remotely by
o
1 Monitor relay: it summarizes the Alarm and MRT alarm status
o
4 latched, output relays. The condition to switch of each relay can be set by the configuration options
9.5 BUS control
2 independent RS 485, Modbus RTU communication lines, are available to control the ITVC by a Modbus
master station.
