Section 4: Device Description
Device Description
POWER SUPPLY
The IMVS2000v2 accepts a wide range power supply:
• from 19.2 Vdc to 57.6 Vdc (24 Vdc -20% to 48 Vdc to +20%).
SOVs CIRCUITS
The IMVS2000v2 can manage two independent (isolated) circuits for controlling up to two
external Solenoid Valves (SOVs).
Each circuit has its own dedicated power supply (SIS) that through a relay is used to control the SOV.
DIGITAL INPUTS (Opto-isolated)
The IMVS2000v2 is provided with three opto-isolated Digital Inputs (DI) for controlling the
Solenoid Valves (SOVs) and for launching a PST test.
DIGITAL OUTPUTS (Solid State Relays)
The IMVS2000v2 is provided with six isolated (solid state relay) Digital Outputs (DO):
• OPEN
• CLOSE
• COMMON FAILURE ALARM
• PST IN PROGRESS
• PST PASSED
• PST FAILED
AUTO-DIAGNOSTIC
The IMVS2000v2 monitors the status of its internal sensors (pressure and position).
ADDITIONAL BUS CARDS
The IMVS2000v2 has the possibility to use one of the following optional Bus Card:
• HART Card (HART 7)
• MODBUS Card (MODBUS-RTU)
4.2 Identication of the Main Parts
In this section, only the main parts of the IMVS2000v2 are shown. Refer to the “PARTS LIST”
paragraph, for a full list of the IMVS2000v2 parts.
The IMVS2000v2 device is composed by three main parts:
a. a base cover with a glass window to display a mechanical visual indicator,
b. a local interface cover with three push-buttons and a glass window to
show the indication of an internal display,
c. a sensor manifold to allocate the pneumatic/hydraulic sensors with
relevant connections and cable entries for electrical wirings.
