Options Available:
LCP100 Local Control Panel or
external pushbutton
SIL 2 Capable 420 mA position
transmitter or discrete switch
Discrete switch can be configured
for position or alert annunciation
Notes:
Loss of electrical power or pneumatic
supply to DVC6200 SIS exhausts air to valve
‐ Single DO is a common cause failure point
Trigger diagnostics or capture of
demand/reset strokes unavailable since
power to DVC6200 SIS is interrupted during
a demand
BPCS SIS FIELD
Benefits:
SIL3 Capable digital valve controller
‐Redundant DVC6200 SIS and SOV
Wiring to both SOV and DVC6200 SIS
saves I/O
PST with DVC6200 SIS provides
diagnostic coverage
‐Solenoid health monitoring
HART
LC340
0-24 V DC
Example Drawing Only, may require modifications to meet site specific requirements
*Position Monitor AI or DI may reside in SIS or BPCS
**PC with ValveLink software or 475 Field Communicator can be used in lieu of multiplexer
