Software Supported Configurations
• By means of Hand Held Terminal (HART)
• PC by means of VALcare Software
• PC among others by means of PC20/ PC50 /IFDC
• I/A Series System and other DCSs
• Depending on the version, configurations can be
achieved by a non-contact, protocol-independent
infrared interface by means of IRCOM

Spool Valve Amplifier for Single and Double Acting
Application
Spool valve amplifier as option for the SRD991 can be
used with double acting actuator and also with single
acting actuator
In case of single acting application, one of the pneumatic
output must be closed:
• If y1 is used, y2 is closed and failure handling for Electric
power failure and Failure of electronics becomes y1=zero
• If y2 is used, y1 is closed and failure handling for Electric
power failure and Failure of electronics becomes y2=full
air supply
