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
