Foxboro Eckardt Intelligent Positioner SRD991FAANR-V12

The SRD991 consists of a basic device with a digital controller that supports different communication

protocols (or also simply 4-20 mA input). Into this basic device, additional equipment can be built such as

plug-in cards for electrical input/output signals, position feedback and pressure sensors.

The pneumatic part is available in different versions (single / double acting or spool valve). For very large

actuators, boosters with increased air capacity can be flanged on. Also, different manifolds for connection of

gauges can be flanged on. For the pneumatic screw connections, we offer different threads in the housing

and adapters.

For use in hazardous areas, there are approvals according to ATEX / IECEx, FM, CSA, EAC, NEPSI, etc.

The device can be configured locally by means of push buttons and LCD / LED, or with PC + EDC82

Modem connected to the service plug of the SRD991. By means of communication, the device can be

configured remotely via FDT/DTM.

A large variety of attachment kits for all common valves and actuators are available. The list

“AttachmentKits.pdf” is updated continuously and can be found on the Internet.

For high temperature or high vibration application, we recommend to mount the SRD991 remotely and not

directly on the valve. For this, use the potentiometer unit (like the SRI990 - TXQxxxxx - H).

Please consult TI EVE0105 R for specifications.
