*In the guard position, the drive mechanism will be active only if the guard input signal is true.
General
The Bristol® 9110-RSR, from Emerson Process Management, is a bi-directional microprocessor based rotary actuator that sets the output of a pneumatic regulator. The output can be adjusted electrically by either discrete (raise/Lower) or analog inputs. These input signals to the “RSR” can be received from remote or local locations either by manual switches or automatic devices.
Description
Series 9110-00A, Remote Set Regulators are trans- ducer devices that use an electrical input signal to set the level of a pneumatic output signal. Depend- ing on the actual models, the output can be config-
ured for a 1-5 Vdc or 4-20 mA dc signal. For the Raise/Lower models, the input can be configured to accept a continuous or pulse incremental dc signal. The pneumatic output of a Remote Set Regulator may
be specified with a 3-15, 3-27 or 6-30 psi output. All
models can operate from pressure supplies up to 100 psi maximum.
The Remote Set Regulator is contained in a weath- erproof, explosion-proof enclosure having a detach- able threaded cover. Removal of the cover provides access to the field wiring terminals and the pro- grammable option switches.
Regulators are factory-furnished for 12 or 24 Vdc supply operation. These voltage ratings are fixed and cannot be changed in the field.
In-line or pipe mounting are offered as for instal- lations. The former uses a ¼ inch rigid pressure line for support, while the latter includes a special bracket for two-inch pipe mounting.
