TYPICAL SPECIFICATION
Spring return actuators shall be direct coupled type requiring neither cran-
1-1/16
(27) karm nor linkage and be capable of direct mounting to a jackshaft of up to 5/8
in. diameter. The actuator shall connect to the shaft using a removable output
hub with a self-centering shaft coupling. This coupling shall provide concen-
tric mounting and include an integral adjustable range-stop mechanism.
4-9/16
(116) 6-61/64 The actuator shall provide two-position, floating, proportional, or Sylk bus
(177) control. Proportional control refers to direct acceptance of 0-10 Vdc, 2-10 Vdc,
or (with addition of a 500 ohm resistor) a 4-20 mA input signal. Proportional
5-27/32
(148) and floating control models shall provide a feedback signal. Sylk-enabled
models provide control and feedback via communication between the actua-
tor and Sylk-enabled controller. Actuators shall provide wiring terminals
located within an integral access cover with conduit connections. Propor-
tional and floating actuators shall have a rotation direction control switch
accessible on the cover.
All spring return actuators must be designed for either clockwise or counter-
clockwise fail-safe operation with a continuously engaged mechanical spring.
This spring must return the valve or actuator to a fail-safe position within 25
2-1/64 seconds of power loss.
(55)
All actuators shall be designed for a minimum of 60,000 fullstroke cycles at
rated torque and temperature, 60,000 springreturn cycles and 1,500,000 repo-
1 CABLE AND STRAIN
sitions. Run time shall be constant and independent of: load, temperature,
RELIEF ON SELECT
1 and supply voltage (within specifications). All actuators shall be UL60730 and
MODELS ONLY. 36 (914) M28945A cUL (CSA22.2) listed, have a five year warranty, and be manufactured under
ISO 9001 International Quality Control Standards. Actuators shall be as manu-
factured by Honeywell.
