Accessories and Ordering Information:
 Crank Arm Kit, OS-No. DIAM-CRK-01
 Self Centering Shaft Adapter
 Anti-Rotation Bracket
TYPICAL SPECIFICATION
Spring return actuators shall be direct coupled type requir-
ing neither crankarm nor linkage and be capable of direct
mounting to a jackshaft of up to 3/4 in. diameter. The actua-
tor shall connect to the shaft using a removable output hub
with a self-centering shaft coupling. This coupling shall
provide concentric mounting and include an integral
adjustable range-stop mechanism.
The actuator shall provide floating and proportional 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. Some proportional and floating control
models shall provide a feedback signal. Floating actuators
shall have a rotation direction control switch accessible on
the cover.
All spring return actuators must be designed for either
clockwise or counterclockwise fail-safe operation with a
continuously engaged mechanical spring. This spring must
return the valve or actuator to a fail-safe position within 25
seconds of power loss.
All actuators shall be designed for a minimum of 60,000
fullstroke cycles at rated torque and temperature, 60,000
spring return cycles and 1,500,000 repositions. Run time
shall be constant and independent of: load, temperature,
and supply voltage (within specifications). All actuators
shall be UL60730 and cUL (CSA22.2) listed, have a five year
warranty, and be manufactured under ISO 9001 Interna-
tional Quality Control Standards. Actuators shall be as
manufactured by Honeywell.
Sylk™ Bus:
Sylk is a two-wire, polarity insensitive bus that provides commu-
nications between a Sylk-enabled actuator and a Sylk-
enabled controller. For wiring, the Sylk-enabled actuator may
be mounted up to 200 ft. (61m) from the controller; twisted
pair wire is recommended for wire runs longer than 100 ft.
(30.5m). Using Sylk-enabled actuators saves I/O on the con-
troller and is faster and cheaper to install since the bus is
polarity insensitive.
