Humidity Ratings:
5% to 95% R.H., Non-Condensing
Electrical Connections:
Field wiring 18 AWG (0.5 mm) to 14 AWG (1.5 mm)
conductors (stranded or solid) and up to 2 - 14 AWG (1.5
mm) conductors (stranded) to screw terminals, located
under the removable access cover.

Square damper shafts: 1/4 to 1/2 in. (6 to 13 mm)
Minimum Damper Shaft Length:
1 in. (25 mm); 3 in.(76 mm) recommended.
Spring Return Timing (at rated load):
< 25 seconds @ -4°F to 130°F (-20°C to 55°C)
< 60 seconds @ -22°F (-30°C)
Cable Specification:
300 V, 75° C, Plenum Rated, 3 ft length from end of access
cover, 18 AWG
Sylk™ Bus:
Sylk is a two-wire, polarity insensitive bus that provides
communications between a Sylk-enabled actuator and a
Sylk-enabled controller. For wiring, the Sylk-enabled
actuator may be mounted up to 200 ft. (61 m) from the
controller; twisted pair wire is recommended for wire runs
longer than 100 ft. (30.5 m). Using Sylk-enabled actuators
saves I/O on the controller and is faster and cheaper to
install since the bus is polarity insensitive.
