Series 94 Electric Actuator Introduction
Description
The Series 94 electric actuators feature a reversing,capacitor run motor, and a
permanently lubricated gear train. These actuators are equipped with integral
thermal overload protection (AC models) with automatic reset, independently
adjustable limit switches, declutchable manual override, visual position indication,
Zytel FR50 enclosure with stainless steel trim, ISO bolt circle, and 2 (two) ½”
NPT conduit entries.
Standard models are offered in 120 VAC, feature a Nema Type 4X enclosure,
and provide up to 300 in-lbs. of output torque.
The DHC-100 is easily mounted with 2 screws and is equipped with removable
screw terminals that provide for easy field wiring.
A simple three button control allows the user to perform a complete set-up from
the unit itself without the need for any instrumentation. The adaptive control
feature of the DHC-100 eliminates the need for any calibration steps. In the
simplest application, only the
closed and open positions need to be set and the
unit automatically and continuously sets all other parameters when placed in the
AUTO mode.
CAUTION: These units are intended to be mounted in an appropriate enclosure
to avoid electrical shocks. High voltages are present on the outside of the unit
when power is applied. AC power should be disconnected prior to any wiring of
these units. A heater and thermostat should be used where condensation may
occur.
Electrical Requirement
CAUTION: Proper voltage must be supplied to actuator/positioner package or
the result could be a damaged positioner, a damaged actuator, or both.
NOTE: To conform to various electrical codes, a green grounding screw has
been installed (on the baseplate) inside of actuator.
The DHC-100 is rated for motors with up to 5A running currents and comes in
three versions to accommodate different voltage applications. The DHC-100 is
rated for 117 VAC
