Space heater
A space heater can increase the internal temperature and keep dry inside actuator to avoid the freezing lubricant and moisture causing actuator failure under low temperature or high humidity. Heater is not recommended if the ambient temperature is higher than 35℃ (95℉). However, when the temperature varies much from day to night or between summer and winter, heater and thermostat are recommended.
Heater thermostat
The option can switch the heater off when the temperature inside the actuator is over 25±5℃ (77±9℉).
Additional limit switches
The standard model equips with the 1st & 2nd switches for fully-open and fully-closed. The option consists of the 3rd & 4th auxiliary switches which provide dry contacts for fully-open and fully-closed.
Analog Output Board
Analog output board is a feedback device which provides an analog output relative to position.
Output signal: 0-20mA, 4-20mA, 0-5V, 0-10V, 1-5V, 2-10V
The picture is based on DC 24V
Modulating control kit
Actuator can be operated according to input signal and provide the output signal for indicator. Input signal : 4-20mA, 1-5V, 2-10V. Output signal : 4-20mA, 2-10V.
OM-1、OM-A、OM-AM
The pictures are based on AC 110/220V
75% duty cycle (IEC standard)
The control kits are suggested when duty rating needs to be exteneded.
OM-1、OM-A、OM-AM：75% duty cycle
The pictures are based on AC 110/220V
Potentiometer unit
The option can be ordered with On/Off actuators.
The selection has 1k or 5k ohm resistance values.
It provides feedback signal for position indicator.
Isolation relay module
when a set of control wire or switch needs to control two or more actuators at the same time, the module is recommended.
OM-1, OM-A, OM-AM
Communication Protocols
Modbus RTU RS485 is available for 110/220VAC,1-PH units.
Local Control Unit
This option contains LOCAL /REMOTE and CLOSE /OFF /OPEN rotary switches. Under LOCAL control mode, the controlled valves or dampers can be driven to open, stop, or close by CLOSE /OFF /OPEN rotary switch.(Available only for on-off/floating control units)
IP rating: IP65
Optional：IP67
Junction Box
Wiring can be done through the optional box, without removing the actuators' cover.
Thermal Insulation Blanket
The combination of quarter-turn electric actuators with a Thermal Insulation Blanket is designed to remove and re-install easily. It makes the actuator run smoothly even in high temperature environment.
Working conditions:
※ Withstand two hours at 250°C (482°F).
※ Withstand one hour at 300°C (572°F).
Available for OM-A, OM-AM, OM-1 to OM-8 on-off/floating units.
SS316
Available for IP67 (OM-1)、IP68 (OM-2~OM-6、OM-F & OM-G).
Please contact your salesperson if outline drawings of SS316 material are required.
