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 above 35℃/95℉. However, when the temperature varies much from day to night or between summer and winter, heater and thermostat (25±5℃/77±9℉) are recommended.
Heater thermostat
The option can switch the heater off when the temperature inside the actuator is over 25℃/77℉.
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.
Current position transmitter
The option can provide 4-20mA output signal for position indicator and etc.
The picture is based on DC 24V
Modulating controller
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
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.
