Anti-condensation 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℉).
Auxiliary 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
The option can provide 4-20mA output signal for position indicator and etc.
OM-2~OM-13,OM-F,OM-G The picture is based on AC 110/220V
Modulating control
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-2~OM-13,OM-F,OM-G
The pictures are based on AC 110/220V
Extended duty cycle kit, (including motor, IEC standard)
The option is suggested for higher starting frequency.
OM-2~OM-8：75%duty cycle
The picture is based on AC 110/220V
Potentiometer
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.
OM-2~OM-13（1KΩ or 5KΩ）
Local control unit
The option can be used in filed control. It provides Local/Remote selection switches and Open/Close selection switches. It is available for OM-2 to OM-13, OM-F, OM-G, OM-H and must be ordered with actuators.
Torque switches
The option can provide over-load protection. It is available for OM-2 to OM-13,OM-F,OM-G actuators, and must be ordered with actuators.
Time Delay Controller
The option can adjust the actuator speed (running time) from standard to 30s, 60s and so on (Max. 200s) according to user’s need. It is available for OM-2 to OM-13, AC 220V,1-PH and OM-2 to OM-8, 110VAC actuators.
Chain wheel drive
The option can convert the hand-wheel override to a chain driven override in application of actuator mounted at a distance above the floor. It is available for OM-2 to OM-13, OM-F, OM-G, OM-H.
Junction box
The option can be connected all wires by the user without removing actuator cover and it is available for OM-2 to OM-13,OM-F,OM-G, OM-H
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.
Communication protocols
Modbus RTU RS485
vailable for:
※OM-2 to 6, F, G, H, 110-120VAC/1-PH, 30% duty cycle
