What This Model Does
The Model 410B Limit Switch is an electrical accessory for electro pneumatic valve positioners on automated control valve packages. It detects and signals discrete valve end positions, confirming fully open and fully closed states back to the control system or PLC. Designed to operate alongside EAA electro pneumatic positioners as well as rotary and linear actuators, the Model 410B belongs to a switch family that includes the 210, 310, 410A and 510 models, providing plant operators with positive remote travel confirmation.

Problems It Solves
- Control room lacks discrete travel limit signals from control valves running positioners without switches
- Original brand limit switch accessories are on long factory lead times delaying plant commissioning
- Procuring positioners and limit switches from separate suppliers causes delivery coordination delays
- Failed accessories stall plant operations while waiting on lengthy manufacturer warranty repair procedures
- Distributors cannot obtain custom housing colours or OEM nameplates from standard component suppliers
Application Scenarios
- Adding open and closed travel confirmation to a control valve equipped with an electro pneumatic positioner
- Replacing a damaged limit switch on an operating control valve without modifying the actuator mounting
- Building factory assembled actuator and positioner packages for delivery to industrial processing plants

How It Compares With the Alternatives
| Model 410A limit switch | The 410B provides an alternative housing configuration to suit different positioner and actuator mounting arrangements within the 410 series |
|---|---|
| Continuous position transmitter module | The 410B provides discrete open and closed contact feedback, whereas a 4 to 20 mA transmitter reports full continuous travel |
| Model 210 or 310 limit switches | Different enclosure body styles and profiles to suit alternate actuator top works and positioner models |
Fitting and Setting Up This Model
General field procedure. Always follow the datasheet for the exact calibration sequence and any hazardous area requirements.
Mount the Model 410B securely to the valve positioner accessory bracket or actuator mounting surface
Align the switch drive shaft with the positioner feedback mechanism or actuator output stem
Terminate electrical signaling wires to the internal terminal blocks following the site wiring diagram
Cycle the valve actuator to set switch actuation points precisely at fully open and closed limits
Tighten the housing cover to seal internal electrical contacts against surrounding site conditions
Verify signal receipt at the control room PLC before placing the valve loop into live operation
Model 410B Limit Switch FAQ
What is the lead time for Model 410B limit switches?
Regular order quantities normally ship in 2 to 3 days from stock. Large project orders ship in 7 to 10 days.
Is the Model 410B supplied with the positioner or separately?
It can be ordered as a loose spare accessory or supplied pre-assembled with our electro pneumatic positioners.
Can the housing be painted in our company colour?
Yes. Black, blue and yellow are regular colours, and other housing colours are painted to your project specification.
