The MY2N Relay is a general purpose plug in relay with a LED for power switching applications,built-in diode and surge suppression, test push buttons and more.MY2 = 2-Pole; MY4 = 4-Pole; N = LED; Z = Bifurcated; I = Push-to-Test.
This sensor is used to measure the outside air temperature to allow the DDC system to coordinate the mechanical systems with actual building load conditions, enabling such strategies as free cooling, optimum start/stop, and supply temperature reset. The housing is made from PVC and stainless steel fittings which shield the probe from direct sunlight. There are three thermistor based models, and one RTD version to provide compatibility with the majority of DDC systems.
This passive infrared detector, with high stability, has adopted advanced technology in signal processing and provides extremely high detection ability and anti-error alarm. The detector will detect movement of human automatically when intruder passes through the detection area, and it will send out alarm signal to alarm host if there is movement.This product is suitable for the safety of residential houses, villas, factories, markets, warehouses, and office buildings.
The MRB Mechanical Relay Board is a handy way to mount multiple relays in a tidy package with either 4 or 8 relay models and field selectable coil voltage of 12VDC and 24VAC. There’s a status LED for each relay and a label with writable surface where you can mark the name of each output.
The manifold is designed for use in floor heating systems to regulate heat. It controls flow and return,with the option of connecting up to twelve floor heating circuits.The electro-thermal actuator is designed to control the flow of a hot water pipe to control indoor temperature.
This sensor is used to measure the supply and return temperature in HVAC system. The flange mount design makes it easy to install the sensor in tight quarters. There are several sensor elements to choose from which guarantee compatibility with all popular DDC systems. The probe in the photo is our standard model which is always in stock, it has a 8″ probe and a 120″ cable, and employs either a precision thermistor or platinum film sensor, so field calibration is not required. The 10ft(3m) cable is “Plenum Rated”.
The duct sensor is used to measure the supply and return air temperature in HVAC system. There are several sensor elements to choose from which guarantee compatibility with all popular DDC systems. There is a precision thermistor. The probes are epoxy sealed to prevent moisture from migrating into the probe. Field calibration is not generally required. The standard probe length is 12 inch. Custom probe lengths, wire types and sensor elements are available for large OEM projects. Ask about our plastics & metal manufacturing capabilities for custom housings as well.
The connectors,also called plug-in terminal blocks, provide the wire size from 0.08mm2 to 16mm2. It is available with different pitches from 2.5mm to 10.16mm.You can choose insert direction, contact direction, plug-in direction according to requests.
The Actuator is intended for ON-OFF and floating point controls in HVAC systems. It can easily mount on a 1/2″ round or square shaft with solid screw sets. Angle of rotation is mechanically limited to 90 degree. When the actuator reaches its maximum position, the device will automatically stop. An override lever is provided on the side to manually disengage the gear. Two mechanical stops are provided for extra adjustments.
Motorized series ball valves use bi-directional motor. They are primarily used in central air-conditioning systems, heating systems, water treatment, and the production industry to control the flow of chilled / hot / medium temperature.
