CO2 Sensor
The CO2 sensor with Humidity & Temp transmitters are designed for environmental monitoring and controlling in industrial, commercial and other buildings. These transmitters can be used for indoor C02, temperature and humidity monitoring. The modbus interface provides easy setup and integration into large systems.Supports Modbus RTU over both the Ethernet port and the RS485 port,supports Bacnet over both the Ethernet port (IP) and the RS485 port (MSTP).
Air Flow Switch
The air flow switch is used to prove air flow in ducts. It has an adjustable trip point with a range from 200 to 1800 FPM (1 to 9.2 m/sec).
The SPDT contacts are rated8A@250VAC.
HVAC Contactors, UL : E246810
Definite purpose contactor is a robust and low cost switching device specifically designed for the heating,ventilating and air conditioning industry.
Power Adapter – PA-12V
The product is AC to DC switching power transfer device,of which the black pluggable connector fits onto most Temco products, or can be taken off to connect to your own devices.
Occupancy Sensor
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.
Pressure Transmitter
Single Ended Pressure Transmitter is a kind of standard and most popular transmitter applied in air and liquid pressure measuring,since a high sensitivity silicon pressure chip is employed in the sensor.</p>
Current Sensor with 0-5VDC output signal
The CS series Current Sensors are solid state transducers for measuring the current in fans, pumps and other HVAC equipments.
Terminal Shorting Bar
The Terminal Shorting Bar (10-pin) lets you run a common conductor across multiple Temco T3 controller terminals. It has a high-temperature ABS cover and can be cut for shorter runs or combined for longer ones.
Digital Storage Oscilloscope
This Digital Storage Oscilloscope offers a 128Kpts sampling depth with up to 250× horizontal magnification after pausing. Its ultra-portable design—just 1/62 the size of a desktop unit—features smooth handling, intuitive controls with 4 buttons and 2 wheels, and durable PC-AB alloy construction with a high-elasticity plush sensor.
Relay Board and Transformer
