General Purpose Relay
Featuring top-mounted terminals, this enclosed power relay has a flange-type mounting bracket for mounting in panels and ductwork. These relays are good as status points for high voltage circuits, connect the coil to the high voltage equipment and wire the dry contacts directly into the low voltage side of any of the controllers and thermostats on this site. The spade terminals make for easy troubleshooting in the field and good isolation of high & low voltage circuits.
High power switching capacity for motors and other inductive loads. The standard stocking item is the 20 amp version though we have 30 and 40 amp available as well as other variations shown in the datasheet, by request.
Differential Air Pressure Switch
PSN40-400A differential pressure switch is used for fan status and dirty filter applications. A knob with pressure values on it allows the setpoint to be adjusted visually in the field. The plastic duct probe tubes, flexible silicon tubing and the mounting screws are included with all models.
RTS3 Flush Mount Hidden Room Temp
The room temperature sensor provide precision room temperature sensing in a discreet button form factor for all popular DDC systems.
Probe Temperature Sensor
This Probe Temperature Sensor comes standard with a 15mm Stainless Steel Temperature Sensor. This sensor is a 10K Thermistor, with an industry standard Type 2 curve.Connected to the end of the Sensor is 2 UL2468 26/2CAWG 105°C Black Wires with tinned ends.
RTS Wall and Bead Sensors
The room sensors are used to provide reliable, accurate temperature readings in surface-mount room environments, Energy Management Control Systems, compatible with all the leading control systems.They feature a standard plastic ventilated enclosure.
Tamper Proof room temperature sensor
The tamper proof room temperature sensor with Torx security screws designed for use with building automation systems in commercial buildings, hospitals, museums or other facilities requiring accurate measurement of room temperature. This sensor can be directly mounted to drywall or an 11-10 electrical handy box.
Pressure Sensor
The Pressure Monitor is used to measure differential pressure in the range of +/-1″ wc full scale, +/-8″ wc, 0 ~100 PSI,0~250 PSI.It combines precision, high sensitivity silicon sensing capabilities and the latest ASIC technology to substantially reduce offset errors due to changes in temperature, stability to warm up, long term instability and position sensitivity. BACnet MS/TP and Modbus RTU protocols over RS485,with an ethernet port.
Outdoor Air Temperature Sensor
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.
Pluggable Power Relay
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.
Pluggable Terminal Blocks for OEMs
These plug-in terminal blocks provide easy installation and commissioning for controls and automation projects. There are models available for wire sizes up to 16mm2. There are many different pitches from 2.5mm to 10mm. You can choose the wire insertion direction and plug-in direction to suit most any application.
