• Description of Airotronics Relays

  Our first industry breakthrough was packing all the functionality of a plug-in into a compact 2" x 2" cube. These relay output cube timers were capable of handling loads up to 20 amps or 1.5 HP without heat sinking. Further developments include handling loads up to 30 amps or more. Continuing innovations to our "cube" product lines serve the needs of manufacturers worldwide, doing all that can be done by a plug-in timer, but with a smaller footprint and at lower cost. Currently, we lead the way in design and production of specialized microprocessor-based controllers. For applications requiring complex control of multiple inputs and outputs, our MC series are made-to-order.

• Flashers

  CUBE SOLID STATE, FLASHER, 1 AMP THKA Timers / Flashers THKA timers are solid state output units with digital timing and similar on/off cycle times. The THKA comes in a 2" square case. Ease of installation and hook-up is a primary design benefit. All models with integral time adjustment knob or factory-fixed time require only two connections. They may be wired in-line just like a single pole switch. Units with external time adjustment have two additional terminals for the resistor or potentiometer.

• Motion Detectors

  TGMPL series Cube Relay Single Shot timers are a unique combination of digital CMOS timing circuitry with a relay output in a compact 2” x 2” configuration. These units provide the same functional performance as plug-in relay timers, but at significant cost savings.

• Current Sensor

  The HCS is a high-range current sensor with sense capabilities from 8 to 60 amps AC. The set point is either factory fixed or adjustable. HCS is completely self-powered with solid state DC switching to interface with a Programmable Logic Control (PLC) or control relays.

• Microprocessor

  The MC Series is a range of microprocessor-based modules which can be used for sophisticated control applications. They are designed to handle complex functions,making them an economic substitute for Programmable Logic Controls (PLC). They are pre-programmed at the factory for the customer’s particular application and can have up to six inputs and multiple outputs up to 60 amps. In addition to PLC applications, the MC may be used for cam timers, coin counters/accumulators, door/gate controls or where multiple timers are required.

• Solid State

  The TH3AC are Anti-Short-Cycle timers with solid state output for compressor protection. An optional “Delay On Make” function is offered for sequencing or prevention of contactor chatter. Simple 3 terminal connection and encapsulated 2" x 2" package. Anti-short-cycle timers prevent premature cycling of compressors in refrigeration, air conditioning and heat pumps, there by reducing nuisance tripping of fuse or circuit breaker.

• Timers

  CUBE RELAY TIMER, 10 AMPS The TGSCB series meets the needs of HVAC applications requiring more than 1 amp output for compressor protection. An optional 1-second Delay On Make is offered to prevent contactor “hum.” Simple 3 terminal connection and an encapsulated 2" x 2" package. Anti-short-cycle timers prevent premature cycling of compressors in refrigeration, air conditioning and heat pumps, thereby reducing nuisance tripping of fuse or circuit breaker.
