The MRB Mechanical Relay Board comes in two models, the 4 gang and the 8 gang versions. The board features status LEDs and a label with writeable surface where you can mark the name of each output.The coils are normally configured as sourcing with a common ground but they can also be factory configured to sinking operation, please write us if you would like the sinking version. The terminals are pluggable with full floating cage type wire clamp which grip the wire firmly, not the lower cost spring terminal style.
Omron General-Purpose Relay available in SPDT and DPDT with either AC or DC coils. It comes with a pluggable base for easy din rail mounting and fast swapping of relays in the field. The narrow width allows for high density i/o in controls cabinets. The LED indicator on the low voltage coil provides handy indication of the relay status.All of the prices below are for the relay with LED option and the din rail base included.
The MR Mechanical Relay is a general purpose relay suitable for both low voltage and power switching. It features a low power coil, the 12VDC version requires only 100ma to energize. The DPDT relay is rated at 10A, 120VAC. Each relay has an LED showing the low voltage status.
This latching, HID lighting control relay is equipped with permanent magnetic latching technology. It is rated for a 25A circuit at 300 and 480 VAC and has an estimated mechanical life of up to 1,000,000 uses. This unit is outstanding value, by special arrangement we are able to offer a brand name product at huge savings under our own white label or your own logo.
Definite purpose contactor is a robust and low cost switching device specifically designed for the heating,ventilating and air conditioning industry. These contactors are the ideal choice for switching fans, pumps, compressors and other typical HVAC loads. They are popular with many large OEM manufacturers and controls contractors. We can brand these under your name or ours, the default item ships as a white box product with no branding.
The Relay Board comes in two versions,one with transformer and one without.It features an area to add your own label. The coils are very low power, requiring less than 30ma at 24VAC. The SPST relay is rated at 12A/125VAC, 6A/250VAC. Each relay has a status LED. The relay board is designed mainly for isolation between thermostat and a fan coil or air handler, 3 relays @ 12A/125VAC, 6A/250VAC, 2 @110V 1A There is a 24V/18VA transformer on RB-XF.
The LRSSR Solid State Relay brings solid state reliability to control systems in HVAC and light industrial duty applications. Long service life and noise free operation even at high switching speeds. Zero turn on circuitry, status LED and compact size make this an excellent choice for switching of compressors, fans pumps. The high speed electrically quiet operation means they’re also suitable for PWM modulating of electric heaters.
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.
The “Plug-in” I/O Module series provide general purpose interfacing for DDC and industrial automation systems. The modules plug into industry standard termination boards and provide optical isolation between the controller and field devices. Color coding identifies modules at a glance.
The SSR Solid State Relay brings solid state reliability and trouble free switching to HVAC installations. CSA approved.A handy LED on the low voltage sideshows at a glance what is going on at the DDC controller.The high voltage side features photo- isolation to 4000V, and a built-in snubber. Each unit is tested under full load condition bef ore delivery.
