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.
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.
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 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.
