Mechanical Relay Board: 8 gang relay<\/h3>\n
\u00a0 \u00a0 The coils are low power, requiring 20ma at 24VAC (30ma at 12VDC). The SPST relay is rated at 12A\/125VAC, 6A\/250VAC. The relay board comes pre-configured as either 12VDC or 24VAC but you can move some jumpers on the lower side of the PCB which allow you to switch from 12VDC to 24VAC or vice versa in the field.<\/div>\n

Note to the NEST users in the U.S.:<\/strong><\/p>\n

There is usually inventory in the US of A. If the shipping method shows as ‘Fedex’ on checkout then some items in your order are coming from the Shanghai warehouse. Try ordering just the relays alone and shipping will usually show USPS which means the items are in stock in the states.<\/p>\n","protected":false},"excerpt":{"rendered":"
