Aug 18, 2010 · A rib relay is nothing more than an electrically controlled switch. When voltage is applied ti its coil, a set of contacts closes. Same as any other relay. The main difference here is the rib relay has a 1/2" hub on it that can be installed in a 1/2" KO. Other relays have to be mounted with screws or a DIN rail.

May 4, 2024 · The RIB serving as a motor contactor should not be an issue as long as you stay under the contact rating for inductive loads. But the 2.4 amps at 120VAC for a 1/3hp motor does not sound right. Common motor data charts show 7.2 amps at 120VAC and 3.6 amps at 220VAC for 1/3 horsepower motor.

Dec 27, 2019 · But I'm curious how a relay like the RIB 240 1B satisfies the high/low voltage separation requirement. It looks like it is intended to be mounted on a knockout outside on the breaker panel. However the low voltage coil feed is bundled in with the high voltage tails, as well there is the 24DC incoming from a transformer.

Dec 31, 2024 · I recently updated the RIB relay and transformer. I did a manual reset and the gas flow to the grill continued. However, 3 days later and the owner has been having to manually reset the relay everyday to get the gas to flow. No alarm trigger or error, new RIB relay, new transformer. Could it simply be a bad relay ?

Dec 10, 2024 · You could use momentary switches and a latching relay and only two wires across the warehouse, so the relay coil isn't operating continuously. RIB makes suitable relays for this kind of thing, good quality, made in USA or Canada, you can pick one that will work with a doorbell transformer for control power.

Feb 3, 2021 · This way the relay module is supervised and controllable by the panel. For example, only the smoke detectors in the rooms served by the dampers will cause it to close. The RIB is powered by the 120v for the damper. I don’t put anything on my 24v panel power that isn’t a …

Feb 27, 2024 · I am using RIB relays for my outside landscape lighting. The Caseta switches are only 650 watts and cost $50 / $60 bucks. The RIB can handle a short and are cheaper. I thought the thermostat has to manually open all power legs or you need a disconnect within sight. Or remote lockable.

Feb 4, 2024 · The Better Switch BS200 is a very handy little relay you can easily hide in a standard light switch box. It comes rated for 10 amps, has a built in 12V transformer and can be NO or NC but it can't take the 20 Watt LED load.

Sep 27, 2023 · I have done exactly one of the setups you describe. Commercial environment so I had access to the lighting circuits in all the bathrooms. Installed a RIB in each circuit, used those to initiate a contactor for the fan. Contactor box had a …

Oct 15, 2021 · However, UL has determined that the RIB2401B relay (and any other RIB relay with “B” in the model name after the “RIB” and does not have an override switch) can switch up to 16 Amps worth of an electronic ballast load on the Normally Open relay contact. That rating considers the high in-rush current that electronic ballast loads ...
