Problem
Here’s a scenario that may be familiar: the current of a high voltage load needs to be monitored with a current sensor, and the current sensor needs an integrated relay with 10A rated contacts. It seems easy, however when working with high voltage, some special equipment (and maybe even a licensed professional) is required. Fair enough, a professional is called to the scene to install the current sensor and relay combination. Everything is going well until it is discovered that the trip point on the current sensor is too high, and something needs to be adjusted! There’s no option but to get the licensed professional back out to the scene to make the small adjustment. This installation is taking a lot of time, and time means money.
Solution
What if Functional Devices had a RIB® current sensor and relay combination product that could eliminate the second trip of the licensed professional? If the above scenario sounds familiar, there may be a benefit to using one of our remote current sensor and relay combination devices (models RIBXLCRA or RIBXLCJA). Read on to see how those products may save you time and money!
When it comes to setting the adjustable threshold on RIB® current sensors, the process may need to be revisited after installation. There are other current sensor and relay combination devices in the market that require access to the high voltage compartment to adjust the current sensor threshold. If RIB® models RIBXLCRA or RIBXLCJA were used, the adjustment screw would be located safely outside of the high voltage compartment, as seen in the illustration below.
Access to the low voltage relay coil input and the current sensor status output is as easy as loosening one screw on the housing cover. The class 2 rating on the low voltage side of the device is maintained because the low voltage portion of the device is located outside of the high voltage compartment. Would you rather have a fixed threshold current sensor? Consider either model RIBXLCRF or RIBXLCJF. As for the choice between a solid core or split core remote current sensor, see the selection chart below.
