We all know our favorite RIB Building Automation products that we use on every job, but here’s a list of Functional Devices that you should keep in your back pocket.
RIBMN24Q2C, Q3C, Q4C
Running out of Binary Outputs on your controller? Try the RIBMN24Q2C. This device line is similar to a sequencing relay that accepts an analog signal and creates Binary Outputs. Feed it a single 0-5/10 vdc signal and get multiple Binary Output relays. What makes this device unique from a sequencing relay is the outputs do not have to be in sequence. Depending on the voltage input, the Binary Outputs are activated in varying states. See the graph below.
This series of RIB Building Automation models is available with 2, 3, and 4 Binary outputs, giving you the ability to command several motors, fans, pumps, etc. with a single Analog Output from your controller. The relay NO/NC outputs are rated for general use, so no additional relays are needed for this model.
This 2-in-1 device will save you time and money. The RIBHX24BA is a combination relay and current switch. Command and Status in a box, if you will. Great for enabling an exhaust fan and picking up verification with one device, which can be hub mounted at the nearest junction box.
Complicated air handlers have many safety devices. When a unit is disabled by a High Static Pressure sensor, wouldn’t it be nice if you were able to track that with your controller? The RIBMNWLB-7-BC is the newest addition to a line of fan safety cut-out devices we currently offer. This particular device has 6 hardwired safety device inputs, that will open a set of contacts in the event a safety device is tripped. Each point is viewable via a BACnet connection, as well as a seventh input for fan status. Save valuable input space on your controllers with the RIBMNWLB-7-BC.
The RIB01BDC is a “dry contact” relay. This makes is great for applications that require a lengthy wire pull, where voltage drop may come into effect. Instead of running a 24 volts output over a long run, this relay uses a dry contact, meaning that you only have to connect two wires together to enable the relay. 120 vac power is required at the relay, but it can be commanded from a controller from a very long distance! Not to mention, the dry contact is considered Class 2 wiring, so depending on the specification, may not require conduit.
This BACnet relay accepts an Analog Input. Instead of placing a DDC controller next to a unit heater in a mechanical room, the RIBMNW24B-BCAI could be installed at the Unit Heater. Add a temperature sensor to this relay, and it will enable the UH if the temperature drops below a determined setpoint. Since this relay can communicate over BACnet, no controller is required! The relay can be track mounted, or can be ordered with a NEMA 1 or 4 housing.
We all know and love the versatility of the RIBU1C, but did you know we have a model that can be mounted outdoors? The RIBU1C-N4 replaces the traditional grey relay housing with a clear, NEMA4 rated housing that is resistant to the elements! Look online at FunctionalDevices.com for a full list of NEMA4 rated RIB relays to fit your specific application.
We covered what part can get you out of a pickle when you run out of Binary Outputs, but what if you’re monitoring an excessive amount of Binary INPUTS? Enter the RIBMNWD12-BCDI. Another product from our Intelligent Field Device line, this BACnet enabled logic board accepts 12 Binary Inputs, saving you from placing another costly DDC Controller in your panel. Alternatively, this device could be placed in a piece of equipment, and BACnet cabling could be pulled back to your main panel instead of 12 separate cables when monitoring a piece of equipment that does not have its own BACnet connection.
These products may be too big to keep in your back pocket, but keeping them in your service van or truck could really get you out of a pickle.
