Functional Devices RIB[*]24B-BCAI BACnet relay with analog input BACnet points list
Updated 12 November 2026
A small BACnet MS/TP relay module: one relay output (BO1), two binary inputs and one analog input that can be set for 0-5 V, 0-10 V or a 10K thermistor. Three BVs and two AVs run an optional on-board set point function on the analog input.
This page lists 9 BACnet objects for the Functional Devices RIB[*]24B-BCAI BACnet relay with analog input — 5 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Functional Devices’s own free documentation, linked below.

BMS integration notes: Functional Devices RIB[*]24B-BCAI BACnet relay with analog input
Command the relay through BO1 and read the inputs. Leave BV1 off unless you want the module to switch BO1 itself from AI1 against AV1/AV2.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.
| Object | Name | Why | Access |
|---|---|---|---|
| BO 1 | BO1 | Relay command | Command |
| BI 1 | BI1 | Binary input 1 status | Read |
| BI 2 | BI2 | Binary input 2 status | Read |
| AI 1 | AI1 | Analog input value | Read |
Network setup
- The PICS prints the device object ID default as DE277000 (vendor ID 277); it is writable.
- MS/TP master; baud rates are listed in the PICS. Max_Master defaults to 127.
Watch out for
- BV3 reports whether the set point settings are valid before the set point function will act.

No points match these filters.
Object ID lookup: Functional Devices RIB[*]24B-BCAI BACnet relay with analog input point IDs by name
Integration notes
- Object names are user-writable and the PICS prints no factory default name, so each object is listed by its printed ID (BI1, BO1...).
- BO1 has a 16-level priority array, minimum on/off times and a writable relinquish default.
- AI1 units are writable (any BACnet unit) and the input type is set through Device_Type.
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the RIB[*]24B-BCAI BACnet relay with analog input and exports what it actually has to Excel — free.

Questions about the Functional Devices RIB[*]24B-BCAI BACnet relay with analog input
How many BACnet points does the Functional Devices RIB[*]24B-BCAI BACnet relay with analog input have?
This list has 9 BACnet objects: 1 analog input, 2 analog values, 2 binary inputs, 1 binary output, 3 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Functional Devices RIB[*]24B-BCAI BACnet relay with analog input BACnet points are writable?
5 of the 9 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.
Where is the official Functional Devices RIB[*]24B-BCAI BACnet relay with analog input BACnet documentation?
The source is BACnet RIB Protocol Implementation Conformance Statement, RIB[*]24B-BCAI PICS v1.50, revision 2018-03-26, published free by Functional Devices at https://www.functionaldevices.com/sfsites/c/cms/delivery/media/MCYTFJGV2JYFC2NP7NTRLT2YH6G4.
What are the minimum BACnet points to integrate the Functional Devices RIB[*]24B-BCAI BACnet relay with analog input?
Start with BO 1 BO1 (Relay command); BI 1 BI1 (Binary input 1 status); BI 2 BI2 (Binary input 2 status); AI 1 AI1 (Analog input value).
How do I check these points on the real RIB[*]24B-BCAI BACnet relay with analog input?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
