Some common questions concerning I/O modules for the JACE 8000.
Q: How does the IO R module communicate with the JACE 8000?
A: The JACE 8000 communicates to the IO R using an updated NRIO driver over a dedicated RS-485 network. Tridium recommends placing the JACE 8000
485 biasing switch in the “end” position when communicating with the IO R.
Note: As the JACE 8000 485 ports are isolated, all three conductors must be used to ensure consistent communication.
Q: How many IO R modules can I connect to a JACE 8000?
A: The JACE 8000 is licensed to communicate with sixteen (16) addressable modules. The IO-R-16 counts as one (1) module, and the IO-R-34 counts as two (2) modules. The JACE 8000 can communicate with up to sixteen (16) total IO-R-16 modules or eight
(8) IO-R-34 modules. The various combinations of IOR-16s and IO-R-34s are contained in the installation guide.
Q: How is the IO-R-34 powered?
A: The IO-R-34 input power requires 24V AC or DC. Please consult the installation guide for more information on transformers and sizing.
Q: How is the IO-R-16 powered?
A: Tridium recommends the IO-R-34 as a power source for the IO-R-16. The IO-R-34 is capable of powering up to four (4) IO-R-16 modules simultaneously. Alternatively, a 15VDC source can be used instead. Please consult the installation guide for more information.
Q: Can I use the JACE 8000 and IO R to replace my existing JACE 2, 3, 6 and 6E with NDIO?
A: Yes, Tridium designed the IO R and JACE 8000 to replace existing legacy JACE controllers. Physical installation:
Footprint—The JACE 8000 and IO R products occupy the same approximate space
Wire compatibility—The pin out between IO-R-16 and T-IO-16 is identical. The pin out between IO-R-34 and T-IO-34 is identical.
Connector compatibility (Plug and Play compatibility)—The connectors between IO-R-16 and T-IO-16 are identical. The connectors between IO-R-34 and T-IO-34 are identical.
Station compatibility—Tridium has developed a network conversion tool for migrating an NDIO to NRIO network. Please consult the updated “NRIO driver guide” for more details.
Q: Can I use the JACE 8000 and IO R to replace my existing JACE 2, 3, 6 and 6E with NRIO?
A: Yes, Tridium designed the IO R and JACE 8000 to replace existing legacy JACE controllers.
Footprint—The JACE 8000 and IO-R-16 products occupy the same approximate space as the T-IO-16-485.
Wire compatibility—The pin out between IO-R-16 and T-IO-16 is identical
Connector compatibility (Plug and Play compatibility)—The connectors between IO-R-16 and T-IO-16 are not the same and will require using the ones provided with the IO-R-16.
Station compatibility—The IO R modules utilize the same NRIO network as before.
Existing stations can be updated easily to use the new modules if desired.
Q: Can I migrate a Niagara AX or Niagara 4 station with NDIO-to-NRIO?
A: Tridium has developed a network conversion tool for migrating an NDIO-to-NRIO network. Please consult the updated “NDIO-to-NRIO Conversion Guide” for more details.
Q: Are the Relays for the digital outputs Normally Open (NO) or Normally Closed (NC)?
A: The digital outputs are Form A relays, which are Normally Open.
Q: What are the dimensions of the IO R?
A: IO-R-16: 82.5mm (w) x 116mm (h) x 61mm (d)
IO-R-34: 162mm (w) x 116mm (h) x 61mm (d)
Q: Will the IO R function without a JACE 8000?
A: The IO R product requires continuous communication with the JACE 8000 to function.
However, Tridium has enhanced the performance of these modules to include programmable output states during power-up, and communication lost scenarios.
Please see “NRIO Driver Guide” for more information on configuring default output states.
Q: What agency certifications does the IO R meet?
A: Please see the IO R data sheet for the most up-to-date information.

- C-UL
- CE EN 61326-1:2013
- RCM
- FCC part 15, class b

- China RoHS
- Open Energy Management Class 2
Q: Does the IO R plug directly into a JACE 8000?
A: The IO R does not plug directly into the JACE 8000 side connector. The IO R can be mounted next to or remotely from the JACE 8000, but communicates over an RS485 network.
Q: What is the side connector on the IO R used for?
A: It contains five (5) signals. Three (3) pins for RS485 (+,-,S), two (2) pins for power (+,-).
The connector is utilized for:
Connecting the network from the IO R
back to the JACE 8000
Run RS485 and power signals to
adjacent DIN rails
Q: Are the IO-R-16 or IO-R-34 capable of controlling floating actuators?
A: Tridium does not recommend using the IO R products with floating actuators.
Q: Can we use only IO-R-16s with the JACE 8000?
A: The JACE 8000 is capable of working with IO-R-16 modules exclusively. However, you will need to provide your own 15VDC source. Please see the installation guide for more details on using an IO-R-16 with separate 15VDC power supply.
Q: What environmental conditions can the IO R operate in?
A: Operating temperature: -20–60°C; Storage temperature: -40–85°C; Humidity: 5%–95% — Non condensing; Shipping & vibration: ASTM D4169, Assurance Level II
