12 DO
A powerful relay output module. Industrial-grade protection with multiple temperature sensors next to the relays to make sure there is no overheating. The module's software makes sure the total switched load does not exceed the main circuit breaker performance. Multiple phases can be connected. Fixed screw terminals do not release the cables. All outputs are universal for standalone switched output, AC blinds motor controller or PWM. No outputs stay unused.

New Revision 3.0
We’ve improved the two most common causes of complaints:
- The new TBU-RS085-300-WH protection chip provides robust protection for the bus against overvoltage and short circuits.
- Replaced the DC/DC converter with a more robust model.
Features
- 12x potential-free relay outputs, 16A
- Relay lifetime: 100 000 cycles under maximum load, 2 000 000 cycles under average load
- Maximum total load 50A
- Output configurations:
- Standalone switched output
- AC blinds motor with internal blocking of both outputs
- PWM output
- Standby energy consumption: 1W
- Energy consumption for one relay closed: 0.4W
- Power dissipation for each 1A of load: 0.16W
- Maximum power dissipation at full load of 70A for all relays closed: 1+0.4x12+0.16x70=17W
- Power supply 24VDC +-10%
- Protection: IP20, operating temperature: -20°C to 40°C
- DIN rail, 6 modules. Width 107 mm, height 59 mm
Wiring information
Each relay is potential-free. Wire outputs as follows:
-
Bring the phase (Lx) from the distribution board to the first screw terminal of the first output.
-
Cut short wires (“bridges”) and connect them from that same terminal to the common screw of the next output, and continue this for all outputs that share the same phase.
-
Connect each second screw of the relay output to its respective load (light, socket, motor, etc.).
-
Connect the neutral (N) of each load directly to the neutral busbar, not through the module.
-
Multiple phases may be used on different groups of outputs if required.
-
The module supports standalone switching, AC blinds (with interlock), and PWM mode.
