Connecting Relay Outputs (Cover Motors)
The key feature of the Cover version is that it has 32 relays, which are paired to control up to 16 roller shutter motors. Each pair of relays (e.g., Cover 01UP/DOWN, Cover 02 UP/DOWN) is protected by a hardware interlock to prevent simultaneous 'up' and 'down' signals, which protects the motor from damage.
Protection and Correct Wiring Order
It is critical that all overcurrent protection (Miniature Circuit Breakers, MCBs) and residual-current devices (RCDs) are installed in the circuit before the boneIO controller.
The current rating (in Amps) of the overcurrent protection must be sized appropriately for the planned load of the circuit (in this case - cover motors), but at the same time, it must not exceed the maximum rated current of the relay, which is 10A.
The correct current flow for the phase (L) wire is as follows:
RCD Protection -> Overcurrent Protection (MCB) -> COM terminal in boneIO -> UP/DOWN terminal in boneIO -> COVER
Example 1: Controlling a standard cover circuit
- Connect the phase wire (L), coming from the dedicated overcurrent protection (MCB ≤ 10A), to the
COMterminal of the selected Cover output (e.g.,Cover 01 COM). - Connect the wire leading to the Cover motor UP to the
UPterminal of the same output (e.g.,Cover 01 UP). - Connect the wire leading to the Cover motor DOWN to the
DOWNterminal of the same output (e.g.,Cover 01 DOWN). - Run the neutral wire (N) directly to the load (cover engine).

Safe Connecting of COM and OUT Terminals
In the boneIO controller, version Cover every two outputs (e.g., Cover 01 UP and DOWN) share a single common power terminal COM. This means that the phase wire (L) from a single circuit breaker supplies a pair of relays - with hardware interlock.
- REMEMBER, ensure that the relevant circuit breakers in the electrical cabinet are turned off.
- Connect the phase wire (L), coming from the overcurrent protection, to the appropriate COM terminal - tighten it with adequate force.
- Connect the wire leading to your load (e.g., a cover motor) to its corresponding output terminal - tighten it with adequate force.
- Run the neutral (N) wire directly from the neutral bar to the load.
