Connecting outputs

Connecting Relay Outputs

The key feature of the Covermix version is that it has 32 relays in total, but half of them (16) are are paired to control up to 8 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. The rest of relays (16) are classic 10A relays which are usually used in lighting circuits. This provides tremendous possibilities for controlling a large number of independent circuits from a single device, saving both space and complexity.

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 (e.g. cover motors, lighting), 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) for covers - wire is as follows: RCD Protection -> Overcurrent Protection (MCB) -> COM terminal in boneIO -> UP/DOWN terminal in boneIO -> COVER

The correct current flow for the phase (L) for relays - wire is as follows: RCD Protection -> Overcurrent Protection (MCB) -> COM terminal in boneIO -> OUT terminal in boneIO -> Load

Part 1: Connecting Cover Outputs (OUT1 - OUT16) Cover 1-8

These outputs are designed to control bidirectional 230V AC motors for roller shutters or blinds. They are grouped in pairs (e.g., OUT1/OUT2, OUT3/OUT4) and feature a hardware interlock to prevent the motor from being damaged.

1. Connect the phase wire (L), coming from the dedicated overcurrent protection (MCB ≤ 10A), to the COM terminal of the selected Cover output (e.g., Cover 01 COM).
2. Connect the wire leading to the Cover motor UP to the UP terminal of the same output (e.g., Cover 01 UP).
3. Connect the wire leading to the Cover motor DOWN to the DOWN terminal of the same output (e.g., Cover 01 DOWN).
4. Run the neutral wire (N) directly to the load (cover engine).

Part 2: Connecting Relay Outputs (OUT17 - OUT32)

These are standard relay outputs for general-purpose use, such as controlling lighting.

1. Connect the phase wire (L), coming from the dedicated overcurrent protection (MCB ≤ 10A), to the COM terminal of the selected output (e.g., COM9 for OUT17 and OUT18).
2. Connect the wire leading to the load (e.g., a lamp) to the corresponding output terminal (e.g., OUT17).
3. Run the neutral wire (N) directly to the load.

Safe Connecting of COM and OUT Terminals

In the boneIO controller, version Covermix every two outputs (e.g., Cover 01 UP, DOWN) and also outputs dedicated for lights (e. g. OUT17, OUT18) 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.

1. REMEMBER, ensure that the relevant circuit breakers in the electrical cabinet are turned off.
2. Connect the phase wire (L), coming from the overcurrent protection, to the appropriate COM terminal - tighten it with adequate force.
3. Connect the wire leading to your load (e.g., cover motor, a light bulb) to its corresponding output terminal - tighten it with adequate force.
4. Run the neutral (N) wire directly from the neutral bar to the load.
