Connecting Relay Outputs (10A)

The key feature of the 32x10A model is its high output density, integrating 32 relays of 10A each into a remarkably compact form factor. 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., the wattage of the lights), 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 -> OUT terminal in boneIO -> Load

Example 1: Controlling a standard circuit

1. Connect the phase wire (L), coming from the dedicated overcurrent protection (MCB ≤ 10A), to the COM terminal of the selected output (e.g., COM 1 or COM 2).
2. Connect the wire leading to the load (e.g., an outlet) to the NO (Normally Open) terminal of the same output (e.g., OUT 1).
3. Run the neutral wire (N) directly to the load.

Safe Connecting of COM and OUT Terminals

In the boneIO controller, version 32x10A every two outputs (e.g., OUT1 and OUT2) share a single common power terminal COM. This means that the phase wire (L) from a single circuit breaker supplies a pair of relays.

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., 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.
