SmartCore wiring overview and connection diagram

CountTypeRating
Outputs12 relaysPotential-free (dry contact)16 A; voltages and phases are freely mixable across relays
Inputs12 digitalOpto-isolated, 2 groups of 6 (COM per group)12 V DC – 230 V AC, use one voltage type per group (all DC or all AC)

Inputs, outputs and the device's power supply are electrically isolated, so they don't need to share a breaker, neutral, or phase.

1. Power

Choose one power supply only: PoE or 12–24 V DC.

Power over Ethernet (PoE)

Connect an Ethernet cable from a switch port to the LAN terminal.

External 12–24 V DC

  1. Mount a 12–24 V DC DIN-rail PSU and wire L and N to the PSU input.
  2. Wire PSU +V to DC PWR (+), GND to DC PWR (−).

2. Outputs

230 V AC loads

  1. Wire the supply phase (L) to the relay input.
  2. Wire the load to the relay output.
  3. Return the load through neutral (N); bond metal loads to PE.

24 V DC loads

  1. Wire V+ to the relay input.
  2. Wire the load to the relay output and return it to GND.

Window coverings (2 relays per motor)

  1. Pick two adjacent relays, one for up and one for down.
  2. Wire the supply phase to both relay inputs.
  3. Wire the motor's "up" lead to one relay output, the "down" lead to the other.
  4. Return the motor through neutral.

Any bi-directional load (door operator, valve actuator) follows the same pattern.

3. Inputs

SmartCore inputs and 24 V power supply wiring configuration

Each group (1–6 and 7–12) has its own COM reference. Within a group, use one voltage type.

DC inputs (12–24 V DC)

  1. Connect the group's COM to the DC supply.
  2. Wire the switch or contact between the DC line and an input terminal.

AC inputs (230 V AC)

  1. Connect the group's COM to N.
  2. Wire the supply phase through the switch or contact to the input terminal.

L1, L2 and L3 can be mixed across inputs in the same group.

Powering SmartCore over PoE

  1. Leave the DC PWR terminals unconnected. Do not feed DC and PoE at the same time.
  2. Connect the LAN port to a PoE switch or a PoE injector.

If you still want low-voltage DC inputs while running on PoE, you need a separate DC source for the input COM.

4. DALI

The DALI bus (DALI+ / DALI−) carries lighting commands and sensor events. The SmartCore is the DALI-2 master and addresses up to 64 devices (0–63) and another 64 DALI ensors.

WARNING

Bus power: Either use the integrated 130 mA supply or an external DALI PSU, never both.

DALI lighting

SmartCore DALI bus wired to DALI lamps of different types

Wire DALI+ from SmartCore to DALI+ on each fixture and DALI− from SmartCore to DALI− on each fixture.

DALI sensors and input devices

DALI sensors like keypads, motion sensors, temperature controls etc. are wired onto the same DALI bus as DALI lighting.
