Implementation

3min

The SCALAE RELAY is designed for rapid implementation of new and existing systems.

Installation Options

The module offers 2 recommended installation options.

  • Direct Mounting: For a more cost-effective mounting method, the module includes 4 mounting points. Four holes can be drilled, and aligned with the PCB Stand-offs are then used to mount it elevated from the mounting surface.
  • DIN Rail: A sized DIN Rail mounting platform is available. The unit is inserted into the DIN Rail enclosure and then the assembled module is then added to a panel.

Connections

Inputs

tivating an input is easily accomplished by closing or shorting the two pins. This The PCB is powered independently by a DC power supply, at around ~5vdc, 500 mA. Owing to this, accompletes the circuit to ground and the Opto-couplers out is powered. This then drives the transistor and energizes the relay coil.

Outputs

The relay used is a single pole, double throw. This enables each relay to be wired up either as normally open or normally closed. The module is labeled and a circuit diagram is provided to illustrate this connection.
