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.
