Introduction
If desired, you can connect the SM70 to an external, mains-powered device, such as an alarm, siren, extractor fan or ozone generator. To do this, you need to include a separate mains rated relay.
The set point of the on-board relay activates the relay switch, which controls your external device.
The SM70 enclosure is pre-drilled and fitted with a cable gland to facilitate a cable connection to the relay, data output connectors and analogue output.
The onboard relay output is 24V; 5A (max).
Note: Mains equipment should only be wired by a certified electrician.
