MU-WebdynSun – V1.1
9.1.2.
Switching relay outputs
The WebdynSun provides 2 relay outputs. The relays used are electromechanical ones intended for
switching. They are not power relays. They are open when not energised, and their characteristics are:
Current ratings:
• 3 A, 48 V AC.
• 3 A, 30 V DC.
The outputs can be used in their open or closed states, or pulsed, with a pulse duration (closed) of 1 second.
When the gateway is restarted, the bang-bang control outputs switch first to their
default open states, then switch to their last configured states.
Please take all possible safety precautions during this phase.
So as to avoid all risks, we advise using the bang-bang control outputs in pulsed
mode, especially for all power relay purposes.

Dry contact inputs
The WebdynSun gateway provides 4 bang-bang inputs. These 4 inputs have a common earth and are
intended to connect to dry contacts (open/closed). The maximum control impedance is 5 ohm.
To avoid damage to the gateway, do not inject current or tension on the bang-bang
inputs.
