7.1.2. Digital inputs section
Digital inputs can be used for monitoring the state of discrete devices – motion sensor, door
contact, relay contact, alarm output etc.
Digital inputs are sampled every 10mS. The change of input status is considered valid if the same
value is read in 3 consecutive samples (30mS).
Status of every input is shown by text and by color.
The default descriptions and status names can be changed in “Setup-Input/Output”.
7.1.3. Analog inputs section
Analog inputs can be used for monitoring of DC voltage sources – analog sensors, batteries,
power supplies, solar panels etc.
Analog inputs 3 and 4 can be also used for monitoring of 0-20mA current loop
sensors/transmitters. The mode can be changed in “Setup-> Input/Output” section.
Analog inputs are sampled faster, but the new actual value is changed in 0.5 seconds. All 250
readings between the value changes are averaged.
For every analog input “Unit”, “Multiplier” and “Offset” can be set in “Setup-> Input/Output”
section.
7.1.4. Relay section
The section displays the current state of relays. Each relay can be activated either remotely or
locally from the status of a monitored parameter. For locally activated relays a text description of
the controlling parameter is displayed rather than buttons.
Pulse duration and parameters for local relay activation can be set separately for each relay in
“Setup->Input/Output->Relay outputs”.
