Example
Line 1 has been configured with a source data node as a Sentinel-Analog with the loop current (in μA)
as the selected register. The relay will energize when the loop current is above 1400μA (14mA) and
de-energize when the loop current is below 1300μA (13mA). Note that this configuration has a
1000μA (1mA) hysteresis factor.
In this example all 4 source nodes are assigned to the same destination Slave ID and relay channel so
the following statement applies:
If more than one rule is assigned to the same destination RSD Stick (or gateway
output) and relay channel, then all of the rules must meet the energize condition for
the remote relay to be energized.
Alternatively, this means that if any one of the four source node’s logic results in the
“de-energize” condition being true the relay will be de-energized (safe).
