State
Relay contacts are in normal state until the associated setpoint is exceeded, then the relay is
activated and the contact states change.
Select ”Inverted” to reverse the normal operating state of the relay (i.e. Normally open contacts
are in a closed state, and normally closed contacts are in an open state, until the setpoint is
exceeded). ”Inverted” relay operation is functional when power is applied to the M300 trans-
mitter.
Four channel transmitters also allow configuration of a Relay Hold Status of ”Last” or ”Off”.
This is the state the Relay will go to during a Hold status.
