Description
Application of control voltage (UE) to the unit initiates the
following sequence:
MRZA:
As the set time delay (tv) begins to run down, the relay remains inactive. At
the end of the continuously adjustable time period, voltage (UR) is applied to
the relay and activates it. Interruption of the input voltage will cause the
relay to release. The module is equipped with two status LED’s. One
indicates the presence of control voltage and the other lights at the end of
the delay period, when the relay is activated.
MRZB:
Application of the control voltage (UE) activates the relay without delay (UR).
At the end of the delay period (tw)the relay releases without regard to the
control voltage. The relay will deactivate and release, if the control voltage
is interrupted during the delay period. Control voltage and relay status are
indicated by LED’s.
MRZE:
Application of the control voltage (UE) will cause the SPDT relay to commence
switching at the set pulse rate. The On-Off time is symmetrical; the rhythm
starts with the “On” time. The status of the pulse generator as well
as the relay is indicated by LED’s.
