REV-201М
This present manual contains necessary information about application, main operation principles and
adjustment setting for the two-channel electronic time delay relay REV-201M (hereinafter REV-201
М).
1 GENERAL DESCRIPTION AND OPERATION
1.1 APPLICATION
REV-201M is designed for the commutation of electrical circuits of 240V 50Hz AC as well as 24
– 100V DC
electrical circuits with the adjustable time delay setting.
The relay has two channels and can be operated by one of seven operation algorithms that the user specifies:
-
Turn
ON
time delay relay;
-
Pulse relay 1;
-
Intermittent relay 1;
-
Operation relay *.
-
Pulse relay 2;
-
Intermittent relay 2;
-
Off-delay relay.
* REV-201M could be used as the relay of pre-starting signalization for the machinery that require to announce
that some mechanism or machinery will soon take a start to make people aware of this and get away from the risky
zones. Widely used for steel plants, heavy machinery, cranes and construction mechanisms as well as mining
companies for the technological stuff safety.
Time delay setting for each channel starts from the moment of the power supply given to the corresponding
channel. REV-201M allows to provide 2 modes of operation:
Mode 1. Independent operation of channels.
To each of two channels power supply is given independently
and thus each channel starts the countdown from the moment the power supply is given. This is the mode when 2
independent time relays are functioning in one compact case housing (2 time delay relays in one case).
Mode 2. Parallel operation of the channels.
To each of two channels the power supply is applied
simultaneously. Thus the time countdown on each channel starts at the same time and comes one and the same input
power supply. Triggering time corresponds to the user-adjusted settings for each of the channels. So the REV-201M in
this mode operates like one time delay relay with 2 output contacts that have the same or different time settings.
ATTENTION!!! The power supply of both channels must necessarily have common neutral.
