REV-201M is designed for the commutation of electrical circuits of 240V 50Hz AC as well as 24V 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 (cyclic) relay 1;
– Operation relay (star-delta);
– 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.
The operation logic algorithm can be selected by the A position DIP switch. The device has 7 selectable time range set by the D1 and D2 DIP switches.
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. Independentoperationofchannels. 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.
The front panel features for each channel a double-color LED with the following algorithm:
