NOVATEK-ELECTRO LTD Research-and-Manufacture Company MULTIFUNCTIONAL TWO-CHANNEL TIME DELAY RELAY REV-201 USERS MANUAL - 2 - 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). 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. REV-201M contains 2 channels each of them may work in 4 user preset algorithms: - Turn ON time delay relay - Impulse relay - Cyclic relay for the periodic events - Operation 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 When using the REV-201M in Mode 1. The power supply of both channels must necessarily have common neutral. 1.2 TECHNICAL PARAMETERS 1.2.1 Basic technical characteristics are shown below in Table 1.
