- 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-201М). 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. - Page 3 - 3 - Electrical characteristics for the Output terminals Cos Maximal current at Maximal Maximal Voltage Maximal Current at U~250В capacity =28V 7 А 1250 ВА 250 В 3 А Arbitrary mounting position Standard 35 mm DIN rail mounting 1.2.2 Front panel view and outer dimensions are shown on figure 1.
- Page 4 - 4 - approximately 250 milliseconds. This happens due to smooth voltage increase on the power supply source of REV-201M. Kindly see Figure 2 below for more details. 1 – Voltage growth curve on the REV-201M input power supply 2 – Curve showing the triggering time for the output terminals when the REV-201M has minimal (zero) time delay settings.
- Page 5 - 5 - When the Turn ON time interval comes to an end REV-201M turns OFF the load and REV-201M switches to the idle mode. LED color indicator changes to GREEN. 1.2.3.3 Cyclic operation mode Position of DIP switches A “...

- 6 - fixed. On special customer request for the algorithm “START-PAUSE-START” it’s possible to change the timing intervals and delays as per requirement REV-201M has internally preprogrammed block that doesn’t allow to turn ON the power load on Channel 2 until output contacts of Channel 1 are being closed (ON). 2 GENERAL USE AND APPLICATION 2.1 FIRST START UP PREPARATIONS 2.1.1 Safety precautions... - Page 7 - 7 - Adjustment of time intervals should be made with the use of potentiometer knobs 2, 3 (Figure 1) for the Channel 1 and potentiometer knobs 7, 8 (Figure 1) for the Channel 2. Timing limits for the knobs are set up below with the use of DIP switches 4 (Channel 1), 9 (Channel 2) (see Figure 1) in accordance with the Table 3: Table 3...
- Page 8 - 8 - 3.2 It is recommended to perform technical maintenance every 6 months of use. Look at the case of REV-201M and make sure that there are no dents or any other mechanical damages. Make sure that all the wires are tightened well and properly connected and pay attention to the absence of burned contacts.
