  • 4 operation diagrams
  • 1 switching group contacts 5A/250V
  • Indicator of availability of power
  • Width of the case is 13mm
 
PURPOSE OF THE RELAY
 Time relay RVO-26M is designed to forming delay at off built-in relay after removal of the supply voltage (operation diagram 26 and 27) or for testing fixed time delay after turning on supply voltage.
 
DESIGN OF THE RELAY
 Relay is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, you need to push locks. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are: two turning switches to set the delay time t (setting value units 0-9 and 0-9 tens), green LED power-on «U». On the side surface is located DIP-switch to set a time range (switch 1, 2) and operation diagrams (switch 3, 4).
 
OPERATION OF THE RELAY
Operation diagram and time delay range is selected by DIP-switch, located on the side surface. For each diagram, you can choose one of three (0,1s-9,9s, 1s-99s, 0,1min-9,9min) delay time ranges, advanced to diagrams 1 and 2 has a fourth range 1-99min. The required time delay t is determined by multiplying the numerical value set on the switches "units" and "tens", a multiplier of the selected range on the DIP-switch. The supply voltage is applied to the terminals "+ A1" and "A2". Circuit of connection of relays is shown below and on the case of device.
 
 WARNING:  In the design of the product applied polarized electromagnetic relay with two stable states. Single blows during transport can result in spontaneous switch contacts. Wrong position of the contacts before the first switching on the relay does not indicate defects in the relay. The first time the original (OFF) state of the contacts is restored. Do not install the relay in an area of high vibration, or near devices which cause vibrations when activated (eg, high-power actuators, etc.).

DIAGRAMS OF OPERATING THE RELAY
Диаграмма работы реле времени № 26
 Delay relay operation after power is removed. The relay switches at the same time with applying power. Disabling the relay going after a specified time after the removal of the supply voltage. Time counting is interrupted when the power is turned back and resumed after its removal.
Диаграмма работы реле времени № 27
 Delay relay operation after power is removed. The relay is turned on at the same time power off. relay off after a preset time. When reconnecting the power supply is interrupted the countdown and relay is going off. After the power is turned off the countdown starts again.
Диаграмма работы реле времени № 1
 The counting the set time begins when power is applied, after which the relay switches (switch-on delay). It is turned off, when the power is off.
Диаграмма работы реле времени № 2
 The relay is turned on simultaneously with power supply. Disabling the relay occurs after the set time counting (tripping delay).
