  • Time delay after switching off the supply voltage: 0,1 - 9,9s, 1 - 99s and 0,1 - 9,9min
  • Setting time delay by using two decimal switches in steps of 1% of the maximum range
  • Three operation diagrams (26, 27 and 31) or a function of momentary contact (MC)
  • 2 switching group contacts 8A/250V
  • Indicator of availability of power
  • Width of the case is 18mm
 
PURPOSE OF THE RELAY
 Time relay RVO-26 is designed to generate a delay of switching off the executive relay after removal of the power supply (operation diagram 26 and 31) or to turn on the executive relay after removal of the power supply (operation diagram 27) at a preset time delay. The relay provides a work of built-in contact group without time delay (diagram of the MC).
 
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», rotary switch "multiplier" to choose the diagram and set the time range.
 Does not contain precious metals.
 
OPERATION OF THE RELAY
 Operation diagram and time delay range is selected by a switch "Multiplier". For each diagram, you can choose one of three (0,1s-9,9s, 1s-99s, 0,1min-9,9min) delay time ranges. The required time delay t is determined by multiplying the numerical value set on the switches "units" and "tens", on a multiplier of the selected range on the switch "Multiplier". In a position "MC" the relay works in mode momentary contact.
 Operation diagram 26 - when a power is turned an indicator «U» is lighted and the executive relay runs, and the contacts 15-18 and 25-28 closes. When removing the power supply is switched off an indicator «U» and starts the counting of set time, after that the executive relay is switched off (contacts 15-16 and 25-26 closes). If during the reference time a voltage will be supplied to the relay, the counting stops, after removing the power supply, a counting begins again.
 Operation diagram 27 - when power is turned an indicator «U» is lighted. When removing the power supply an indicator "U" is switched off and the executive relay is turned at the duration of the preset delay time t, and the contacts 15-18 and 25-28 closes. After counting time delay, the executive relay is switched off and contacts 15-16 and 25-26 closes. If during the reference time will be re-energized to the device, then the executive relay switch off, the contacts 15-16 and 25-26 will be closed and the counting will be interrupted. When removing the supply voltage the executive relay will switch on, the contacts 15-18 and 25-28 will close and will begin counting the set delay time t.
 Operation diagram 31 - when power is turned an indicator «U» is and starts counting the set delay time. After the counting of time delay, the executive relay is on and the contacts 15-18 and 25-28 closes. When removing the power supply is switched off «U» indicator and begins a counting of the time delay. After the counting of time delay, the executive relay is switched off and contacts 15-16 and 25-26 closes. If during the counting of the delay time will be re-energized to the device, then the executive relay will remain off and the counting will interrupted.
 Operation diagram of the MC - when power is turned an indicator «U» indicator turns on, the executive relay is on, contacts 15-18 and 25-28 closes. When removing the power supply an indicator "U" is switched off, the executive relay is switched off and contacts 15-16 and 25-26 closes. The supply voltage is applied to the terminals "+ A1" and "A2".
