INTERMEDIATE RELAY
Introduction
An intermediate relay is an electromagnetic switch that acts as a buffer between a low-power control circuit and a high-power load circuit. It is used to amplify signals, isolate circuits, and split control signals into multiple outputs.
Main Functions:
- Signal amplification: Allows small current/voltage signals (e.g., from PLCs or sensors) to directly control heavy load devices like motors or lighting systems.
- Electrical isolation: Ensures safety by protecting the central controller from overcurrent and overvoltage issues in the load circuit.
- Contact multiplication: From a single input signal, the relay can activate multiple contacts (usually 4 to 8) to control several components simultaneously.
Structure & Classification:
- Structure: Consists of an electromagnetic coil, a contact system (Normally Closed NC / Normally Open NO), a spring, and a protective housing.
- Classification: Categorized by specifications such as voltage (5V, 12V, 24V DC, 220V AC...) or the number of pins (5 pins, 8 pins, 11 pins, 14 pins).

- Max.On Time: Sets the stage of “on” and display the maximum “on” time.
- Max.Off Time: Sets the stage of “off” and display the maximum “off” time.
- ton: Divides the “on” time by 10 and multiples by displayed value.
- toff: Divides the “off” time by 10 and multiples by displayed value.
* Example: Working time(on) is 75minutes, waiting time (off) is 60seconds. - Turn on the stage button to 100m and ton button between 7-8. “On” time will be adjusted to 75 minutes.
- Turn off the stage button to 100s and toff button to 6. “Off” time will be adjusted to 60 seconds.
* Note: In order to adjust much sensitive higher time values, set “t” by chronometer in low stages and increase the stage to the time required.
* Example: Working time (on) 7,5 hours and waiting time (off) is 50 minutes. - Turn on the “on” stage button to 10s. and “ton” button between 7-8. Power on the device and check for 7.5 seconds with chronometer. If it is high or low, re-set “ton”.
- Power on and check again. Later, turn on the “on” stage button to 10h, in this case “on” time will be much sensitive.
- Turn on the “off” stage button to 10s. and “toff” button to 5. Power off the device and check for 5 seconds with chronometer.
If it is high or low, re-set “toff”. Power on and check again. Later, turn off the “off stage button to 100m, in this case “on” time will be much sensitive.
After time settings, power on the device. at the beginning, “on” time will count and “on” led will flash. While counting, relay contact out is (NO) 3 pole.
When the counting finishes, “off” time will start to count and off led flashes. While counting “off” time, relay contact out is (NC) 1 pole.
Till the power is off, device keeps counting on and off times in turn.

OVER/UNDER VOLTAGE & SEQUENCE RELAY
Model VPR-A2-380/3L
Introduction
Voltage control relays are designed to protect devices with sensitive operating voltage values from faults that may be caused by mains voltage.
Protection Functions
- Under Voltage Protection - To enter the error state: If one or more of the phases goes below the low voltage set value, the UV LED is on, the device waits until the set delay time (DT), after the time has elapsed the relay gets de-activated and the relay LED is off.
- Under Voltage Protection - Exiting the error state: When all phases goes above by 3% of the low voltage set value, the device waits for the reset time (RT). After the time passes, the UV LED is off, the relay gets activated and the relay LED is on.
- Over Voltage Protection - To enter the error state: If one or more of the phases goes above the high voltage set value, the OV LED is on, the device waits until the set delay time (DT), after the time has elapsed the relay gets deactivated and the relay OUT is off.
- Over Voltage Protection - Exiting the error state: When all phases drops below by 3% of the high voltage set value, the device waits for the reset time (RT). After the time passes, the OV LED is off, the relay gets deactivated and the relay LED is on.
- Phase Sequence Protection: If the phase sequence of the device is reversed, the phase sequence error PS LED will light up and the relay will not gets activated.
- Phase loss or Inadequate Supply Voltage Protection - To enter the error state: UV and OV LEDs flashes when voltage is lower than the nominal operating voltage by 0.4 times, after 100 millisecond the device gets deactivated the relay, and relay LED is turned off.

Operating Instructions
▪ Voltage Fault Detection
If a voltage fault is detected during the relay reset/start delay countdown, the output relay will disconnect and the fault indication LED will light up.
▪ Normal Operation
During normal operation, the display shows real-time voltage and current values. If a voltage or current fault is detected, the output relay disconnects and the fault indication LEDs light up.
▪ Voltage Fault Recovery
When the input voltage returns to the hysteresis threshold (Hys) after a voltage fault trip, the relay resets automatically.
During the reset/start delay countdown, the fault indication LEDs turn off and the operating voltage and current values flash on the display.
▪ Current Fault Recovery
After the relay trips due to an overcurrent fault, it resets automatically.
During the reset/start delay countdown, the fault indication LED turns off and the operating voltage and current values flash on the display.
