Relay current monitoring relays

Current control relays are an important group of control and control devices in industrial automation lines. They eliminate the risk of damaging network elements. They also enable a relatively simple control and supervision of the current flowing in the circuit and on its individual segments. Such signals can be used to warn the operator or interrupt the operation of the production line. At the same time, the user receives information about emergency or undesirable situations via the LED lighting system.

When network monitoring and control is important

Relays for relay current monitoring are indispensable wherever protection of electrical systems is needed and the operation and stability of the installation are essential. Current control relays now offer highly effective monitoring and control of errors in the network, giving the user the expected confidence that the operation of the entire system is under constant supervision. Network monitoring and control becomes extremely effective as a result.

Current control relays have a current over / under current monitoring function. Relays with a memory function are more and more often chosen. These devices can be adapted to different current ranges. Current control relay indications can be used for remote diagnostics of the device.

Current control relays: types

AC current control relay in one phase allows to control the current and adjustment of voltage fluctuations AC / DC in the range from 20 mA to 5A (with overload up to 10A) with the possibility of setting the activation threshold, starting time, delay time . It is used to monitor alternating current in one phase. The maximum current can be set in the range from 0.1 <IN <1.0, and the minimum current in the range from 0.05 <IN <0.95. The device has the ability to set the switch-off delay time. The modular housing and 230 VAC power supply allow it to be used in typical applications and mounted on a standard installation rail.

Single-phase AC current control and DC current - allows you to control DC and AC current in one phase. Inrush current insensitivity time setting allows us to control devices with higher inrush current. It has the ability to delay shutdown. Three-phase voltage control relay - allows you to control the voltage in three phases, monitors phase sequence changes, phase loss and allows for the recovery of voltage recovery. It is a relay for monitoring the AC current value in a 3-phase network with adjustable measurement thresholds.

Functionality of current control relays

The functionality of the relays offered by the manufacturers allows for various types of supervision. The possible settings (set using potentiometers) include:

  • Over - control of the maximum current value

  • Over + Latch - control of the maximum current value with error memory

  • Under - supervision of the minimum current value

  • Under + Latch - supervision of the minimum current value with error memory

  • Win - window function current supervision between MIN / MAX values

  • Win + Latch - current supervision in a window function between MIN / MAX values ​​with error memory

  • Control of the AC current (frequency range 16.6 ... 400 Hz) in one phase and at the same time the value of the direct current.

Installation of current control relays, and the structure of the installation

Current control relays are mounted directly on a 35 mm rail according to PN-EN 60715. They can be installed in cabinets via mounting plates. The working position is free. The relay housing is made of a self-extinguishing plastic. The design of the current control relay provides galvanic isolation from the power supply through a galvanic barrier in the internal power transformer.

The transition circuit for the relays can be characterized as follows: two switched contacts, maximum AC1 switching power, if the distance between the relays is less than 5 mm - 750 VA (3 A / 250 V AC), and when it is greater than 5 mm - 1250 VA (5 A / 250 V AC). High quality and reliability of work allows for the construction of reliable systems operating in various configurations.
