Current control relays

Current monitoring relays are monitoring relays designed to protect electrical systems. Their role is to ensure the stable operation of the installation. It is a group of control and control devices that enable a relatively simple supervision of the current flowing in the circuit, while informing about the occurrence of emergency situations or undesirable surges and decays of current.

The function of the phase monitoring relays is to control the value of the current flowing in the electric circuit. These types of relays allow the contacts to be switched when the permissible current value is exceeded. It is a product without which home automation could not function properly. Thanks to the current relays, it is possible to react to such situations as, for example, the engine running without load or working with too heavy load.

Action

Current control relays can be used to control both direct and alternating currents. By means of the set lower and upper operating limits, they enable the protection of devices against overload or underload. The mechanism is controlled by a potentiometer on which the minimum and maximum thresholds of the tripping current are set. In the event of a drop in the current value below the set threshold, it will automatically open the contact. In a situation when the value of the current intensity exceeds the setting threshold, the contact will be closed with a pre-set time delay.

The relay usually signals its correct operation with the green light of the indicator lamp. The exceeding of the setting threshold value is signaled by the lighting of the red control lamp.

In the event of an increase in the flow rate, the contacts close, which automatically open when the threshold is lowered again to a minimum. The time of reaction and return to the correct setting takes up to a few seconds, depending on the setting of the relay. These relays are most often used in the case of a large number of devices that require the intensity to be adjusted to their parameters.

Types of current control relays

Current monitoring relays monitor direct or alternating current, supervision in one or three phases. The selected functions allow a large span and variety in the control of the tested circuit. An additional advantage of some models of current control relays is current reading of the current value. The main types of current control relays are:

  • relay to control the intensity of alternating current in one phase,

  • relay controlling the AC current in one phase and at the same time measuring the value of direct current,

  • DC current control relay,

  • relay for monitoring the AC current value in a 3-phase network with adjustable measurement thresholds.

Functionality of current control relays

Current control relays have the ability to set thresholds (MIN and MAX), with adjustable delay and start times, as well as functions (most often selected with a rotary potentiometer on the device body), such as:

  • OVER - control of exceeding the maximum value of current on the line,

  • OVER + LATCH control of exceeding the maximum current value with error memory,

  • UNDER control of a drop below the set minimum current value,

  • UNDER + LATCH control of a drop below the programmed minimum current value with error memory,

  • WIN control that the current is maintained in the window between the set MIN and MAX limit values,

  • WIN + LATCH checking that the current is maintained in the window between the MIN and MAX limits with error memory.

It is worth using current control relays, because they guarantee safety during use and ensure ongoing monitoring of the condition of working machines.
