Relays and timers

Industrial Relays – R2N, R3N, R4N – Relpol

The offer of Relpol S.A. has been extended by new electromagnetic relays R2N, R3N, R4N which are modernized versions of the relays R2, R3, R4 still available in the offer. The new relays are extinguished by a modern design, higher quality and high functionality. They are manufactured in a modernized technology.

Major changes in the design of the relays are the improvement of the functionality of the mechanical indicator, the application of electronics in the SMD technology for the additional features L and D, the improvement of the efficiency of the electromagnet and the strengthening of the insulation in the area of the contact plate.

The R2N, R3N, R4N relays maintain the conformity of dimensions, raster of the terminals of contacts and coils and technical data with the respective R2, R3, R4 relays. They are available with similar additional features.

Isolation and measuring transducer STR/BTR - HSB

For the conversion of a standard electrical signal into another standard signal or/and electric isolation, the STR/BTR isolation transducer from HSB Electronics uses the terminals A1 and A2 for connection to 24VAC/DC or 230VAC. The green LED indicates the connection to the power supply, which must be continuously connected to the transducer.
 
The STR/BTR transducer acquires a standard signal 0(4)...20mA/ 0(2)...10V and converts it into an independent current or voltage signal. The measuring circuit is electrically isolated from the power supply. The desired configuration is selected with the DIP switches on the relay´s front panel. The STR/BTR isolation transformer has three-way isolation.

Measuring Over Current Relay SIR - HSB

The measuring over current relay from HSB monitors an AC or DC current connected to the terminals B1/B2. If the current is higher than the value selected with potentiometer I>, the relay switches to its working position (yellow LED is on). The relay switches back to its rest position as soon as the monitored current is below the adjusted value plus the adjusted hysteresis.
 
The SIR current measuring relay from HSB has two separate inputs for DC and AC supply. For a 230VAC power supply use the terminals A1/A2. For a 24V AC/DC power supply use the terminals A3/A2. The green LED indicates the connection of the power supply. Continuous presence of the power supply (A1/A2 or A3/A2) is required for measuring. The measuring circuit is galvanically isolated from the supply. The response time can be adjusted between 0 ... 10 seconds. The relay continuously monitors the rectified value of the input signal.

Miniature Relays R2/R4 - Relpol

Relpol miniature electromagnetic relays R2 and R4 type are suitable for industrial applications and environments, where reduced space assumes a great importance.

According to European standards, a relay is defined as an electrically controlled device that opens or closes electrical circuits for operation affectation of other devices in the same or in different electrical circuits. For this reason, the relay assumes a significant importance in contemporary industrial processes. Tens of thousands of relays now operate throughout the world.

Optocouplers – Murrelektronik

Minimum space – maximum functionality.

MIRO – the coupling module in terminal block format.

Coupling modules in the form of relay and opto-coupler modules are indispensable in controller and system construction. Coupling modules are needed for signal amplification, signal adaptation, potential separation, potential-free transfers to other parts of the system and for increasing interference immunity.
Using the MIRO range of modules will cut your costs and block out interference and overvoltage from PLC boards and construction cards. MIRO interface modules will increase the operational reliability of your system and reduce the size of your switch cabinet.
