Connections and interface circuits

Today, modern equipment design requires a wide variety of components that can meet many challenges such as: Easy to use and repairs, low costs, safety and availability, and ease of design and use, etc. to face well and resolve them. In many industries, electrical signals have conditions that cannot be connected directly to signal pickup and measurement equipment. Sometimes the signal amplitude is too high or too low, sometimes the signal received is not of the type accepted by I / O cards and modules, sometimes the signal carries noise, and finally sometimes the signal may carry voltage or current.

In all these cases, the signals need to be corrected before being received by the PLC and Remote I / O cards and modules. This is done by signal correctors. The German company WAGO, of which Patsa Industry is the official representative in Iran, offers a wide range of facilities to users and various industries by offering various products, so that they can convert and correct signals according to the standards related to each industry.

WAGO interface modules come in a variety of designs, such as plug-in interface modules, slim relays and optocouplers, switching power supplies, and many signal rectifiers. Ideal solutions to these challenges and ensure safe isolation. are. In addition, the ability to configure signal correction modules allows the user to use a single module for different input and output signals with different amplitudes. These modules can be configured in several ways: PC-based software, mobile applications and even deep switch for hardware configuration. This variety makes the user feel more comfortable while working with these products.

Isolated signal rectifiers and amplifiers:

Isolation, amplification, filtration and signal conversion are the most important operations performed by WAGO signal correctors. These features are doubly important when we know that these WAGO products have the safety standard DIN EN 61010-1, work in a wide operating temperature from -40 to +70 degrees Celsius, and finally using the software, the application Mobile phones, screens and deep switches are configurable.

Converting wide voltage ranges to voltage, voltage to current, current to current and current to voltage are some of the uses of signal correctors. In many cases the signals generated by the sensors either do not match the type of signal acceptable by the input / output cards and modules or are not in the standard signal range. In such cases, signal correctors can be used. Many signals have a frequency range that requires the rectifier filter bandwidth to cover this frequency response well. Adjustable filters in WAGO rectifiers solve this problem well.

Extremely high currents (in the range of 1000 amps and above) can be measured and converted via Rogovsky coils and WAGO high current rectifiers and then evaluated and monitored by the input modules of a PLC. Sometimes it is necessary to use a signal corrector for a variety of signals with different ranges. WAGO has also provided a solution to this problem. In this way, by using the deep switches on the correction modules, in addition to providing a variety of inputs and outputs for a corrector, they also provide easier and easier use for the operator and make him work with software. Apps that sometimes need to be learned and trained are emptied, and the operator can simply apply the desired conditions by changing the status of the deep switches.

Relays and optocouplers

Using its wide range of relays and optocouplers, WAGO offers comprehensive solutions for a variety of applications in a variety of industries.

Advantages of using this equipment:

  • Wide range of choices between couplers and relays

  • Switch loads from 1mA to 16A
  • Wide range of accessories such as jumpers, markers and system cables
  • Ease of use and service and support

Socket-based relays (socket-out) are the best solution for switching applications in both industry and process automation. These modules can be used for both two-pin switching as well as for switching currents up to 16A.

Advantages of these relays:

  • Very simple and basic replacement of damaged relays.
  • Very compact design with a thickness of 15mm
  • Connect the wire without the need for additional equipment and simply by pushing the wire into the terminal

Miniature relays and optocouplers with their very low thickness significantly reduce the space required in electrical panels. Among the features of this category of products are:

  • Different AC and DC relays

  • Ability to install the jumper from the front of the module to fit other WAGO I / O modules
  • It has an LED signal status display
  • Use of Cage Clamp spring terminals

WAGO SSR relays are a suitable recommendation for applications that have switching speed and frequency. Among the features of these relays are:

  • Replaceable and detachable SSR central module
  • Structural similarity of relays with other WAGO products that allow them to be connected and connected to each other
  • Establish a connection without the need for special tools and simply by pressing the wire into the terminal
  • Certified EX for Zone 2

Electrical interface circuits and equipment are mainly used to change electrical signals, including changing voltage and current levels, changing the type of signal (DC to AC and vice versa), and protecting against sudden changes in signals. Accordingly, the range of these products is very wide and has a wide variety. Among the products of this group, the following can be mentioned:

Relays and optocouplers

The purpose of using these products is to transmit electronic commands to electrical and power circuits. The main products of this group are relays. Different relays with different current carrying capacities, different disconnection and connection speeds and different Form Factors will expand the selection range for customers.
