Isolation Amplifiers

Isolate, amplify, filter or convert: WAGO’s isolation amplifiers handle a large number of functions in industrial applications and provide secure and error-free signal transmission.

The range of isolation amplifiers provides the right solution for every application:

  • With a power supply: isolation amplifiers (permanently configured), isolation amplifiers (configurable), universal isolation amplifiers, bipolar isolation amplifiers, repeater power supplies, signal splitters
  • Without a power supply: passive isolators, loop-powered isolators

Your benefits with WAGO's isolation amplifiers:

  • Galvanic isolation between input/output/power supply
  • Zero and span adjustment to compensate for error or signal shifts
  • Switchable filter function to prevent signal interference
  • Reliable protection of the input circuit against overcurrent (857-409, 857-402, 2857-401)
  • A digital signal output (DO) reacts to freely configurable measurement range limits (this allows use as a threshold value switch – with activation/deactivation delay).

Frequency Signal Conditioners

WAGO’s frequency signal conditioners record 0.1 kHz to 120 kHz signals from NAMUR, NPN or PNP sensors and convert the frequency into an analog standard signal.

Your benefits with WAGO's frequency signal conditioners:

  • Signal acquisition from NAMUR, NPN or PNP sensors
  • Frequency range: 0.1 … 120 kHz
  • Fault signaling: Wire break/short-circuit detection for NAMUR proximity sensors
  • Signaling measurement range underflow/overflow

Temperature Signal Conditioners

With WAGO’s temperature signal conditioners, signals from Pt, TC, Ni, KTY and RTD sensors and resistors can be recorded and converted into an analog standard signal on the output side. Whether a resistive temperature device or a thermocouple is used depends on factors such as the maximum temperature range, the installation’s environment and the required measurement accuracy:

  • Resistive temperature device (RTD): Temperature range up to 850°C, high accuracy
  • Thermocouple (TC): Temperature range up to 2320°C, better response time

The benefits of our temperature signal conditioners for you:

  • Signal acquisition of Pt, TC, Ni, KTY and RTD sensors and resistors up to 4.5 kΩ (e.g., Pt100 sensors)
  • 2-, 3- and 4-wire connection technology
  • Fault signaling: Wire break/short-circuit detection of the sensor
  • Signaling measurement range underflow/overflow

Threshold Value Switches

WAGO’s threshold value switches monitor various measurement signals such as temperature, current or voltage. If a value falls above or below a limiting value setting, emergency stops or alarms can be triggered, for example. In addition to threshold value switches for analog signals, WAGO also offers RTD threshold value switches for resistance temperature sensors and potentiometers, as well as TC threshold value switches for thermocouples, allowing both signal monitoring and measurement.

Your benefits with WAGO's threshold value switches:

  • Input/output response simulation (2857 Series)
  • Relays as threshold value switches (e.g., activation/deactivation delay)
  • A digital signal output (DO) reacts to freely configurable measurement range limits (this allows use as a threshold value switch – with activation/deactivation delay).

Potentiometer Signal Conditioners

WAGO’s potentiometer signal conditioner records resistance signals (e.g., from potentiometers) and converts them into a standard analog signal.

Your benefits with WAGO's potentiometer signal conditioners:

  • Signal acquisition from potentiometers and resistors
  • Automatic potentiometer identification
  • Configurable input and output parameters

Current and Voltage Signal Conditioners and Power Measurement Modules

Besides current and voltage signal conditioners which record DC and AC currents and voltages, this impressive range also includes a power measurement module that can measure current and voltage in parallel, convert them to power and output them as an analog standard signal. Additionally, WAGO’s signal conditioner for Rogowski coils offers a solution for retrofitting existing systems. Thus it is not necessary to disconnect the live conductor. The new WAGO 3-Phase Power Measurement Module measures all relevant parameters in a three-phase supply network – voltage, current, power, harmonics, etc. – from within the control cabinet.

Your Benefits:

  • Signal acquisition of DC and AC voltages up to 300 VAC/VDC using modules that are just 6 mm wide
  • AC currents up to 4000 A via Rogowski coil
  • Switchable filter function to prevent signal interference

The 3-in-1 Solution – in One Device

New 1-Phase Power Measurement Module for Current, Voltage and Power Measurement

The new single-phase power measurement module is a true multi-talent that directly measures both DC and AC currents up to 8 A, as well as DC and AC voltages up to 500 V. Furthermore, measured variables such as current, voltage, all types of power (3-in-1) and many more can be flexibly configured and evaluated – in the configurator or directly on the device display. Therefore, this new module allows many current and voltage measurement requirements to be met in both industrial and transportation applications.

It also monitors, reports and displays signal statuses with up to two switching thresholds and provides these statuses to a higher-level PLC via an analog or serial interface. For use of this power measurement module as a current, voltage or power threshold switch, a relay and digital output are integrated.

Service and Maintenance with Transparency

Who thinks about service and maintenance when using process technology systems? Analog signal conditioners and isolation amplifiers are well established in process technology. In addition to galvanic isolation, they enable the simple and economical adaptation of measuring technology signals for further processing at the control level. Following a significant reduction in size to a 6 mm installation width and the use of DIP switches, it is, however, high time for additional innovations in their configuration. Why not consider an attachable display, PC software or a smartphone app? These could significantly support the commissioning, service and maintenance of the system technology.
