Signal Conditioners and Isolation Amplifiers

Isolate, amplify, filter and convert: Signal conditioners and isolation amplifiers within the JUMPFLEX® family handle a large number of functions in various application areas and provide secure and error-free signal transfer – thanks to a comprehensive range of approvals for worldwide applications. The focus is on usability and absolute reliability.

WAGO's signal conditioners and isolation amplifiers maintain uniformity in the cabinet. This allows easy commoning of the supply voltage, eliminating the need for time-consuming wiring of the individual components. Designed for easy commissioning and operation, WAGO's signal conditioners and isolation amplifiers make everyday tasks easier because their design merges mechanical with electrical features.

Isolation Amplifiers

Flow Measurement with WAGO's 857-423 Signal Splitter

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 transfer.

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

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

Functions of Isolation Amplifiers

Your advantages with our 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
  • The input circuit is effectively protected 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).

Current, Voltage and Power Signal Conditioners

Light Monitoring with WAGO's 2857-550 Current Signal Conditioner

Besides current and voltage signal conditioners which record DC and AC currents and voltages, this impressive range also includes a power signal conditioner that can measure current and voltage in parallel, convert them to power and output them as an analog standard signal. Furthermore, the signal conditioner for Rogowski coils offers a solution for retrofitting existing systems. Thus it is not necessary to disconnect the live conductor.

Your advantages with WAGO's current, voltage and power signal conditioners:

  • 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
  • A digital signal output (DO)* reacts to freely configurable measurement range limits (this allows use as a threshold value switch – with activation/deactivation delay).

Temperature Signal Conditioners

Temperature Monitoring via Pt Sensor with WAGO's 857-801 Temperature Signal Conditioner

With WAGO's temperature signal conditioners, 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 situation 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

Your advantages with our temperature signal conditioners:

  • Signal acquisition of Pt, TC, Ni, KTY and RTD sensors and resistors up to 4.5 kOhm (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

Frequency Signal Conditioners

Speed Measurement via NAMUR Indicator with WAGO's 857-500 Frequency Signal Conditioner

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

Your advantages with our 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 switches
  • Signaling measurement range underflow/overflow

Threshold Value Switches

Temperature Monitoring via Threshold Value Functionality with WAGO's 2857-533 Resistance Threshold Value Switch

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 advantages with our 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

Resistance Measurement via Potentiometer with WAGO's 857-809 Potentiometer Signal Conditioner

WAGO's potentiometer signal conditioners record resistance signals, e.g. from potentiometers, and converts them into an analog standard signal.

Your advantages with our potentiometer signal conditioners:

  • Signal acquisition from potentiometers and resistors
  • Automatic potentiometer identification
  • Configurable input and output parameters
  • A digital signal output (DO)* reacts to freely configurable measurement range limits (this allows use as a threshold value switch – with activation/deactivation delay).

The multicolor display changes between orange, red, green or white depending on the 2857 Series’ current status. Integrated capabilities, such as the copy function, can transmit stored configuration data from one device to another of the same type. Passwords for protecting configured data may be assigned to prevent unauthorized access or changes.

  • Can be easily plugged into signal conditioners
  • Touch functionality via control panel
  • Automatic module recognition
  • Configuration and visualization of process values
  • Copy configuration data from device to device

*In order to increase the DO’s switching current, expand the DO with a relay. For example, a relay (857-359) can be snapped onto the rail next to it because the 857 and 2857 Series modules share the same profile. This output can be quickly and easily expanded to a 6 A switching current by simply using an adjacent jumper (859‑402).
