Conditionneurs de signaux de courant, de tension et de puissance
Outre les conditionneurs de signaux de courant et de tension qui enregistrent les courants et les tensions continues et alternatives, cette gamme impressionnante comprend également un conditionneur de signaux de puissance qui peut mesurer le courant et la tension en parallèle, les convertir en puissance et les sortir sous forme de signal analogique standard. En outre, le conditionneur de signal de WAGO pour les bobines Rogowski offre une solution pour la modernisation des systèmes existants. Il n'est donc pas nécessaire de déconnecter le conducteur sous tension.
Avantages :
- Acquisition de signaux de tension continue et alternative jusqu'à 300 VAC/VDC à l'aide de modules d'une largeur de 6 mm seulement
- Courants alternatifs jusqu'à 400 A via la bobine de Rogowski
- Fonction de filtrage commutable pour éviter les interférences de signaux
- Une sortie de signal numérique réagit aux limites librement configurables de la plage de mesure (ce qui permet de l'utiliser comme relais à seuils - avec délai d'activation/désactivation).
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
Advantages:
- 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
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.
Advantages:
- 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

Potentiometer Signal Conditioners
WAGO’s potentiometer position signal conditioners record resistance signals, e.g., from potentiometers, and convert them into an analog standard signal.
Advantages:
- Signal acquistion 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).

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.
Advantages:
- 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).

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 isolation amplifiers
Advantages:
- 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).
