Signal Conditioners and Isolation Amplifiers

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. 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.

Advantages:

• Signal acquisition of DC and AC voltages up to 300 VAC/VDC using modules that are just 6 mm wide
• AC currents up to 400 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).

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

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

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).

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).

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).

The signal conditioners are all user-friendly and easy to configure using WAGO's interface configuration software.

Advantages:

• Simulation of input and output parameters (2857 Series)
• Automatic module recognition
• Configuration and visualization of process values
• Parameterization of the digital switch output (threshold functionality)
• Communication via WAGO USB Service Cable (750-923) or WAGO Bluetooth® Adapter (750-921), pluggable on both series

The free JUMPFLEX® -ToGo App brings the power of PC-based configuration software to your Android mobile device.

Advantages:

• Configuration of input and output parameters at the touch of finger
• Simple display of configuration data and current value
• Communication via WAGO Bluetooth® Adapter (750-921)

The removable display can be quickly and easily attached to the housing. This unique feature includes an innovative capacitive touch panel for intuitively configuring devices. The multicolor display switches between orange, red, green and white depending on the device's 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 and changes.

Advantages:

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