Signal Conditioners and 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

Your benefits 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
• 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).

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.

Your benefits with our 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).

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

Your benefits 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
