For systems that rely on precise measurements, safeguarding control signals from degradation and interference is vital. Even with the best equipment, signals can be degraded if the equipment is not properly installed or is not protected by signal conditioners/signal isolators. This selection of signal conditioners, transmitters, and optical isolators solve ground loop problems, isolate noise issues, convert signals to desired levels and types, and allow longer cable runs. Limit alarms take analog inputs and provide low-limit, high-limit, or other discrete outputs based on the input value. Point-to-point wireless I/O provides an easy solution for connecting to remote/isolated devices.

Signal Conditioners Buying Guide
Signal Conditioners with DC Voltage, Current, or Potentiometer Input
These signal conditioners isolate analog voltage and current signals or provide bipolar/unipolar voltage conversions with isolation. Various inputs are supported including current, voltage, RTD, and thermocouple, with current, voltage, frequency, and/or relay outputs. Many units can be configured via DIP switches, or a programming module, depending on model.
Signal Conditioners with Universal Input
Universal input conditioners/isolators accept a variety of inputs and provide current, voltage, frequency, and/or relay outputs with programmable ranges and functions all in one unit. They are configurable via a detachable programming module that displays the input signal, engineering units, output signal, and relay status.
Temperature Transmitters
Newest Additions!
- WAGO JUMPFLEX® 857 series high density temperature transmitters
- Endress+Hauser iTEMP series temperature transmitters
Thermocouple and RTD transmitters accept popular sensor types and measurement ranges and provide current outputs. Universal models also accept millivolt, current, and potentiometer inputs; select models offer a frequency output. These units are ideal for wiring and extending signals to controllers.
Signal Conditioners with Frequency Input
Frequency signal conditioners accept frequency signals up to 100kHz from a variety of sensor types and provide unipolar or bipolar analog (current/voltage), relay, or frequency (up to 100kHz) outputs. An optional square root relationship between the input and output is also available for flow measurement applications.
High Speed Optical Isolators (Encoder Input)
Optical isolators connect encoders to PLCs, servo drives, and other devices. They solve electrical noise issues, convert encoder signal types or voltage levels, provide multi-channel high-speed isolation for other sensor types, and can be used as repeaters for long cable runs.
Limit Alarms (Analog Input, Relay Output)
Limit alarms accept analog inputs and provide low-limit, high-limit, or other discrete output indications based on the input value. Voltage or current input signals are compared to trip points configured via DIP switches or a programming module. Relay outputs can be used to interface with other process equipment.
High Density Signal Conditioners
Newest Additions!
- WAGO JUMPFLEX® 857 series high density signal conditioners and temperature transmitters
6mm-wide signal conditioners are space-saving units that provide conversion of standard voltage and current signals, bipolar signals, thermocouples and RTDs, with isolation to eliminate ground loop problems. Models include single-, two-channel, and signal splitter styles.
Point-to-Point Wireless I/O
New!
Point-to-point wireless I/O is ideal for industrial settings where hard wiring is impractical, such as long distances, physical obstacles, or moving equipment. It creates a dedicated, bidirectional radio link between a pre-paired set of wireless units, enabling reliable transmission of analog or digital signals with easy deployment.
Signal Conditioners Accessories
Accessories and spare parts for signal conditioners include replacement terminal blocks, configuration software for programmable units, configuration cable (for use with software), and a detachable programming/display module for select models.
