Signal Conditioners
Signal conditioners, transmitters, and optical isolators eliminate ground loops, isolate noise issues, and convert signals to required types and ranges. Point-to-point wireless devices offer long-range signal transmission, and limit alarms provide discrete outputs based on an analog input value.

Signal Conditioners
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.

DC Voltage, Current or Potentiometer Input
Signal conditioners isolate analog voltage and current signals, or provide bipolar/unipolar voltage conversions with isolation. Universal models accept a wide range of RTD and thermocouple inputs. Many units can be configured via DIP switches, or a programming module, depending on model.
Universal Input
Newest Additions!
- Define Instruments Javelin, TM, and Sentry series signal conditioners
Universal input conditioners/isolators accept a variety of inputs and provide current, voltage, frequency, or relay outputs with programmable ranges and functions. They are configurable via a programming module that displays the input signal, engineering units, output signal, and relay status.
Temperature Transmitters
Newest Additions!
- Define Instruments signal conditioners and head-mount programmable temperature transmitters
- ProSense XTD2 and more XTH2 series fixed-range temperature transmitters
Temperature transmitters support many sensor types and deliver outputs ideal for extending signals to controllers. Mounting options include DIN rail, connection head, and inline styles. Fixed range and programmable options are available; select models feature IO-Link or HART communication.
Frequency Input
Newest Additions!
- Define Instruments Sentry series signal conditioners
- ProSense SC6 series high-density pulse isolators and frequency input signal conditioners
High-density 6mm and universal signal conditioners handle a wide range of frequency inputs and support multiple sensor types, delivering isolated, fast-response performance. Models offer analog or relay outputs, while select units add scalable outputs and a square root function.
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)
Newest Additions!
- Define Instruments Sentry series signal conditioners
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 interface to other process equipment.
High Density Signal Conditioners
Newest Additions!
- ProSense SC6 series high density pulse isolators and frequency input signal conditioners
High-density signal conditioners provide reliable signal conversion for industrial applications. They feature ultra-slim 6mm housings, signal isolation, DIP switch setup, FM-approved models, support for voltage, current, temperature, pulse, and frequency inputs, and a variety of output options.
Point to Point Wireless I/O
Point-to-point wireless I/O devices ensure reliable signal transmission over long distances (up to 0.9 miles, extendable to 14.9 miles with repeaters) where cabling is difficult or costly. They support a variety of analog input types and offer scalable 4-20mA outputs and versatile discrete I/O.
Sensor Signal Converters
New!
Patch cable and terminal-block signal converters adapt discrete sensor signals for reliable operation across industrial applications. Compact and easy to install, they support complementary outputs, PNP/NPN conversion, output inversion, pulse extension, and configurable AND/OR logic.
Signal Conditioners Accessories
Accessories and spare parts for signal conditioners include replacement terminal blocks; LCD displays for select models; configuration software for programmable units; configuration cable (for use with software); and a detachable programming/display module for some models.
