Signal Conditioners

Red Lion® provides a broad selection of signal conditioners for frequency, temperature and process applications. Our signal conditioners range from dedicated to universal models capable of accepting over 100 inputs, which allows these units to be used almost anywhere.

Frequency Input

IFMA Series

Red Lion's IFMA series accepts frequency inputs from 1 Hz to 25 KHz and provides an analog output proportional to the input signal. User selectable current/voltage output allows for easy deployments in many applications. The IFMA series includes universal input and 3-way isolation. Learn more.

IFMR Series


The IFMR series from Red Lion accepts frequency inputs from .1 Hz to 25 KHz and provides outputs including over-speed, under-speed or zero-speed detection. With the built-in single relay output, the IFMR series can be set to trip anywhere from .1 Hz to 25 KHz. This series supports universal input, alarm latching and resetting. Learn more.

Temperature Inputs

IRMA Series

Measuring RTDs at a distance can be a challenge, but with the IRMA series from Red Lion, remote RTD monitoring is easy.  The IRMA series accepts 2, 3 and 4 wire sensors and converts the signal to a 4 to 20 mA output. Several options are available on the IRMA series including loop powered and sensor break detection. Learn more.

ITMA Series

Red Lion's ITMA series makes remotely monitoring thermocouples or millivolt signals easy. The ITMA series accepts industry standard thermocouple inputs and converts the signal to a 4 to 20 mA output. Available options include loop powered and sensor break detection. Learn more.

Process Inputs

IAMS Series

The IAMS series from Red Lion is our most versatile signal conditioner product line. It can accept over 100 different combinations of signals, including process, DC current, DC voltage, thermocouples, RTDs, potentiometers, and linear resistance signals allowing most devices to be connected to most sensors. Our IAMS series supports setpoints, analog output, 3-way isolation, and a programming module. Learn more.

IAMA Series

Red Lion's IAMA series features over 100 analog I/O conversion combinations and offers linear or square root extraction models. The IAMA series is perfect for process control applications and supports easy set-up, 3-way isolation, and universal input power. Learn more.


Red Lion's IAMA0006 series signal conditioner features an ultra-slim, small form-factor design. Supporting 35 I/O conversion combinations for the most common industrial applications. With its .244" (6 mm) overall width, this slim-line model can fit almost anywhere. The IAMA0006 offers 3-way analog isolation and DIP switches for easy configuration. Learn more.

AIMI Series

Red Lion’s AIMI series provide passive electrical isolation and processing of analog 0 to 20 mA, or 4 to 20 mA current signals. The AIMI is loop powered and perfect for connecting control and process equipment. Learn more.

AFCM Series

The AFCM series of signal converters, from Red Lion, convert process current/voltage signals to user definable output frequency signals. Providing simple operation, the AFCM series is available with 0 to 5 Hz or 0 to 10 KHz models. Learn more.
