Absolute Process Instruments Signal Conditioners
RSP Supply offers a full selection of Absolute Process Instruments (API) signal conditioners available at competitive prices. Signal conditioners play a crucial role in industrial automation and control, converting, isolating, amplifying, and filtering sensor signals for accurate measurement and reliable system performance.
Whether you’re measuring temperature, flow, pressure, or other analog inputs, API signal conditioners deliver precision and stability, ensuring that each signal is clean, isolated, and ready for processing by PLCs or controllers.
FAQs
What does a signal conditioner do?
A signal conditioner converts, amplifies, and isolates sensor input signals into readable outputs for PLCs or controllers, ensuring accurate and stable data.
What are the main functions of API signal conditioners?
They provide conversion, isolation, amplification, and filtering, improving measurement accuracy and protecting control systems from electrical noise.
What is the difference between a signal isolator and a signal converter?
A signal isolator protects control devices from electrical interference, while a signal converter changes one signal type into another format for system compatibility.
What are the advantages of API dual-channel isolators?
They offer two independent, fully isolated input/output channels, reducing noise and ensuring stable signal performance in multi-sensor systems.
Where are API signal conditioners used?
They are used in industrial automation, process control, manufacturing, and instrumentation systems to ensure reliable, noise-free signal transmission.

Reliable Conversion and Isolation
API signal conditioners come in two main configurations:
- 1-Channel Converter/Isolator/Transmitter – Provides one input and one output with full 3-way isolation between input, output, and power.
- 2-Channel Transmitter and Isolator – Factory-configured for two frequency input signals and two independent DC output signals, offering full isolation and noise protection on each channel.
Each unit features independent power, input, and output circuits, and each channel includes filtering, amplification, and isolation to ensure precision and safety in complex systems.
Signal Conditioning Functions
Signal conditioning includes several key functions that improve system reliability and data accuracy:
- Signal Isolators – Protect sensitive PLCs and control hardware from voltage spikes, ground loops, and electrical noise.
- Signal Converters – Change one type of input (e.g., RTD or thermocouple) into a different output signal readable by a controller.
- Signal Amplifiers – Increase signal strength and signal-to-noise ratio for precise monitoring and control.
- Signal Splitters – Duplicate signals so they can be sent to multiple destinations (e.g., two PLCs) without degradation.
API signal conditioners combine all these functions to enhance data integrity, protect instrumentation, and simplify complex control architectures.
