Universal input conditioners/isolators accept a wide range of RTD, thermocouple, resistance, potentiometer, mA or voltage inputs, and offer current, voltage and/or relay outputs with programmable ranges and functions. Units can be configured by using a detachable programming module that also displays the input signal value, engineering units, output signal and relay status.
Universal Input Signal Conditioners / Signal Isolators
Category Selection
SCU Series Universal Signal Conditioners ... New!
Why do our New universal signal conditioners look just like our existing signal conditioners? AutomationDirect has worked with our manufacturer to re-launch our ProSense brand of existing universal signal conditioners under new part numbers (SCU-1400, SCU-1600, SCU-PDM1) that provide the same form, fit, function, and add Factory Mutual (FM) approval for hazardous locations, all at a lower price!
The existing 884114, 884116 and 884501 part numbers will be retired when our remaining inventory is depleted. Please consider the SCU-1400, SCU-1600 and SCU-PDM1 part numbers as direct replacements.
Universal Signal Conditioner Types
- SCU-1400 - mA or VDC analog output
- SCU-1600 - mA or VDC analog output, 2 relay outputs
- SCU-3100 - 2 relay outputs ... New!
- SCU-8400 - unipolar and bipolar input signals ... New!
- SCU-7900 - AC RMS current or voltage input ... New!
Universal Signal Conditioners Features
- Universal supply voltage, 21.6 to 253 VAC or 19.2 to 300 VDC, polarity insensitive
- 3-way isolation between input, output, and power
- Easy-to-use detachable LCD programming/display module SCU-PDM1 (sold separately, required for programming)
- Transfer configuration settings from one signal conditioner to another with SCU-PDM1
- Integral 35mm DIN rail mounting adapter
- Removable screw terminal blocks are keyed to ensure correct installation
- 5-year warranty
SCU-1400, SCU-1600, SCU-3100
Signal Conditioners
Provide the flexibility to convert, transmit, scale and isolate signals from a wide variety of process sensors and controller I/O. Programmable using the optional SCU-PDM1 detachable display front with available help text. Parameters include process calibration, signal simulation, password protection and error diagnostics.
- Accepts mA, VDC, thermocouple, RTD, linear resistance or potentiometer signal types
- Selectable input and output ranges, two-point field scalability, direct or reverse signal configuration
- Selectable output types
SCU-3100: two individually programmable relay outputs
SCU-1400: selectable direct or reverse acting mA or VDC analog output signal
SCU-1600: selectable direct or reverse acting mA or VDC analog output signal and two programmable relay outputs. - Auxiliary power supply output for 2-wire transmitters and 3-wire potentiometers
- Operation and relay status LEDs when display module is not installed (SCU-3100, SCU-1600)
- cULus, FM, and CE marked
Universal Signal Conditioners Overview
SCU-8400 Signal Conditioner
Provides the flexibility to convert, transmit, scale and isolate unipolar and bipolar signals from a wide variety of process sensors and controller I/O. The scalable input accepts signals up to +/-100 mA or +/-300 VDC with spans as low as 0.5 mA or 25 mVDC.
Features:
- Scalable unipolar or bipolar inputs of +/-100 mA or +/-300 VDC
- Selectable input ranges, two-point field scalability, and direct or inverse acting signal configuration to handle most any DC voltage or current conversion
- Available square root function
- Fast response time of < 20 ms is ideal for measuring torque, position, current and acceleration sensors
- Buffered voltage output option to handle high current load devices
- Auxiliary power supply output for 2-wire transmitters and 3-wire potentiometers
- cULus and CE marked
SCU-7900 Signal Conditioner
Provides the flexibility to accurately measure AC RMS current or AC RMS voltage. The selectable input can measure AC supply voltage up to 300 VAC RMS or AC current transformers up to 5A RMS. Programmable using the optional SCU-PDM1 detachable display front with available help text. Parameters include process calibration, signal simulation, password protection and error diagnostics.
- Accurate measurement of AC RMS voltage up to 300 VAC RMS or AC RMS current to 5 A RMS (Not suitable for VFD or non-sine wave sources)
- Selectable input and output ranges and two-point field scalability
- cULus and CE marked
SCU-PDM1 Programming
Display Module
Easily connects to the front of a Universal Signal Conditioner to enter or adjust module programming parameters and to display process data and status.
- For Use With: SCU-3100, SCU-1400, SCU-1600, SCU-8400, SCU-7900
- 4-line LCD display for visualization of process data and status: Line 1 shows input signal, line 2 shows units, line 3 shows analog output or user defined text and line 4 shows communication and relay status
- Snaps onto the front of the universal signal conditioners
- Can be moved from one module to another and download the configuration of the first transmitter to subsequent transmitters
- Can be installed or removed with signal conditioner powered or not
- Required for programming all SCU Series Universal Signal Conditioner models
