Signal Conditioners / Signal Isolators

• The FC series signal conditioners offer 1500V isolation between the input and output to help eliminate electrical noise.
  
  
• Universal isolated signal conditioners provide signal/ground loop isolation and accept milliamps, volts, RTD, thermocouple or potentiometer inputs.
  
  
• These AutomationDirect supplied signal conditioners are ideal for use with PLCs, loop controllers, digital displays and many other applications requiring an isolated or analog signal.
  
  
• Signal conditioners are also sometimes referred to as signal amplifiers, isolation amplifiers, signal transmitters, ground loop isolators, 4-20ma converters, 4-20ma signal isolators or 4-20ma loop isolators.
  
  

Are ground loops causing you to have signal integrity problems?

• Signal integrity can be greatly impacted by poor shielding or wiring practices. The biggest factor is often ground loop errors (ground noise).
  
  
• Signal or ground loop isolation is one way to eliminate ground loop errors caused by ground noise and other such signal interference problems. Signal isolators use one of many electronic methods to interrupt the connections between two grounds while passing the correct signal with little or no loss of accuracy. Without a way for ground currents to flow, these currents can't induce signal errors caused by ground noise.

FC Series Signal Conditioners Overview

Universal Series Signal Conditioners Overview

• The FC-11 is a DIN-rail or side mount, 4-20 mA input / output signal conditioner with 1500 VDC isolation between input and output and has a user-selectable factory calibration.
  
  
• The output is also calibrated with OFFSET (zero) and SPAN (full scale) adjustments. The OFFSET and SPAN have an adjustment range of ± 2% of full scale input.
  
  
• The FC-11 isolated input/ output signal conditioner is useful in eliminating ground loops or sinking/ sourcing issues when interfacing to PLC analog input modules and solves many types of configuration problems.

• The FC-33 is a DIN-rail mount, selectable input/ output signal conditioner with 1500 VDC isolation between input and output and 1500 VDC isolation from 24 volt power and input/ output. The field configurable input/ output types allow a wide ranging capability for 0 - 5 V, 0 - 10 V, 0 - 20 mA, 4 - 20 mA.
  
  
• The FC-33 has user selectable factory-calibration, but also has OFFSET (zero) and SPAN (full scale) adjustments of the output signal. The OFFSET (zero) has an adjustment range of 0 to 25% of full scale input, the SPAN (full scale) has an adjustment of -20% to 2%.
  
  
• The FC-33 field configurable isolated input/ output signal conditioner is useful in eliminating ground loops and interfacing sensors to our PLC analog input modules. The FC-33 has 3 way isolation that solves many types of configuration problems.

• The FC-R1 is a DIN-rail mount, Resistive Temperature Detector, signal conditioner. FC-R1 is non-isolated, 3-wire RTD which converts to linearized 4 - 20 mA current loop.
  
  
• The FC-R1 has user selectable,CU10 (10 Ohm copper), PT100 (100 Ohm platinum), PT1000 (1000 Ohm platinum) RTD input, but also has OFFSET (zero) and SPAN (full scale) adjustments of the output signal. The OFFSET and SPAN have an adjustment range of ± 2% of full scale input.
  
  
• The FC-R1 field configurable input signal conditioner is useful for interfacing RTD sensors to our PLC analog current input modules. Use shielded RTD's whenever possible to minimize noise on the input signal.

• The FC-T1 is a DIN-rail or side mount, thermocouple/ mV input signal conditioner with 1500 VAC isolation between input and output. The field configurable input allows a wide ranging capability for J,K,E,R,S,T,B,N,C type thermocouple and -156.25 mV to +156.25 mV.
  
  
• The FC-T1 has built-in self-calibration, but also has OFFSET (zero) and SPAN (full scale) potentiometers for adjustment of the output signal. The FC-T1 is also equipped with cold junction compensation (CJC) circuitry to provide an internal ice-point reference.
  
  
• The FC-T1 field configurable thermocouple/ mV input signal conditioner is useful in eliminating ground loops (ground noise) and interfacing sensors to our PLC analog input modules. If your requirements are just for one channel of temperature you can add the signal conditioner to your 4-20 mA input modules. Or, if your requirements are for a single millivolt signal source, you can add this input to your analog module.

• The 884114 and 884116 are DIN-rail or wall mount universal signal conditioners and signal isolators for RTD, Thermocouple, Ohm, potentiometer, mA or voltage inputs.
  
  
• The 884114 has current and voltage output. The 884116 has current, voltage and two relay outputs.
  
  
• Programmable Signal Conditioners - The 884114 and 884116 signal transmitters are programmable using the optional 884501 detachable display front with available help text. Parameters include process calibration, signal simulation, password protection and error diagnostics.
  
  
• The 884114 and 884116 signal conditioners provide linearized temperature measurement with an RTD or thermocouple sensor. Linear resistance measurement is converted to a standard current/voltage signal from devices such as solenoids, butterfly valves or potentiometers. The 884114 and 884116 are suitable for SIL 2 installations.
