Wilkerson Instrument Co. DC Isolated Signal Conditioners are proprietary designs which are manufactured in Lakeland Florida USA.

Our DC Isolators are available in 5 primary mounting and case styles for ease of use and process design applications. Most models are available in Voltage or Current Inputs and Outputs. Selection of industry standardized 4-20mA and 0-10V as well as a wide range of customer specific Inputs and Outputs are available. Several field adjustable (4380) models which allow users wide selections of inputs and/or outputs are also available.

Our DC Isolators are Factory calibrated to the customer’s specifications at no extra cost and all field adjustable models can be changed in the field with the use of internal jumpers or a factory configured plug-in range card (for SR Series models). Some trim pot adjustment may be necessary for field calibration. (See individual product specifications for more information)

Process monitoring and control engineering applications require their input signals to be free from electrical noise and standardized to prior levels before input into data acquisition and control systems such as PLCs or display panels. The instrumentation utilized will usually involve several steps beginning with filtering, amplifying, isolation and then signal conditioning.

The isolation phase is where the products “DC Isolators” draw their name and each variety of Isolator provides a specific function prior to its signal being delivered to the proper control system device or display. Signal converting takes the raw input signal and provides an isolated proportional output signal, such as 4-20mA, and then transmits this signal to the control system device.

Some signal conditioners perform specialized functions such as integration, pulse-width modulation, totalization, linearization, and other math functions to the transmitted signal. Due to the variety of different specialized functions DC Isolators can provide, the common industry names for them can vary. Signal Transmitters, 4-20mA Transmitters, Isolators, Ground Loop Isolators, 4-20mA Isolators, Analog Signal Conditioner and Converters, and Analog Signal Isolators are all common names depending upon which industry or technical staff is speaking about the product or control process application.

Installation of DC Isolators poses several challenges for maintaining signal strength and signal integrity. Poor signal quality and ground loops can be common faults that must be overcome with proper wire shielding and grounds methods.
