Analog Signal Conditioning & Isolation Modules

With an experience of over two and a half decades Canopus Instruments is considered as one of the biggest company committed to providing top quality analog device, signal conditioning unit around India. The Signal conditioning unit and analog device find applications where it is of prime importance to ensure liable performance.

The SIM μ 3.0 Series Analog Signal Conditioning & Isolation modules find applications where it is of prime importance to ensure reliable performance as well as safety while interfacing input/output analog signals of sensitive electronic Control & Measurement Systems with field devices such as sensors and actuators. The use of signal conditioners with isolation allows direct interface of far away field mounted devices with analog I/O channels of DCS, PLC based Control Systems, AC/DC Electric Drives, Indicators, Recorders, etc.

These modules eliminate occurrences of faulty measurements in process control equipment caused by ground loops. They are also necessary to protect the measuring equipment from noise and transients generated due to inductive load switching and other unpredictable electrical disturbances occurring in the field.

The SIM μ 3.0 modules are characterized by their fast response; improved noise rejection, superior long-term stability, & wide DC power supply range. These features make them an attractive choice for AC & DC Drive systems as well as various Process Control applications.

Modules are available which accept DC Voltage, DC Current, RTD & Potentiometer signals from field devices. The input signal is filtered, amplified (if necessary), isolated, & converted into the required output form (0-10V, 0-20mA, 4-20mA, +/-20mA) with minimal internal delay and without loss of accuracy.

Single input & Multiple isolated outputs are also offered to aid the system engineering needs for connecting the same input signal to separate devices such as Process Controller & Recorder without compromising safety and accuracy of measurement. A unique design feature of the modules allows the facility of system expansion using Back-plane connectivity to provide up to 8 nos. of Isolated Outputs for a single input signal.

The 24VDC Power Supply can also be fed from Back-plane to minimize wiring when multiple converters are mounted on DIN rail. This feature is extremely useful as it allows Hot Plug-In/Removal of a single module on the rail, without disturbing the plant operation to facilitate maintenance operation in a running plant in case of fault occurrence.

The SIM μ 3.0 modules are offered in the versatile ME type housings, which are internationally accepted and aesthetically pleasing DIN Rail mounted enclosures. The compact size (Single Output: 22.5mm width & Dual/Triple Output: 45mm width) allows high packing density of signal conditioners in limited panel space. Eco-friendly energy efficient design greatly reduces total power consumption and thus reduces the combined heat generated in the enclosed panel spaces.

The SIM μ 3.0 Analog Signal Conditioning & Isolation Module designs comply with the requirement of CE standards.
