SIM- Micro Series : The SIM Micro - Series comprises of a versatile range of single, dual / multichannel signal conditioning & isolation modules. A variety of modules are available which accept analog DC Voltage, AC Voltage, DC Current, AC Current and Frequency signal inputs from field devices, Drive systems & Control equipments. These modules are thus suitable for use in process control & instrumentation panels where a large number of signal modules are required and space is limited. For e.g. 16 signal modules can be stacked on a 450 mm rail length.

    
 
     
  SIM -Micro - 2.0 Series Variants:  
     
  Variants in this series are divided into following types each with 3 port isolation versions and single types:  
 
DC Voltage Signal Isolator
DC Current Signal Isolator
RTD Signal Isolator / Transmitter
Thermocouple Signal Isolator
 
     
 

The Micro - Series range comprises of compact Signal modules. The signal modules are available in single channel types. A variety of input modules are available which accept analog DC Voltage, DC Current, RTD, Thermocouple signals from field sensors or transmitters. The input signal is filtered, isolated, converted, amplified outputs. Thus enabling field devised to interface directly with indicators, controllers, recorders, DCS and PLC systems used extensively in manufacturing and process industries. This eliminates faulty reading in process measurement and control equipment caused by ground loops, noise due to inductive load switching, and other unpredictable electrical disturbances.

Various inoput/output combinations are possible besides the standard types given in this data sheet. The units operate on a wide auxiliary power supply span of 18 -36 V DC. An LED on the module front facia indicates the status of the power supply. It shall glow if the Power supply is health. Standard units are available in compact 35mm DIN rail mounted enclosures.
