Description of the Technology

Signal Conditioning Modules (SCM) are used for interfacing different sub systems to data acquisition & control system providing
optical isolation. It also reduces EMI Interferences i.e. provides minimal emission & better immunity from conductive or radiative
coupling.  SCMs having generic specification to match various similar application.  

These SCMs are compatible with POF (Plastic Optic Fiber)/HCS (Hard core silica) cable. Input & output interface are from front
however these modules gets biasing voltage from backplane of Modules. It is tested up to 75meter length of POF cable. It includes
three types of SCMs:
Fast Analog Tx-Rx Module (FA)
Normal Analog Tx-Rx Module (NA)
Digital Tx-Rx Module (DTR)

Selection of voltage level of TTL/24V for Input & output signals is available for DTR module with inverting & non-inverting configuration.
FA and NA modules input and output voltage level is 0-10V. All modules are interchangeable with respect to position.

These SCMs are CE certified against EMC directive (IEC 61000-6-2, IEC 61000-6-4, IEC 61000-4-16 & IEC 61000-4-18), LV
directive (IEC 62368-1:2018), RoHS directive and Environmental standards. Functional testing of all SCMs are completed at ICRH,
ITER-India, IPR lab and ready to interface with experiment facility.

APPLICATIONS


It can be used to interface between sub systems with high probability of EMI interference like, High Voltage Power Supply, High Power
RF amplifiers, Gyrotron Systems, Klystron Systems, Electron Beam Systems, Particle accelerator Systems etc.
