  • Manufacturing and OEM Applications


Rish CON SI-102 are compact isolating amplifiers designed to isolate inputs,outputs and power supplies, preventing interference from spurious potentials. The Rish SI-102 has two electrically insulated outputs, obtained from a single input signal. This prevents interference between voltage, current or signal level. Dual outputs also solve grounding issues of meshed signal networks. It’s small size make it ideal for applications where space is at a premium.
