WebSNAP Isolated 2-Ch 0-250 V RMS AC/DC Analog Input Module. The SNAP-AIVRMS-i module provides two isolated channels with an input range of 0 to 250 volts AC or DC. The SNAP-AIVRMS-i module may be used to monitor 120/240-volt AC/DC and 12/24/48-volt AC/DC system voltage and is ideal for differential voltage measurements. WebJun 14, 2016 · make sure you know which way round your ohm-meter works you want + to pin 5 and - to pin 6 when activated you should read very low resistance when not - high resistance if you do get polarity wrong, the low resistance won't be quite so low - This just might be the problem – Defiler Jun 14, 2016 at 14:32

Accepting US, CAD, AU, NZ ($) & EU Orders (€) An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators … See more The value of optically coupling a solid state light emitter to a semiconductor detector for the purpose of electrical isolation was recognized in 1963 by Akmenkalns, et al. (US patent 3,417,249). Photoresistor-based … See more An opto-isolator contains a source (emitter) of light, almost always a near infrared light-emitting diode (LED), that converts electrical … See more Resistive opto-isolators The earliest opto-isolators, originally marketed as light cells, emerged in the 1960s.
