SM-ADC1

PEP ARAB’s SM-ADC1 is a high-resolution and optoisolated A/D converter module that supports current or voltage inputs.
The six differential inputs offer high distortion immunity that is important for industrial environments.
An on-board EEPROM stores unique calibration and gain/offset data required by the signal converter.

► 6 differential & optoisolated inputs
► ±10V DC or 0..20mA input range
► 12-bit ADC with 1-bit non-linearity
► 50µs conversion time
► Overvoltage protection
► 2 user configurable LEDs
