SM-ADC1

SMART-Module

with 6 Differential Analog Inputs 

PEP’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
