2.2 ADAM-5017 8-channel analog input module
The ADAM-5017 is a 16-bit, 8-channel analog differential input module
that provides programmable input ranges on all channels. It accepts
millivolt inputs (±150mV, ±500mV), voltage inputs (±1V, ±5V and ±10V) and
current input (±20 mA, requires 125 ohms resistor). The module provides
data to the host computer in engineering units (mV, V or mA). This module
is an extremely cost-effective solution for industrial measurement and
monitoring applications. Its opto-isolated inputs provide 3,000 V
DC
of
isolation between the analog input and the module, protecting the module and
peripherals from damage due to high input line volt- age. Additionally, the
module uses analog multiplexers with active over- voltage protection. The
active protection circuitry assures that signal fidelity is maintained even
under fault conditions that would destroy other multiplexers. This module
can withstand an input voltage surge of 70 Vp-p with ±15 V supplies.
