Key Features
8 isolated analog inputs support voltage and current signals.
Voltage ranges include 1 V to 5 V, -10 V to +10 V, and -5 V to +5 V; current ranges include 0 to 20 mA, -20 mA to +20 mA, and 4 mA to 20 mA.
Maximum resolution with overrange is 16 bit including sign. Basic conversion time is 10 ms in 4-channel mode and 95/83/72/23 ms in 8-channel mode.
Rated load voltage is 24 V DC, with reverse polarity protection. The required front connector is 40-pin.
The module has potential separation between channels, between channels and the backplane bus, and between channels and the electronics power supply. Diagnostics and parameterizable diagnostic, limit value, and hardware interrupts are supported.
