Key Features
8 analog inputs for voltage and current signals.
Rated ranges include 1 V to 5 V, -10 V to +10 V, -5 V to +5 V, 0 to 20 mA, -20 mA to +20 mA, and 4 mA to 20 mA.
Resolution with overrange is max. 16 bit; parameterizable integration time is 10/ 16.67/ 20/ 100 ms.
Analog inputs are isolated from the backplane bus and isolated between channels in groups of 2; diagnostic and limit value alarms are parameterizable.
The module requires a 40-pin front connector and measures 40 mm wide, 125 mm high, and 117 mm deep.
This product is a spare part and has product cancellation status.
