PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1794-OE4 is an analog output module from the FLEX I/O series. This unit provides four non-isolated single-ended outputs for automation systems. It accommodates selectable output current ranges of 0 to 20 mA or 4 to 20 mA. The module also supports output voltage options spanning -10 to 10V and 0 to 10V.
Output data uses a 16-bit two's complement left-justified format. Digital to analog conversion operates via pulse width modulation. Voltage outputs supply a maximum current load of 3 mA. Current outputs handle resistive loads between 15 and 750 ohms at 24V DC. The module draws 20 mA of Flexbus backplane current during normal operation. It operates in ambient temperatures from 0 to 55 degrees Celsius.
