The Allen-Bradley 1794-OE4 is a versatile analog output module from the Flex IO family, designed to enhance distributed I/O systems by offering four configurable output channels that supply both current (0 to 20mA, 4 to 20mA) and voltage (+/-10VDC, 0 to 10VDC) signals, making it ideal for controlling devices like VFDs and modulating control valves. This module boasts a precise 12-bit resolution plus sign, employing pulse width modulation for output conversion, and ensures seamless integration with various communication adapters such as Ethernet, ControlNet, and Profibus, alongside compatibility with terminal bases like 1794-TB2 and others. Additionally, it features robust performance with a current accuracy of 0.425% and voltage accuracy of 0.133% at 25 °C, continuous isolation voltage of 50 volts, and requires no calibration, all housed in a compact unit measuring 94 x 94 x 53.3 mm, complete with status indicators for efficient monitoring.
