The AC output module includes certifications from the UL, CSA, cUL, and C-Tick standards. The module is designed for use with PLC controllers in various industries. The main purpose of the 1778-OAC input module is to convert the PLC signal into a signal that can be read and processed in the central control unit. The PLC system supports multiple controllers in a single chassis and multiple controllers operating through the same network. This powerful and cost-effective system has built-in communication ports for communication across different networks, interface modules, and serial ports.

The 1778-OAC output module operates on AC input with an input voltage of 120 Volts. The unit features ISA-style connectors and it has special ejector handles specifically designed for AC input/output operations. This component weighs around 2 kilograms or 4.6 pounds and it includes the following dimensions (W x H x D): 430 x 381 127 millimeters (17 x 15 x 5 inches). In regard to environmental specifications, the 1778-OAC module has an operating temperature range of 0 to 60 degrees Celsius or 32 to 140 degrees Fahrenheit, and a storage temperature range of -40 to 85 degrees Celsius or -40 to 185 degrees Fahrenheit. The relative humidity of the location where the unit is installed should be 5 to 95% (non-condensing). The unit tolerates a vibration of 1 G at 5 to 2000 Hertz and a shock of 30 G for 11 milliseconds.
