It has a 120 Volts AC supply voltage and it has an operating voltage range of 74 to 132 Volts AC. It comes with an isolation voltage of 50 Volts which is continuous. It has an output voltage range of 74 to 132 Volts AC. It does not have any enclosure. It has a factory set operating temperature in the range of 0 to 60 degrees Celsius. The 1756-OA8D comes with a backplane rating of 175 mA at 5.1 Volts DC and 250 mA at 24 Volts DC. The maximum storage temperature is 85 degrees Celsius.
The 1756-OA8D provides ON/OFF detection and actuation. It comes with different diagnostic functions to detect short trips, no load conditions, and output levels, and to conduct pulse tests. It also comes with a field power loss alert and timestamping for diagnostics. On the front of the device, it has a display panel which shows information about the device. It shows the output information, fault and communication status, and the health of the module. It also has two removable terminal block housings which are the 1756-TBNH and the 1756-TBSH. The 1756-OA8D supports both isolated and non-isolated module types. It timestamps the sequence of events in the applications. It can support a variety of voltages. It has an on-board data alarm feature that alerts for various system events. It can also support configurable limit switching modules. It is digitally calibrated at the manufacturing plant, so no onsite calibration is required. It has an Ethernet port for communication purposes.
