Product More Technical Description
The 1756-OA8E is a digital AC output module. It is manufactured and created by Allen-Bradley. It belongs to the ControlLogix family. It has 120 Volts AC output. It has a maximum operating voltage of 132 Volts AC and a minimum operating voltage 74 Volts AC. It also comes with 8 electronically fused inputs. The 1756-OA8E has 2 removable terminal block houses. It has a backplane power rating of 7.02 watts. It has a maximum operating temperature of 60 degrees Celsius and a minimum temperature of 0 degrees Celsius. It has an open type enclosure. It needs a environment with 5 to 95% relative humidity for operation. The 1756-OA8E comes with different voltage interface capabilities. It also has point level output fault states. On the front of the module, there is a display which shows the output, fuse, communication status, and the health of the module.
The 1756-OA8E has time stamping ability to capture different series of events during the operation of the module. It has enhanced diagnostics to detect field and system failures. This module is easy to operate and to set up. It has components which are easy to replace in case maintenance is needed. It has on-board data alarming features. It also comes with one HART modem per channel for a faster HART data update. It is pre-calibrated so that no onsite calibration is needed.
