Allen Bradley manufactures the 1756-OA8E. It is a digital alternating current module. It belongs to the family of ControlLogix family. This module has 120 volts alternating current module. It operates at a voltage of 132 volts alternating current maximum and a minimum of 74 volts alternating current. It has 2 removable terminal blockhouses and 8 electronically fused inputs. It operates at a maximum temperature of 60 degrees Celsius and a minimum of zero degrees Celsius. 1756-OA8E has a backplane power rating of 7.02 Watts. This module comes with different voltage interface capabilities. For its operation purpose, the environment should between 5 to 95% relative humidity. The 1756-OA8E has enhanced diagnostics to detect field and system failure since it has the time-stamping ability to capture different series of events during its operation.1756-OA8E is easy to operate and set up also its components are easy to replace during maintenance. The fuse, health of the module, output, and communication status is displayed on the front of the module. This enhances the diagnostic and troubleshooting. This module comes with an on-board data alarming feature. It has one HART modem per channel for a faster HART data update. It does not require onsite calibration since it is normally pre-calibrated.. It meets various safety standards, thus suited for most major industrial applications. This module offers certification to a robust control system security standard. When using the 5580 controllers, up to 45% capacity is gained. This module has a 1 gigabyte embedded Ethernet port which enables high-speed communications. The motion control offers controller functions that maximize the system performance the extra security.
