Power Connection Diagram
The diagram below shows the connections for powering the device. Note that a chassis ground braid must be connected between the stud on the back of the device and an Earth/chassis grounding point to provide EMI and ESD protection. The braid used during MIL-STD 461 EMI testing can be ordered using Fairmount Automation Part Number: 30110-015.
Warning: An improperly grounded case could result in electrical shock or incorrect operation of the controller.
Fuses
Each FAC-2100 has a fuse located in the rear of the device on the connector panel. Refer to the Parts List section for the fuse specification and ordering information.
Auxiliary Output Power
The FAC-2100 contains a 28V isolated (from the DC input power source) output source available to power sensors, actuators, etc. Most circular connectors on the back of the FAC-2100 contain pins that provide access to this source.
Note that the design of the Auxiliary Output Power source allows for multiple FAC-2100s to short together (no steering diodes are required) their power sources to provide a redundant source. As an example, this feature can be useful when multiple controllers are reading the same powered sensor – by connecting the Auxiliary Output Power from all controllers to the sensor it ensures that all controllers will be able to read the sensor if any or all others are offline.
