4.11 9001 Discrete Telemetry Adapter
The 9001 adapter provides an inexpensive telemetry interface for 16 discrete elements.
It is used in conjunction with an application such as VTELRMT implementing a virtual
E2A remote; or with the ONSITE application for general purpose telemetry. The
applications are instances on a 6xxx embedded network processor.
The 9001 appears as follows:
The 9001 provides the following features:
Each SCAN point is optically isolated from the xxxx to which it is attached.
Each SCAN point is optically isolated from the 9001.
Each SCAN point is optically isolated from all other SCAN points.
The 9001 does not require external power for operation.
The 9001 minimizes and simplifies telemetry wiring.
The 9001 does not require any rack space and each supports 16 isolated scan points.
The 9001 reports the rack ambient temperature.
The 9001 may be attached to the 9480 or any 4xxx serial port.
The 9001 is the lowest cost telemetry solution.
