2.3.7
Termination Panel
The NGC8206 termination panel acts as a connection to the outside world (see
). It features transient protection, a voltage regulator for digital
controller, positive temperature co-efficient fuses (PTC) and many other
safeguards to protect the remainder of the system from electrical damage. All
outside communications and I/O are channeled through this board. It is designed
to be a low cost, field-replaceable maintenance solution and is designed to
operate on either 12 VDC or 24 VDC.
