2.7 Field I/O Connector
A field I/O interface connector provides a mating interface between the AP
modules and the carrier board. The 100 pin ST5-50-1.50-L-D-P-TR Samtec
connector is used on the AcroPack card as board to board interconnect.
This connector will mate with the 100 pin SS5-50-3.00-L-D-K-TR Samtec
connector on the carrier. The stack height is 4.5mm.
Threaded metric M2.5 screws and spacers are supplied with the module to
provide additional stability for harsh environments.
Pin assignments are unique to each AP model. Table 2.1 lists signal pin
assignments for the module field I/O connector. Every other pin of the 100
pin connector is left unconnected in order to meet the minimum distance
required for 60 Volt isolation.
