The Model 1088A/B can be fitted with dry contacts by installing an internal option board in
option Slot B. Using Option 19, the 1088B can have one set of Form C mechanical contacts. With
Option 29, the 1088B can have two solid-state contacts that can also 25 or +50 Vdc. For
additional information on these two options, see Section C.15, for Option 29, see Section C.20.
2.3.6 Standard Inputs/Outputs
The Model 1088B has four BNC connectors used for configurable inputs and outputs, the functions
of which are based on setting internal jumpers. The factory sets these jumpers at the time of
purchase, and they may be changed at any time as required. As outputs, all connectors may be
set to one of twenty-two different signals, and as inputs, two may be set as an event inputs, one
as auxiliary input and one set to function as an external timing reference. The connector labels
reflect the original setting from the factory.
