Auxiliary I/O Module

Triggering with the Auxiliary I/O Module is very straightforward and is
easy to set up. See Page 11 for accessory information.
7.5.1 Auxiliary I/O Module Description
The Auxiliary I/O Module has three contact outputs and four event inputs.
One of the output contacts is a solid state set (KYZ-rated) and the other
two are standard Form C mechanical contacts. The Event Inputs are
separated into three groups: one set rated at between 24 to 240 Vdc, one
set rated at TTL-level voltages (5 Vdc), and two sets are contact closure.
Signals are connected to the module with ring terminals and connection
to the Model 933A is by a nine-foot cable assembly.
The Auxiliary I/O Module is powered from the Model 933A and must be
installed with the Model 933A powered OFF.
