I/O Connections
C.1 Introduction
A 25 pin D-sub connector, located on the rear of the SQC-310, provides
Input/Output connections.
Inputs can be activated either by connecting to a switch and shorting to Ground, or
they can be driven by a TTL compatible signal.
CAUTION
These are not isolated inputs! The voltage level applied
must be limited to between 0 and +5 volts with respect to
Ground.
WARNING
Output relays are rated for 30 V
rms
or 30 V (dc), at 2 A
maximum. Proper fusing, and adequate wiring insulation
and separation, should be provided to assure these limits
are not exceeded.
The pin assignments for the rear panel mounted I/O connector are shown
in
