EPS100 Digital/Analog Remote Interface.
The digital and analog interface is a 15-pin, D-style subminiature female
connector,
located on the rear panel. The remote high-voltage go on, analog setpoint,
clamp
is up, clamp is down, and alarm outputs are contained in this connector.

Analog I/O (pins 2 and 6) is configured for 0-5 VDC single-ended operation.
Consult
the factory for applications that require a 0-10 VDC or bipolar interface.
Pins 5 and 7 are not tied together internally. All digital I/O should be
referenced
to pin 7 and all analog I/O should be referenced to pin 5. An external
common
connection between pins 5 and 7 will not alter the performance of the
EPS100
Pins 1 and 3 are optically isolated from DC power and DC common. A simple
remote
control interface can be accomplished by connecting pins 3 and 4 together
and
connecting pin 1 to DC common, via a switch, to set the high voltage go on
active
via the digital interface. |
