GENERAL DESCRIPTION
The Serial Digital Pneumatic Module converts
electronic signals to eight pneumatic signals. it
is packaged as a Eurocard module and fits into a
Eurocard rack with a 78145 series motherboard.
When configured in retrofit mode, it plugs into a
74847 motherboard. The module has an electri-
cal connector and a quick disconnect pneumatic
connector.
The Serial Digital Pneumatic Module may be com-
manded from any of three sources:
• Serial bus
• Discrete 24 VDC inputs (new or retrofit)
• Ransburg parallel (TTL) bus (for
retrofit applications).
On the module front panel, LED’s indicate when
each valve is energized. Also, the front panel
switches provide momentary manual override for
each valve. These front panel switches can be
locked-out with an on-module switch setting or by
a signal from the electrical connector.
