Introduction
The ACEpc baseboard is a platform for using Arcom processor boards together with AIM 104 I/O
modules.
ACEpc Baseboard key features are:
Field powered at 24VDC nominal
Terminal breakouts for up to 128 I/O lines
16bit and 8bit PC/104 bus support
RS232 COMMS ports with PC/AT compatible 9way connectors
188EB, 386EX, SBC104, Elan-104 processor boards.
Up to 8 PC104 I/O modules can be installed
Power Input
Power Input The standard power supply for ACEpc is 18watts fully isolated which is capable of
supporting up to 5 PC104 I/O modules.
Other options available are: -
15watts non-isolated (up to 4 PC104 I/O modules)
30 watts isolated
(up to 8 PC104 O/I modules)
The input power can be within the range of 12VDC. To 30VDC.
Over voltage protection and reverse protection are by electronic resetable fuse with a shunt Zener
limiter.
On-board supply regulators offer 5VDC (logic) and ±12VDC for RS232 COMMS. Power is shared
between the logic supply and the COMMS supply up to the maximum. The maximum taken by
COMMS is 2.5W, which is sufficient for up to four Arcom AIM104-SER4C serial boards (giving 16
RS232 PORTS).
Non-isolated power supplies are referenced to the field power supply although the OV common is
separate from the chassis ground. APCpc Baseboard includes the facility for a Ground strap to OV if
this is required for safety or shielding. (See diagram). To connect GND to the system, either use the
stud on the case, or wire to the Power Input GND terminal. Use a wire link between the on-board
screw terminals OV and GND to guard against floating OV.
