MITS - 88-PCI
Process Control Interface Board
Probably reflecting upon the companies
early roots, it was the first company to offer an S-100 board for process
This board was for users wishing to
control the operations of almost any electrical or mechanical device with an
Altair 88-PCI board. Through the use of relays, opto-couplers and software, the
PCI board received process information and transmitted control signals. A
complete interrupt structure and handshake configuration was included, both were
Possible applications included monitor
environmental conditions (heat, light, humidity} in the home or laboratory;
control devices; control automatic sorting and grading of products on an
assembly line; read and respond to scientific test results, such as changes in
pressure, pH or viscosity etc.
Isolation: Resistance input to output: 200G ohms. Voltage: 15V min.
Input active current: 10-100ma.
Propagation delay: Varies with diode current from
input to data (D) line.
Diode and Transistor: Turn on: 6 u sec. Turn off: 10 u sec, typ.
Isolation: Contact to contact 750V AC at 250M ohms. Contact to coil frame: 2000V
Propagation delay: Pull in: 3.5 msec.
Release: 4 msec. Bounce: 1.2 msec.
I cannot locate a
manual for this useful looking board.
Here is a brochure. If you have one or a .pdf file and would
like to share it with others please let me know.
