G4PB16J AND K RACKS WITH INTEGRAL INPUTS
G4PB16J and K Racks with Integral Inputs
Description
The G4PB16J and G4PB16K DC input racks provide 16 channels of
optically-isolated inputs for sensing on/off DC voltage levels by a B1,
B5, or B100 brain board, or any ISA bus-compatible computer with an
Opto 22 G4AC5 adapter card. Their compact size and design yields a
substantial space and cost savings over other 16-channel I/O boards.
All input channels are identical on each board and are ideal for
applications that need to monitor several4-16 VDC signals (model
G4PB16J) or 16-28 VDC signal (model G4PB16K). On-board LED
indicators display each channel’s on/off status.
Typical applications for the integrated DC input racks include sensing
the presence or absence of voltage from sources such as BCD devices,
TTL level devices, thumbwheel switches, and barcode readers.
Control connections are easily made to a 50-pin header connector. Barrier strips with screw terminals provide the field and
rack power connections. The logic supply is fused with a 1A fuse.These racks can be used with the G4AC5 computer
interface if jumpers 1 and 2 are removed. (The figure above right shows the location of these two jumpers. See
more information.)
