BBGBBG-Relay

Stackable Eight Channel Multiplexor
Description
The BBG-RELAY Eight Channel
Multiplexor provides multiplexing
capability of six analog or digital
inputs or outputs. These 4 inch x 5inch modules provide an eight-to-one
or one-to-eight multiplex or connect
together to provide a sixteen-to-two
or two-to-sixteen multiplex.
Multiplexing is controlled by one
digital switch or parallel port.
Applications include analog anddigital multiplexing in switching
networks or data acquisition
systems.

INPUTS/OUTPUTS
Inputs and outputs are available on 26 pin and 50 pin IDC
connectors. Each input/output channel contains six (6)signal lines that can be used for digital or analog data.
The BBG-RELAY can be stacked together to provide sixteen(16) channels of six (6) digital or analog data signals oreight (8) channels of twelve (12) digital or analogsignals.

CHANNEL SELECTION
Channels are selected using inputs D7 - D0 on connector J2or J3. Channel selection uses a standard Binary Coded
Decimal (BCD) format
as follows:
