The common output of channel 48 is the single channel of the 96 x
I multiplexer, and the 48 HI and 48 LO connections make up the
96 channels. By closing the appropriate channel (0-
47) and
opening or closing channel 48, a 96 x I multiplexer is achieved.
Table 3-1, 1260-37 Multiplexer/Scanner Circuit Channel Closure
Channel interconnect for 1, 2 and 4-wire modes.
1-wire mode:
<channel> <channel> output <channel> input
(channel 48 open)
0 thru 47 always J202- 132 (see 2-wire mode channels 0-47
input pins b-side of channel)
(channel 48 closed)
0 thru 47 always J202- 132 (see 2-wire mode channels 0-47
input pins a-side of channel)
Thus, a one 1 x 96 1-wire mode is acheived.
2-wire mode:
<channel>
<channel> output pins
<channel> input pins
