Description
Line Drivers are available for the
HEDS-55XX/56XX series and the
HEDS-9000/9100/9200/9040/
9140 series encoders. The line
driver offers enhanced perform-
ance when the encoder is used in
noisy environments, or when it is
required to drive long distances.
The 70
°
C version utilizes an
industry standard line driver IC
(26LS31) which provides comple-
mentary outputs for each encoder
channel. The 100
°
C version
utilizes an industry standard line
driver IC, 26C31, which provides
complementary outputs for each
encoder channel. Thus, the
output of the line driver encoder
is A, A, B, B and I/I for three
channel versions. Suggested line
receivers are 26LS32 and
26LS33.
