NOTE: Main Board A I/O, INT1, INT5,
and INT6 I/O interface boards have
direct coupled contact inputs. Main
Board B I/O, INT2, INT4, INT7, and
INT8 I/O interface boards have
optoisolated contact inputs. SEL-421-0
and SEL-421-1 do not support Main
Board B I/O, INT2, INT7, and INT8 I/O
interface boards. SEL-421-2 and
SEL-421-3 support all the boards.
