Note 1
Note 1: Terminal 9 is also the return for the 24 Vdc
whetting voltage on terminal 1, when
terminal 1 is paralleled to additional
applications (e.g., to whet opto-inputs
IN101 - IN106). Terminal 1 has a load limit
of 0.1 A and should be fused for
protection (Bussman GMD-0.125 fuse or
equivalent).
