■ Terminal expansion board EB1<br />
The number of digital and analog<br />
inputs and outputs can be<br />
expanded with terminal expansion<br />
board EB1 (Expansion-<br />
Board 1).<br />
On terminal expansion board<br />
EB1, there are:<br />
3 digital inputs<br />
4 bidirectional digital inputs/<br />
outputs<br />
1 analog input with differential<br />
signal, for use as current or<br />
voltage input<br />
2 analog inputs (single ended),<br />
that can also be used as<br />
digital inputs<br />
2 analog outputs<br />
1 input for the external<br />
24 V supply for the digital<br />
outputs.<br />
Terminal expansion board EB1<br />
is installed in a slot in the electronics<br />
box.<br />
Boards LBA and ADB must be<br />
moved to allow installation.<br />
