ELC Programmable Logic Controllers
ELC Controllers / Modules
ELC Right Side Digital
Expansion Modules
Digital right side expansion modules
can be used with any ELC controller.
They simply snap together to allow the
ELC backplane to pass through each
connected module. Add only the
amount of I/O you need. Choose I/O
counts as small as 6 points and as
large as 16 points per module.
I/O modules are available in a broad
selection of AC/DC inputs, relay/transis-
tor and high current outputs which may
be used together in any combination.
Add as many modules as needed to
reach the proper I/O count. In addition
to the embedded I/O on the PB, PC, PA
and PH controllers, 112 digital inputs
and 112 digital outputs can be added
by use of expansion modules. An addi-
tional 240 digital inputs and 240 digital
outputs can be added to the PV con-
troller. These I/O counts are all inde-
pendent of the analog and specialty
module I/O counts.
