Communication
The C440 is provided with two levels of communication capability.
Basic Communication via
Expansion Module—
Monitoring Only
Basic communication on
the C440 is accomplished
using an expansion module.
The expansion module plugs
into the expansion bay on
the C440 overload relay,
enabling communications
with the overload via their
Modbus RTU (RS-485)
network. No additional parts
are required. See
figure below.
Safety Cover
Clear Lexan cover that mounts on top of the FLA dial and DIP switches when closed. ZEB-XSC
Reset Bar
Assembles to the top of the overload to provide a larger target area for door
mounted reset operators.

Advanced Communication—
Monitoring and Control
C440 also has the ability to
communicate on industrial
protocols such as DeviceNet,
PROFIBUS, Modbus RTU and
Modbus TCP, and Ethernet
(planned) while providing
control capability using I/O.
An expansion module
(mentioned earlier) combined
with a communication
adapter and a communication
module allows easy
integration onto the
customer’s network. See
figure below.

The communication adapter
comes standard with four
inputs and two outputs
(24 Vdc or 120 Vac) while
providing the customer with
flexible mounting options
(DIN rail or panel). See
