MODEL M550
T
he M550 PLC is a reliable, full-
featured Programmable Logic
Controller. It is a “smart” unit
providing both programmability and
interchangeability through a plug-in memory
module. As an integrated component of a
Supervisory Control and Data Acquisition System
(SCADA), the M550 provides input and output
(I/O) monitoring and control with simultaneous
“distributed” (RTU to RTU) and “central” (CTU
to RTU) type control operations. Its universal
communications interface can provide robust
control and data transfer via radio, dedicated
line, phone line, and fiber optic communication
media. The M550 can also be ordered with an
Ethernet controller in place of the RS-232 on
COM2 (Model M550E).
