The CQM1H’s rack-less modular design lets
you customize your control system by adding
“inner boards” for advanced functions, as well
as specialized I/O and communications
modules. CQM1H offers the most flexibility of
all PLC systems in its class.
4 different base CPUs to choose from; 16 DC inputs
built in; expands up to 512 points
No separate backplane required
Inner Boards allow “customized” configuration of the
Serial communications inner board supports protocol
macro feature for communication with third-party serial
Supports all existing and new CQM1 I/O and
specialized I/O modules
Optional memory cassettes allow backup of sensitive
data, provides a real-time clock
ControllerLink network transmits 8 kword data packets
at up to 2 Mbps; 32 nodes
Advanced instruction set includes PID, floating point
math, protocol macro instructions and more
CompoBus/S, SYSMAC BUS and AS-interface masters
support remote I/O
Up to 15.2 kwords of program memory
Select the CPU and I/O modules (discrete, analog and dedicated special function types) then determine the power supply based on the
current consumption. The I/O Control and Interface adapters give you the option of dividing the CPU and I/O system into two narrower
units than the examples shown below. The CQM1H-CPU51/CPU61 models offer space-saving position and motion control solutions as
well as additional analog and serial communications capabilities right at the CPU.
CQM1H modules are assembled with connectors on their sides.
256 or 512 I/O points max.
11 modules max. (16 modules max.
using I/O Expansion and Control In-
terface adapters). The total number
of words cannot exceed 16.
