Interval Timer CPM1A PCs have a high-speed interval timer which can be set from 0.5 ms to
319,968 ms. The timer can be set to trigger a single interrupt (one-shot mode) or
repeat scheduled interrupts (scheduled interrupt mode).
High-speed Counter CPM1A PCs have a high-speed counter that can be used in incremental mode
or up/down mode. The high-speed counter can be combined with input inter-
rupts to perform target value control or zone comparison control that isn’t
affected by the PC’s cycle time.
Pulse Output Function The CPM1A transistor output models have an output function capable of output-
ting a pulse of 20 Hz to 2 kHz (single-phase output).
Analog Setting Function The CPM1A PCs have 2 analog volume controls that can be used to make
manual analog settings.
Up to 3 Analog I/O Units can be connected to provide analog inputs and outputs.
Each Unit provides 2 analog inputs and 1 analog output, so a maximum of 6 ana-
log inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O
Units.

can be used with the 1 to 5 VDC
and 4 to 20 mA settings.
Signal range: 0 to 10 V,
–10 to 10 V, or 4 to
20 mA,
Resolution of 1/256

to 5 V, –10 to 10 V, 0 to 20 mA, or 4
to 20 mA, Resolution of 1/6,000
The open-circuit detection function
can be used with the 1 to 5 VDC
and 4 to 20 mA settings.
Signal range: 0 to 10 V, 1
to 5 V, –10 to 10 V, 0 to
20 mA, or 4 to 20 mA,

A Temperature Sensor Unit can be connected to provide up to 6 inputs for tem-
perature input from sensors, such as thermocouples or platinum resistance
thermometers.
Temperature Sensor Unit Functions
Thermocouple input (CPM1A-TS001/002; 2/4 input points):
K: –200° to 1,300°C (–300° to 2,300°F)
0.0° to 500.0°C (0.0° to 900.0°F)
J: –100° to 850°C (–100° to 1,500°F)
0.0° to 400.0°C (0.0° to 750.0°F)
Platinum resistance thermometer input (CPM1A-TS101/102; 2/4 input points):
Pt100: –200.0° to 650.0°C (–300.0° to 1,200.0°F)
JPt100: –200.0° to 650.0°C (–300.0° to 1,200.0°F)
Host Link Communications The CPM1A PCs are compatible with the Host Link, which allows communica-
tions with personal computers. The CPM1A using the Host Link can also com-
municate with Programmable Terminal using host link commands.
An RS-232C Adapter is used for 1:1 communications and an RS-422 Adapter is
used for 1:N communications.
One-to-one PC Link A data link can be created with a data area in another CPM1A, CQM1, CPM1,
SRM1 or C200HS or C200HX/HG/HE PC. An RS-232C Adapter is used to make
the 1:1 connection.
NT Link Communications High-speed operations can be achieved by providing a direct access by con-
necting the CPM1A to the OMRON Programmable Terminal through the NT Link
Interface. An RS-232C Adapter is used for this connection.
Up to 3 CompoBus/S I/O Link Units can be connected to make the CPM1A a
Slave Device in a CompoBus/S Network. The I/O Link Unit has 8 input bits (inter-
nal) and 8 output bits (internal).
