Data setting

8-bit binary with sign bit

Conversion time (See note 2.)

10 ms/Unit max.

Isolation method

Photocoupler isolation between I/O terminals and PC

(There is no isolation between the analog I/O signals.)

Note

1. The voltage output and current output can be used at the same time, but the total output current cannot exceed 21 mA.

2. The conversion time is the total time for 2 analog inputs and 1 analog output.

Temperature Sensor Units

By mounting a Temperature Sensor Unit (CPM1A-TS001/TS002/TS101/TS102) to the PC, input can be obtained from a thermocou-

ple or platinum resistance thermometer,and temperature measurements can be converted to binary data (4-digit hexadecimal) and

stored in the input area of the CPU Unit. For details on the maximum number of connectable Units, refer to 7.
