1.1 Unit Functions and How They Work

1.1.1 Functions of Cassettes

 Using these cassettes attached to the CPU unit enables analog I/O control.
• An analog input and analog output can be controlled by attaching these extension cassettes
to the CPU unit.
• It is selectable from three types of cassettes in accordance with the intended use.
 Input and output with simple programs
• For input data, a digital conversion value (0 to 4000) is read as an input device (WX).
• For output data, a digital value (0 to 4000) is converted to analog output data by being
written into an output device (WY).
 The input and output range is switchable.
• The range can be switched with the switches on each cassette. The current input is switched
according to wirings.
 Equipped with the thermocouple disconnection alarm function (Thermocouple input
cassette)
• When a thermocouple is disconnected, the value is digitally converted to the fixed value
(K8000) so that you can determine the situation is not normal.
