7.5.2. Analog external inputs
Changing the voltage of the signals entered to "analog external inputs" enables you to set
either the operation temperature or the required operation performance.
If using this function, make the following DIP switch settings.
i) Set the "Analog external inputs ON/OFF" setting to "ON".
ii) Set the control item (either the operation temperature or required operation perfor-
mance).

● Select either of the following two power supply methods.
(Factory setting is Type-i)
Type-i
• Using a power supply from other than the DX-kit (Connected unit, etc.)
• Usable tolerance voltages and currents: AC 220 to 240 V /1A max or
DC 30 V max /1A Max
Type-ii
• Using a power supply from the DX-kit control unit
• Output voltage: Hi DC12V±2V, Lo 0 V / 50 mA max
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.

• Precautions for Type-i
If connecting a dielectric load such as a relay
coil, etc., to the connected device, make sure to
add a surge protector circuit to the load side as
shown in the diagram.
