*1 The expansion unit of the FS-V20 Series cannot be connected to the main unit of the CZ-V20 Series. To connect the FS and CZ Series units, connect the expansion unit of the CZ-V20 Series to
the main unit of the FS-V20 Series.
To connect two or more expansion units, connect the CZ-V20 Series units on the right of the FS-V20 Series units.
*2 20 mA max. when several units are connected.
*3 When several units are connected, the acceptable ambient temperature varies depending on the conditions given below. To connect several units, be sure to mount them to a DIN rail and to limit the output current to a maximum of 20 mA.
When 1 or 2 units are connected: -10 to +50 °C 14 to 122 °F
When 3 units are connected: -10 to +45 °C 14 to 113 °F
