Notes

• *1 20 mA maximum for the expansion unit.
• *2 Use the FS-V21RM in FINE or TURBO mode when transmitting signals with a monitor.
• *3 If more than one unit is used, the ambient temperature will vary. Mount the units on the DIN rail with mounting hardware and verify that the output current is less than 20mA. 1 or 2 units: -10 to +55°C 14 to 131°F, 3 to 10 units: -10 to +50°C 14 to 122°F, 11 to 16 units: -10 to +45°C 14 to 113°F
• *4 When HIGH RESOLUTION is selected, S-APC is set to ON. When HIGH SPEED is selected, S-APC is set to ON for type R, and for any type other than R, S-APC is set to OFF. For others, the factory setting is S-APC OFF. The value in parentheses is the current consumption when using a 24 VCA supply voltage.
• *5 If two or more units are used, the ambient temperature will vary according to the following conditions. Mount the units on the DIN profile with mounting hardware and verify that the output current is 20 mA or less. 1 to 2 units: -10 to +55°C 14 to 131°F, 3 to 10 units: -10 to +50°C 14 to 122°F, 11 to 16 units: -10 to +45°C 14 to 113°F
