*1 20 mA at maximum for the expansion unit.
*2 Use the FS-V21RM in the FINE or TURBO mode when outputting signals with a monitor.
*3 If more than one unit is used together, the ambient temperature varies with the conditions below. Mount the units on the DIN rail with mounting brackets and check that the output current is 20 mA or less.
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 has been selected, S-APC ON is fixed. When HIGH SPEED has been selected, S-APC ON is fixed for the R type and for anything other than the R type, S-APC OFF is fixed. For others, the factory setting is S-APC OFF. The value inside the parentheses is the current consumption when using a 24 VAC power supply voltage
*5 To connect several units they must be mounted on a METAL DIN rail. Ensure that the output current is 20 mA max. With several units connected, the allowable ambient temperature range varies as follows: 1 to 2 units connected: -10 to +55 °C 14 to 131°F, 3 to 10 units connected: -10 to +50 °C 14 to 122°F, 11 to 16 units connected: -10 to +45 °C 14 to 113°F
