*1 With a load resistance of 250 Ω, this value is guaranteed by KEYENCE inspection facilities. Errors may occur due to your environment.
*2 You can increase the number of expansion units possible in the system by lowering the total analog output current below 750 mA. For details, contact your nearest KEYENCE office.
*3 When expanding the system by one or more FR-SA2 units with the FR-S01 connected or by eight or more FR-SA2 units with the FR-SH01 connected, use a power voltage of 21.6 V or higher.
*4 When expanding the system by four or more FR-SA0 units with the FR-S01 connected or by ten or more FR-SA0 units with the FR-SH01 connected, use a power voltage of 21.6 V or higher.
*5 When expanding the system by 1 expansion unit, ensure the ambient temperature is 50°C 122°F or less. When expanding the system by 2 or more expansion units, ensure the ambient temperature is 45°C 113°F or less.
*6 When expanding the system by six or more units with the FR-S01 connected or by eight or more units with the FR-SH01 connected, contact your nearest KEYENCE office.
*7 When expanding the system by 13 or more units with the FR-SH01 connected, contact your nearest KEYENCE office.
*8 When expanding the system by 1 expansion unit, ensure the ambient temperature is 50°C 122°F or less. When expanding the system by 2 or more expansion units, ensure the ambient temperature is 45°C 113°F or less.
