^1 This is the guaranteed value from verification performed at KEYENCE inspection facilities with a load resistance of 250 Ω. Measurement errors may occur depending on the customer’s environment. ^2 The number of expansion units can be increased by making the output current less than 750 mA in total. Contact your local KEYENCE representative for more details. ^3 Contact your local KEYENCE representative when adding more than the aforementioned number of units. When FR-S01 is connected: 6 units. When FR-SH01 is connected: 8 units. ^4 When expanding the FR-SA2 with the number of units indicated on the right or more, use a power voltage of 21.6 V or higher. When FR-S01 is connected: 1 unit; when FR-SH01 is connected: 8 units. ^5 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. ^6 If the number of expansion units is one, the ambient temperature must be 50°C or less, and if the number of expansion units is two or more, the ambient temperature must be 45°C or less.
