24 V DC/AC POWER SUPPLY (/P1)
• Rated power supply: 24 V DC/24 V AC (50/60
Hz)
• Allowable power supply voltage range: 21.6 to
26.4 V DC/AC
• Insulation resistance: 20 MΩ or greater at 500 V
DC between power terminal and earth
• Withstand voltage: 500 V AC at 50/60 Hz for one
minute between power terminal and earth
• Rated power supply frequency (for AC): 50/60 Hz
• Alowwable power supply frequency (for AC): 50
Hz ± 2%, 60 Hz ± 2 %
• Influence of power supply voltage variation:
Variations of the measured value must be within
±1 digit in the range from 21.6 to 26.4 VAC/VDC.
• Influence of power supply frequency variation
(for AC): Variations of the measured value must
be within ±(0.1% of rdg + 1 digit) at a rated
frequency of ±2 Hz.
