• Pt1000s: 320 µA
Pt100/Pt1000 used curves: alfa = 0.00385
Digital Inputs:
• Logical levels:
Logical level “0”: from 0 to 0.8 Vdc
Logical level “1”: from 3 to 30 Vdc
• Maximum input voltage: 30 Vdc
• Input Current @ 30 Vdc (typical): 3 mA

Digital Outputs
• Maximum output voltage: 30 Vdc
• Maximum output current: 200 mA
Relays:
• Maximum Current: 3 A @ 250 Vac; 3 A @ 30 Vdc
Loggings:
• Can log up to 1000 channels per second. Limits: 1 channel at 1000 loggings per second or 100 channels at 10
loggings per second.
• Can log either in the internal flash memory
(2162688 bytes → approximately 512 k loggings) or in the SD card (*).
• Allows the option of circular logging, where, after filling up the memory, the oldest data will be overwritten by more
recent data.
• Allows data to be downloaded during logging.
(*) IMPORTANT: The effective logging rate depends heavily on the quality and speed of the SD card used. Always
prefer to use cards of well-known brands (SanDisk and Kingston, for example). If the wanted logging rate is high, prefer
to use Class IV or above cards.
Maximum number of channels that can be logged: 100
Supported file systems: FAT32 e FAT16, both in USB flash drives and SD cards
24 V output: 24 Vdc ± 20 % with a minimum load current of 4 mA. Maximum load current: 160 mA. This output is not
provided in the 24 V model!
