RL ≥ 10 kΩ (0 to 10 V) or RL ≤ 500 Ω (0 to 20 mA / 4 to 20 mA).
(*)
The number and/or type of analog/digital inputs/outputs may vary. Depending on the Plug-in module (accessory) used. For
the table above, it was considered the CFW500-CRS485 plug-in module. For further information, refer to the programming
manual and the guide supplied with the optional item or in the CD-ROM.
(**)
The maximum capacity of 150 mA must be considered adding the load of the 24-V power supply and transistor output, that
is, the sum of the consumption of both must not exceed 150 mA.
