Derating information for total current of outputs
If the digital outputs of the TM Count 1x24V are operated with resistive or inductive loads,
you should derate the total current of the loads at the digital outputs of the technology
module. The total current is the sum of the load currents at all digital outputs of the module
(without encoder supply).
The following derating curve shows the load capacity of the digital outputs depending on the
ambient temperature and mounting position under the following conditions:
● Load resistance: 48 Ω (IEC 947-5-1)
