Derating information for total current of outputs
If the digital outputs of the TM PosInput 1 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)
