Specification
4.5 Digital Outputs Transistor
The transistor outputs are designed for higher switching frequencies than relay
contacts. Industrial high-side switches are used for sourcing current, sinking
current is not possible.
If the current for your application is too low, you can connect more than one
channels in parallel. The total current is equal to the sum of the single channels.
A maximum of 4 channels can be connected in parallel.
