FAQ

What is the maximum current load the TC-OAH061 can drive?

Up to 20 mA per channel into 500 Ω resistive loads; higher loads require alternate terminations.

Does the module provide isolation between channels?

Yes, all 6 channels are galvanically isolated to prevent cross-talk.

How fast does the module respond to output changes?

Output settling time is less than 2 ms to 95% final value with resistive loads.

Can it withstand RFI in industrial environments?

Yes, error is <2% across 27–1000 MHz at 10 V/m interference.

Is overcurrent or short-circuit protection included?

Yes, electronically current-limited to 21 mA maximum for safety.
