FAQ

What happens if an output leg fails?

The module switches in <10 ms to maintain continuous TMR operation.

Can this module handle reverse voltage on loop power?

Yes, up to +42.5 VDC, protecting the output circuitry.

How do I select appropriate load resistance?

Choose according to output loop power table; higher loads need higher supply voltage.

Is the 3805E compatible with existing 8-point analog outputs?

Yes, designed to replace older Triconex AO modules with similar configurations.

What indicators should I monitor during commissioning?

Check PASS, FAULT, ACTIVE, LOAD, PWR1, PWR2 LEDs to ensure proper module operation.
