FAQ

Questions Buyers Ask Most

What input transducers are compatible with 3500/25-02-03-RU?＋

3500/25-02-03-RU accepts proximity-probe or magnetic-pickup inputs. Its 03 option uses Internal Barrier I/O with internal terminations, so the transducer, field wiring, and barrier configuration must match the rack design.

Which monitoring applications use 3500/25-02-03-RU?＋

3500/25-02-03-RU converts shaft event signals into digital Keyphasor timing references for rotational speed, 1X vibration amplitude, phase, and tracking-filter measurements by monitor modules in a 3500 rack.

How should 3500/25-02-03-RU be installed in a 3500 rack?＋

3500/25-02-03-RU uses two half-height 2-channel cards; each card occupies one half-height front slot, while its Internal Barrier I/O module occupies one full-height rear slot. Follow the applicable internal-barrier installation requirements.

What should be checked when commissioning 3500/25-02-03-RU?＋

When commissioning 3500/25-02-03-RU, verify transducer type, signal amplitude and threshold settings, the 1 to 1,200,000 cpm input range, channel status, and the front and rear buffered Keyphasor outputs.

What ordering data does 3500/25-02-03-RU define?＋

In 3500/25-02-03-RU, 02 orders two half-height 2-channel cards, 03 orders Internal Barrier I/O with internal terminations, and RU selects the available country-specific approval option. Confirm the end-user location and site approval requirements before ordering.
