Features:
- Sixteen differential inputs: one single-wide module concentrates industrial analog channels
- Flexible signal handling: documented voltage and current ranges require no external current resistor
- Fast complete updates: all channels refresh in 5.9 ms unfiltered or 8.2 ms filtered
901B-2555-A corresponds to CTI 2555-A analog-input hardware and is supported by the user-supplied product photographs showing the exact board identifier.
Its model-specific value is the combination of 16 differential channels, isolated backplane interface, configurable ranges, and complete-module conversion timing.
Engineering acceptance should link the physical board, field connector, range selection, channel scaling, filter choice, base slot, and known-signal test results.
Apter Power can review 901B-2555-A board images, connector, signal ranges, base, wiring, and condition before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Voltage inputs: select the documented unipolar or bipolar range for each measurement group.
- Current inputs: use the supported 0–20 mA path without adding an external current resistor.
- Scaling alignment: match controller engineering units to the selected electrical range.
- Unfiltered update: all channels refresh in the documented 5.9 ms cycle.
- Filtered update: the filtering option changes the complete update time to 8.2 ms.
- Resolution choice: interpret unipolar and bipolar counts with their documented conversion formats.
- I/O platform: confirm CTI 2500 Series or documented SIMATIC 505 base compatibility.
- Field connector: preserve the 2500-40F termination and validated channel map.
- Power budget: include the module’s 5 W backplane demand in the installed base calculation.
- Process analog acquisition: collect multiple voltage or current signals into a CTI 2500 station.
- SIMATIC 505 maintenance: service a documented compatible I/O base while preserving field scaling.
- High-density retrofit: replace a verified 16-channel board after range, connector, and project checks.
