800 Series Discrete I/O Characteristics

The AS-B984-100 uses a true-high discrete signal scheme for its 16 inputs and 8 outputs. The specified input response time is 100 microsec maximum without filtering, while output response time is 1 msec maximum. Input switching behavior is defined by an 18 VDC ON condition threshold, a 19.2 VDC ON level under the specified source impedance condition, and a 6 VDC OFF level.

The module operates from 20-28 VDC and specifies a minimum 6 mA input wetting current at 24 VDC. The listed source resistance is 1000 Ohm, with a minimum output load current of 100 mA.

Field Installation Guidelines

Install the AS-B984-100 using the designated AS-8533-004 connector. Verify the 20-28 VDC supply range before energizing the circuit. Maintain correct polarity and confirm that connected field devices meet the stated ON and OFF voltage thresholds.

Route discrete signal wiring separately from high-current or high-noise conductors where practical. Apply the control cabinet grounding and shielding practices specified by the system installation documentation. Verify input source impedance and output load requirements against the module specifications before commissioning.

Do not apply operating conditions outside the documented electrical limits. Confirm all terminal assignments and field wiring with the applicable Schneider Electric 800 Series documentation before power-up.
