Industrial AS-B-883-001 High Speed Counter Module

AS-B883-001 High Speed Counter Module (Modicon 984-series) provides two independent counters for high‑speed counting and timing tasks within Schneider Electric Modicon PLC systems. Counter 1 is bi-directional (up/down) and Counter 2 is unidirectional up; input modes include Pulse or Quadrature encoder, with internal clock options at 1 kHz and 1 MHz and a maximum counting rate of 50 kHz. The module supports up to 9,999,999 counts on Counter 1 and up to 9,999 on Counter 2, and offers 6 auxiliary inputs and 3 outputs for logic and signaling. It accepts multiple supply voltages—5 Vdc (2.4–5.5 V input thresholds), 12 Vdc (6–16 V), or 24 Vdc (12–32 V)—and provides up to 140 mA per output at 5 V, with total power draw of 677 mA on the +5 V rail (other rails 0 mA). The AS-B883-001 occupies a single PLC slot, weighs about 1.49 kg, and ships with a terminal connector; two programmable outputs are available along with three modes of operation and hardware/software reset and enable options.
