Model Interpretation

B883 = Intelligent Special I/O Module Series; 1XX = Absolute Value Gray Code Cam Model; 111 = 12-bit Parallel Absolute Value Input + Speed Compensation Cam Control Specification. Compared to 101 which has no speed compensation, 111 is suitable for dynamic correction cam output timing when adapting to variable-speed spindle. Technical Specifications

Encoder acquisition: 12-bit parallel binary / Gray code absolute encoder, 24VDC level signal, with latch control bit provided

Discrete points: 12 channels 24VDC open-collector DI (encoder latch, enable, cam group switching); 8 channels 24VDC sink-type transistor DO

DO electrical: Single point rated 200mA, on-state voltage drop ≤ 0.6V, short-term withstand voltage peak 32VDC, off-state leakage current ≤ 0.75mA @ 28.8Vdc

Backplane power consumption: 5VDC @ 1000mA, standard single-slot chassis occupancy

Response performance: Maximum cam output response 20ms, built-in speed measurement calculation to achieve dynamic advance / delay output compensation for variable speed

Dimensions: 51 (W) × 203 (H) × 280 (D) mm, net weight 0.66kg

Environmental parameters: Operating 0~60℃, storage - 40~85℃, humidity < 80% RH without condensation, IP20 indoor protection

Interface and matching base

Universal terminal block base AS-8535-000, compatible with B882 full series, B883-001/002/101 base.

Core functions

12-bit absolute value real-time acquisition of spindle physical position, embedded multiple groups of programmable cam data tables; unique speed compensation calculation, automatically correct cam switch trigger point during spindle speed increase/decrease, eliminating action lag error caused by variable speed; 12 channels DI for cam formula switching, encoder hardware latch, equipment start/stop interlock; 8 channels DO for automatic on-off according to axis position instead of mechanical cam; panel position operation, fault alarm indicator lights, full parameter PLC software configuration without hardware dip switch. Applicable scenarios

High-speed rotary printing machine, rubber vulcanization forming equipment, continuous stamping machine, multi-position indexing turntable, chemical fiber drawing machine variable speed spindle cam control.

Operation and Maintenance

Insert the standard I/O slots of Modicon 800 rack directly; for variable speed conditions, priority check the encoder wiring shielding and 24V power supply; DO drives for solenoid valves must be equipped with rectifier diodes; the rack can be mixed with B875 analog modules and B882 counting / switch quantity modules.
