Description
ELAU MAX‑4‑11‑03‑128‑08‑0‑0‑00
Technical Specifications: Control supply voltage 24 VDC, 128 channels digital input, 8 channels digital output, input compatible with sinking and sourcing 24 VDC signal mode, each output channel rated continuous current 0.5 A, SERCOS III fiber optic bus interface, IP20 protection rating, operating ambient temperature range 0 °C to +55 °C, per channel short circuit protection, module dimension 190 mm × 95 mm × 40 mm, net weight 0.42 kg.
Functional Features: High density multi‑channel digital signal processing, I/O data synchronizes with SERCOS real time bus cycle, independent short circuit and open circuit diagnostic function, LED status indicator for each group of channels, supports hot swap operation in PacDrive rack, bulk channel fault information upload to upper motion controller.
Application Scenarios: Complex packaging machinery multi‑point sensor acquisition, large automated assembly line actuator control, web converting production equipment field signal processing, textile full line automation signal collection, large scale multi axis production line remote I/O expansion.
Performance Parameters: I/O sampling cycle synchronizes with SERCOS bus at 125 µs, short circuit protection response time less than 5 ms, maximum stored fault records 800, performance derating activates when cabinet internal temperature exceeds 45 °C.
Material Composition: Metal reinforced rack mount housing, multi layer high density industrial printed circuit board, opto‑electronic isolation chips for signal channels, gold plated backplane contact pins, flame retardant plastic wiring terminal blocks.
Structural Characteristics: Horizontal plug‑in PacDrive rack module structure, front panel grouped LED indicator array, front mounted field wiring terminals, power supply and bus data transmitted through rack backplane, internal opto‑electronic isolation barrier between field signal and bus logic circuit.
Working Principle: Mass field 24 VDC input signals pass opto‑electronic isolation and get sampled by module logic unit. PacDrive motion controller sends output commands via SERCOS III bus. Module drives external solenoid valves and actuators after isolation processing. Module continuously monitors channel working status and fault events and transmits diagnostic data back to motion controller.
Installation Requirements: Insert module into assigned slot in PacDrive rack and lock front latches completely; connect stable 24 VDC control power supply; adopt shielded cables for all field signal wiring; maintain adequate ventilation space around module in control cabinet; separate low voltage signal wiring and high power motor cable routing paths.
Usage Notes: Do not remove module while system remains powered; separate control power and field actuator power supply circuits; never exceed single channel rated output current; keep conductive dust and corrosive gas out of control cabinet; regularly check terminal screw tightness under high vibration working environment.
