From Contec Americas. 32 Opto‑Isolated Inputs 32 Open‑Collector Outputs 200µs Response Time 35V Max Output Voltage Contec Americas · USB I/O DIO‑3232LX‑USB 32‑Ch DI · 32‑Ch DO · Opto‑Isolated · 12‑24 VDC · USB Hub View Collection 01 32‑Channel Isolated Digital I/O The DIO‑3232LX‑USB provides 32 opto‑isolated inputs and 32 open‑collector outputs for USB‑based digital I/O. Supporting 12‑24 VDC signals, it is ideal for industrial automation and machine control. The isolated design (500Vrms) protects your PC from electrical noise and transients. Common terminals are provided per 16 channels for flexible power supply configuration. Input Features 32 opto‑isolated inputs 12 – 24 VDC Current sinking compatible 200 µsec response time Interrupt on all inputs Output Features 32 open‑collector outputs 35 VDC max, 100 mA/ch Low saturation transistor Surge voltage protection Overcurrent protection (8‑ch units) USB hub function – up to 4 DIO‑3232LX‑USB units can be connected to a single USB port using the built‑in hub. Connect additional CONTEC USB devices as well. (5VDC self‑power required when using hub function.) 02 Industrial‑Grade Reliability Engineered for demanding factory automation and control applications. The digital filter prevents false triggers from noise or contact bounce, and the interrupt capability on every input enables real‑time event handling. Outputs include surge and overcurrent protection for robust operation. Opto‑isolated I/O – 500Vrms isolation between USB (PC) and I/O interfaces for excellent noise immunity. Digital filter – Programmable filter on all inputs prevents false triggers from noise or chattering. Interrupt on all inputs – Each input can generate an interrupt on rising or falling edge. Enable/disable per bit. Surge and overcurrent protection – Zener diode for surge voltage; overcurrent protection circuit per 8 output channels. Common terminal per 16 channels – Supports different external power supplies for input and output banks. 03 Full Specifications Specification Detail Model DIO-3232LX-USB Input type Opto‑isolated (current sink compatible) Input channels 32 (common per 16 channels) Input resistance 4.7 kΩ Input ON current 2.0mA or more Input OFF current 0.16mA or less Interrupt All inputs, edge selectable Response time 200 µsec within Output type Opto‑isolated open‑collector (current sink) Output channels 32 (common per 16 channels) Output rated voltage 35 VDC (max) Output rated current 100 mA per channel (max) Residual voltage with output on 0.5V max (at 50mA), 1.0V max (at 100mA) Surge protector Zener diode Response time (output) 200 µsec within USB specification USB 2.0 / 1.1, Full‑speed / High‑speed Power supply Bus power or self‑power (5VDC) Allowable distance Approx. 50m (depending on environment) Dielectric strength 500 Vrms External circuit power supply 12‑24 VDC (±10%), separately required Current consumption 5VDC 500mA (max) Dimensions (mm) 205(W) × 140(D) × 44(H) Weight Approx. 500g Operating temperature 0 – 50°C Operating humidity 10 – 90%RH (no condensation) Standards VCCI Class A, CE (EMC Class A, RoHS), UKCA Included items Unit, USB cable (1.8m), cable attachment, clamps, power connector, ferrite core, manual Datasheet version As of September 2024 04 Optional Accessories Product Name Model Description Shielded cable with 96‑pin half‑pitch (both ends) PCB96PS-05P / -1.5P / -3P / -5P 0.5m / 1.5m / 3m / 5m Shielded cable with 96‑pin half‑pitch (one end) PCA96PS-05P / -1.5P / -3P / -5P 0.5m / 1.5m / 3m / 5m Flat cable with 96‑pin half‑pitch (both ends) PCB96P-1.5 / -3 1.5m / 3m Flat cable with 96‑pin half‑pitch (one end) PCA96P-1.5 / -3 1.5m / 3m Connection conversion shield cable (96P→37P×2) PCB96WS-1.5P / -3P 1.5m / 3m Screw terminal (M3×96) EPD-96A / EPD-96 Spring‑up / standard Screw terminal (M3.5×37) EPD-37A / EPD-37 Spring‑up / standard General purpose terminal DTP-3C / DTP-4C — Signal monitor (64‑bit / 32‑bit) CM-64L / CM-32L — Connector conversion board (96pin→37pin×2) CCB-96 — AC‑DC power adaptor (5VDC, 2A) POA200-20-2 For self‑power operation DC‑DC power supply unit POW-DD10GY DIN rail mount * Various cables and terminal blocks available.
