16‑channel open‑collector digital output for USB. The DO‑16TY2‑USB delivers 200µsec response, 28VDC/40mA per channel, and surge protection. Bus‑powered, compact, and equipped with easy‑wire terminal connectors. Windows/Linux drivers included. From Contec Americas.
The DO‑16TY2‑USB is a USB2.0 bus‑powered terminal that adds 16 channels of high‑speed open‑collector digital output to any PC. With a 200µsec response time and 28VDC/40mA per channel, it is ideal for driving relays, LEDs, solenoids, and other low‑power loads. The unit features surge protection on all output lines and easy‑wire terminal connectors.
Open‑collector outputs – each output must be pulled up at the external device (no internal pull‑up). Surge absorption diodes protect against voltage spikes when driving inductive loads.
Designed for portability and ease of integration. The DO‑16TY2‑USB is powered directly from the USB bus – no external power supply required. Its compact form factor (64×62×24 mm) and screw‑type terminal connectors simplify wiring in benchtop and industrial setups.
