High-Speed DC Input Performance
The NV1X1604 digital input module provides 16 high-speed DC inputs for monitoring field devices and sensors. This module accepts a wide voltage range from 19.2 VDC to 28.8 VDC, ensuring compatibility with standard 24 VDC industrial control systems. Each input channel draws a nominal current of 7 mA, which imposes a minimal load on the field power supply.
The module features a fast 0.5 ms ON response time and a 1.0 ms OFF response time. Consequently, this digital input module excels in high-speed counting, position sensing, and rapid machine sequencing applications. Users can configure each group of eight inputs independently for sink or source wiring, which provides excellent flexibility for different sensor types.
Physical Design and Installation Details
This digital input module occupies a single slot in the MICREX-SX base rack and measures only 45 mm in width. The 0.14 kg weight makes handling easy during installation and replacement procedures. A 20-point removable screw terminal block dominates the front panel, offering secure connections for all field wires.
Sixteen green LEDs line the front face, with each LED indicating the real-time status of its corresponding input channel. Therefore, maintenance personnel can verify sensor operation and wiring integrity at a glance. The photocoupler isolation provides robust protection against electrical noise and voltage spikes commonly found in factory environments.
Power Requirements and Environmental Specifications
The NV1X1604 draws a modest 100 mA from the 5 VDC backplane, which minimizes heat generation within the control rack. This digital input module operates reliably across an ambient temperature range of 0°C to 55°C. It also withstands humidity levels from 10% to 90% (non-condensing) and tolerates vibration up to 5G at 10-150 Hz.
