The 1794-VHSC Flex I/O module delivers intelligent high-speed counting for demanding applications. This module provides critical signals to compatible controllers with EtherNet capability. It performs accurate counting for various industrial processes and machinery. The module uses a 5V DC input with a <0.25 mA off-state current. Its input on-state current exceeds 5mA for reliable signal detection.
Why Choose the 1794-VHSC for Your Application?
The 1794-VHSC offers two input channels with two groups of three inputs. Each channel supports multiple encoder modes including 5V DC terminations. This flexibility allows integration with many different sensor types and systems. The module achieves an impressive input frequency of up to 1MHz. Engineers trust this module for precise speed and position measurement tasks.
This module reduces system costs by combining counting and output functions. It has two isolated output groups for direct actuator control. The output supply voltage range is 10-31V DC for flexibility. It dissipates only 5.0W at 31.2V DC maximum. This low power consumption helps manage thermal loads inside enclosures.
Installation Guide for the 1794-VHSC Module
You must install the 1794-VHSC on a compatible terminal base unit. Use either the 1794-TB3G or 1794-TB3GS base for proper operation. The module dimensions are 3.7in x 3.7in x 2.7in when installed. This compact size fits easily into existing Flex I/O racks. The module operates between 0 and 55 °C temperature range.
Connect an external power supply with 24V DC nominal voltage. The supply range must be 19.2-31.2V DC for reliable operation. The power supply demands a current of 100mA at 24V DC. The module draws 75mA at 5V DC from the Flexbus. Always verify the key-switch position is set correctly before powering up.
Wiring requires attention to the input off-state voltage specifications. The off-state voltage is <1.8V DC for reliable signal detection. Ensure input off-state current remains below 0.25 mA. The input on-state current must exceed 5mA for proper counting. These thresholds guarantee accurate high-speed counting performance.
