Product Details
The 1771-VHSC is a high-speed counter module developed by AB/Rockwell Automation. The 1771-VHSC module has 8 digital outputs isolated in 2 groups, 12 digital inputs (3 per counter) and a 100-microseconds module update period.
The 1771-VHSC module comes with 4 input channels configured for the rate mode, encoder mode, counter mode, and the period/rate mode. It has a programmable count value of 0 to 999,999. This high-speed module is also delivered with 2 input types (differential and single-ended inputs), which is for a 2-phase encoder mode (X1 and X4) with selectable input frequencies of 250 KHz and 500 KHz in the rate/period or rate/measurement mode. It can rise up to 1 MHz in the single-channel counter mode selected by the electromechanical switch. In addition, this I/O module also provides block transfer programming capabilities that perform interface signals and high-speed counting with any PLC. Besides, the 1771-VHSC PLC 5 module counts pulses from encoders such as AB Bulletin 845H, P, L, E, P and K, pulse generators and mechanical limit switches or proximity switches and it returns either a count or frequency rating in a binary or BCD format.

WATER SEWAGE SOLUTION
People usually refer to water treatment, which mainly includes sewage treatment and water treatment, while sewage treatment is divided into industrial wastewater treatment and domestic water treatment.
For the control needs of the water treatment industry, the performance characteristics of PLC-type controllers are the most suitable for this industry.
Therefore, it has also been widely used in water treatment and distribution control systems.
The task of water treatment is to process the raw water so that the water quality meets the requirements of domestic or industrial water. The common process of making tap water is mainly divided into the following steps.
Raw water transport: The process of transporting water from a river or lake to a water treatment plant, usually consisting of several water pumping stations.
