What are the primary benefits of using a distributor?

The main benefit is the ability to receive measurement signals and convert them into various analog signals or CAN data while supplying operating power (such as DC 24V) to 2-wire transmitters like water level meters. This eliminates the need for a separate power supply and keeps wiring simple.

Is it possible to automatically control pumps or indicator lights based on the water level?

Yes, it is possible. By utilizing the alarm output function, you can individually configure conditions such as 'Pump OFF when water level is 90% or higher, and ON when 40% or lower'. Since the signal can be directly used for pump ON/OFF control at the same time as measurement, it helps simplify the system.

What is the best way to import measurement data into a PC or higher-level system?

Models supporting CAN communication (such as the PSA series) are highly recommended. Unlike the command-response method, these models automatically output data at every update interval, which significantly reduces program development costs. High-speed analog output with up to a 1ms update rate can also be used simultaneously.

Can on-site setting changes and data verification be performed easily?

Selecting a type with a display (such as PSA-4801/2401) allows you to visually check converted values directly on-site. Additionally, they come standard with a USB Type-C port, enabling easy configuration management and logging from a PC using the free software LINKSHIP.

Water Level Measurement & Control for Tanks, etc. Using Distributors

Supplies driving power to 2-wire transmitters such as water level meters and level sensors using a distributor, and converts the received signals into DC current/voltage signals.
In addition, alarm outputs can be configured based on water level or flow rate (e.g., OFF at 90%, ON at 40%) to be utilized as pump ON/OFF signals.

Capabilities

For water level measurement in tanks, signals from 2-wire transmitters (sensors, etc.) can be converted into analog signals to import data.

Power supply to the 2-wire transmitter can be performed simultaneously.

Analog output can achieve up to a 1ms update rate.

Equipped with 2 to 4 alarm outputs (optional), which can be used as control signals for turning pumps or indicator lights ON/OFF.

While non-CAN communications acquire measurement data via a command-response method, CAN communication automatically outputs data at each update interval, reducing program development costs (depending on the selected model).
