HE693ADC405 4-channel analog input module Analog signals can be accurately converted to digital data

Desciption

The HE693ADC405 is a 4-channel analog input module manufactured by Horner Electric for programmable logic controllers (PLCS) in industrial automation applications.

Here's a breakdown of its features and applications:

Features:

The analog voltage signal from the sensor (typically in the +/ -10 VDC range) is converted into a digital value for the PLC to understand and process.
These voltage signals represent various process variables, such as pressure, temperature flow, or level.
Provides 4 independent channels for simultaneous measurement of up to 4 sensors.
Applications:

Used in a variety of industrial automation processes where PLCS need to monitor and control variables based on analog sensor data. Here are some examples:
Factory automation: temperature monitoring, pressure, and processes in production processes such as chemical mixing or assembly lines.
Building Automation systems: Integrate the temperature and pressure sensors of HVAC equipment into the building management system.
Data acquisition systems: Collect analog sensor data from a variety of sources and make it accessible to PLCS for analysis and control decisions.
Main features:

4 channel analog voltage input (+/ -10 VDC).
14-bit resolution for accurate conversion of analog signals into digital data.
Isolation between channel and ground to improve noise resistance.

The HE693ADC405 has four analog input channels, including 14-bit resolution. Two models are available, the HE693ADC410 with 1500VAC (RMS) isolation and the HE693ADC405 with 500VAC (RMS) isolation. Isolation levels are inter-channel and channel-to-ground. These modules convert the voltage signal into a digital value (-32,000 tp +32,000), which can be found directly in the %AI table of the PLC CPU. Each individual channel (there are four channels) includes a programmable set point. Its level is set in the PLC program by four %AQ output registers. When the analog input value reaches or exceeds the set value, the corresponding digital input %I is energized. The first four %Is represent each of the four input channel set point alarms.
