product description
I. Product Overview
The YS1700-000A34 is a programmable indication controller launched by Yokogawa, specifically designed for industrial environments. It features a programmable memory that enables it to perform logical operations, sequential control, timing, counting, and arithmetic operations. Through digital or analog inputs and outputs, it can control various types of machinery or production processes.
Main Features
High Reliability: The YS1700-000A34 inherits the high reliability of Yokogawa’s products and can operate stably in harsh industrial environments.
Strong Computing Power: It supports calculations using engineering units and floating-point mathematics, and can perform logarithmic, temperature/pressure correction, and other complex operations.
Flexible Programming Capability: Function blocks (subroutines) can be saved and reused, and user-defined programming is supported to meet various complex control requirements. At the same time, passwords can be assigned to user programs to prevent unauthorized access.
Rich Communication Interfaces: It supports Ethernet communication (Modbus/TCP), RS-485 communication (Modbus, point-to-point), and DCS-LCS communication, facilitating data exchange with upper-level computers or other devices.
Modular Design: It adopts a modular structure, is small in size and light in weight, making installation and maintenance easy. Meanwhile, the rich I/O interface modules provide strong expansion capabilities, meeting control requirements of different scales.
Technical Specifications
Input/Output: Supports various types of inputs, such as mV input, thermocouple input, RTD input, potentiometer input, isolated input, 2-wire transmitter input (insulated/non-insulated), and frequency input, etc. The output type is determined by the specific configuration.
Communication Interface: Standard Ethernet communication (Modbus/TCP) interface is provided, and RS-485 communication (Modbus, point-to-point) and DCS-LCS communication interfaces are optional.
Display and Operation: Equipped with a full dot-matrix LCD display, supporting multiple window displays for easy viewing and operation by users.
Programming Software: Utilizes the YSS1000 setting and programming software, offering both graphical (function block) and text-based programming methods, providing flexible and convenient programming.
Application scenario
The YS1700-000A34 can be widely applied in various industrial control fields, such as chemical engineering, petroleum, power, pharmaceuticals, etc. It can precisely control parameters like temperature, pressure, flow rate, and liquid level, thereby enhancing the stability and efficiency of the production process.
