X20DI4760 B&R X20 System Digital Input Module

Product parameters

Input type: 4 NAMUR inputs.

Electrical isolation: Channels are isolated from the bus, but not from each other.

Insulation voltage: The insulation voltage between the channel and the busbar is 500V.

Input characteristics: Open-circuit detection current less than 350μA, short-circuit detection current greater than 7mA, open-circuit voltage 8.05V±0.33%, internal resistance of the switching amplifier 1kΩ±1%, maximum short-circuit current 8.2mA.

Input delay: ≤310μs when 1 input is activated, ≤450μs when 2 inputs are activated, ≤570μs when 3 inputs are activated, and ≤735μs when 4 inputs are activated.

Operating temperature: -25 ℃ to 60℃ when installed horizontally, and -25 ℃ to 50℃ when installed vertically.

Storage temperature: -40℃ to 85℃.

Protection grade: IP20 protection grade in compliance with EN 60529 standard.

Function

Status indication: Each channel is equipped with I/O function status indication, which can perform open circuit and short circuit detection. Additionally, there are module operation status and error indications, which can be visually viewed through LED status indicator lights and software.

Event counting: It is equipped with 4 event counters, with signal forms being symmetrical square waves or the corresponding minimum pulse duration. Each rising edge can be counted, and the counter size is 8 bits.

Application scenarios

Petrochemical industry: NAMUR input is suitable for hazardous locations and can be used in the petrochemical industry to monitor the status of on-site equipment in flammable and explosive environments, such as the input and collection of signals from pressure switches, temperature switches, etc.

In the metallurgical production process, it can be used to detect various switch signals, such as the opening and closing status of valves and limit switch signals, to ensure the normal operation of the production process and the safety monitoring of equipment.

Other industrial fields: It can also be applied to other industrial scenarios that have high requirements for digital input, exist in certain harsh environments, or need to meet specific electrical safety standards, such as the automation control systems in the power, pharmaceutical, food and beverage, and other industries.
