• 支持工业标准现场设备连接（2或3线）
• 标准DIN导轨兼容
• 操作电压范围为18vdc到28vdc
• 现场电源分为5组，每组8个通道

作用特征：

• 多功能性：支持多种现场设备的接入，包括产生模拟和数字输入信号的设备，以及需要高达28 Vdc的数字信号的输出设备
• 灵活性：VFTA的每个通道都是可配置的，可以根据需要实现不同的输入输出配置
• 兼容性：标准DIN导轨兼容，方便安装与连接
• 简单的安装和配置：采用简单的插件保险丝和内置电阻进行配置

应用领域：
ROCKWELL-T8448广泛应用于工业自动化、过程控制、火灾和气体检测及抑制系统等领域

 

The ROCKWELL-T8448 is a multifunctional field terminal assembly (VFTA) primarily designed as a main interface between field devices related to fire and gas detection and suppression. It also serves as an interface for the Trusted Triple Modular Redundancy (TMR) zone interface module T8448. Additionally, it functions as an interface for the Trusted TMR valve monitoring module T8449, with alternating use of its digital outputs to solenoid valves and analog inputs for valve positions

Specifications：
(Note: Specific specifications may vary depending on product models and manufacturer updates.)

• Each VFTA has 40 channels configurable as input or output
• Supports industrial standard field device connections (2 or 3 wires)
• Compatible with standard DIN rail mounting
• Operating voltage range from 18vdc to 28vdc
• Field power divided into 5 groups with 8 channels each

Functional Characteristics：

• Multifunctionality: Supports access to multiple field devices, including those generating analog and digital input signals, as well as output devices requiring digital signals up to 28 Vdc
• Flexibility: Each channel of the VFTA is configurable to meet varying input/output configurations
• Compatibility: Compatible with standard DIN rail mounting for easy installation and connection
• Simple installation and configuration: Uses simple plug-in fuses and built-in resistors for configuration

Application Fields：
The ROCKWELL-T8448 is widely used in industrial automation, process control, fire and gas detection and suppression systems, and other related applications
