T8480C T8480 可信TMR模拟输出模块

T8480C T8480 可信TMR模拟输出模块

Trusted®TMR模拟输出模块可连接40个现场设备。在整个模块中执行三次诊断测试，包括对投票输出通道每个部分的电流和电压的测量。还对卡接和卡脱故障执行测试。容错是通过模块内的三模冗余(TMR)架构实现的，用于40个输出通道中的每一个。

提供现场设备的自动线路监控。该功能使模块能够检测现场接线和负载设备中的开路和短路故障。

该模块提供板载事件序列(SOE)报告，分辨率为1ms。状态的输出更改触发SOE条目。模块上的电压和电流测量自动确定输出状态。

本模块不允许直接连接到危险区域，应与本质安全屏障装置一起使用。

T8480C T8480 可信TMR模拟输出模块

The Trusted®TMR analog output module can connect to 40 field devices. Three diagnostic tests are performed throughout the module, including measurements of the current and voltage in each part of the voting output channel. Tests are also performed for bonding and tripping faults. Fault tolerance is achieved through a three-mode redundancy (TMR) architecture within the module for each of the 40 output channels.

Provides automatic line monitoring of field equipment. This function enables the module to detect open and short circuit faults in field wiring and load equipment.

The module provides onboard Event sequence (SOE) reports with a resolution of 1ms. The output change of the state triggers the SOE entry. The voltage and current measurements on the module automatically determine the output status.

This module is not allowed to be directly connected to hazardous areas and should be used in conjunction with essential safety barrier devices.

peculiarity

• 40 three-mode redundancy (TMR) output channels per module.

• Comprehensive, automated diagnostics and self-tests.

• Automatic point-by-point line monitoring to detect open and short field wiring and load failures.

•2500V pulsed optical/electrical isolation barrier.

• Automatic overcurrent protection (per channel) without external fuses.

• Onboard Event sequence (SOE) reports with a resolution of 1ms.

• Support for online hot replacement modules through dedicated Companion(adjacent)Slot or SmartSlot(multiple modules in one standby slot) configuration.

Front panel output status Light emitting diodes (leds) at each point indicate output status and field wiring faults.

• Front panel module status led indicates module health and operating mode (Active, Standby, connected).

• For TV certified non-interference applications, refer to Safety manual T8094.

• Output is powered by 8 isolated groups. Each of these groups is a power group (PG).
