DS200PTBAG1AEC模块备件
低电平输入
使用霍尼韦尔PMIO LLMUX FTA。每个FTA支持16个通道。支持两种类型的LLMUX FTA。一个提供16个RTD输入。另一个提供16个TC或MV输入。FTA的任何组合可用于提供所需TC、mV或RTD点的混合。显著特点•TC和RTD操作•远程冷端能力•1秒PV扫描，带OTD保护•可配置OTD保护（见下文）•温度点可按16点增量添加温度支持温度输入LLMUX支持现有固态PMIO LLMUX FTA。PMIO LLMUX FTA支持RTD和热电偶（TC）输入。以1秒的速率从所有点收集温度变量。1秒更新包括在温度变量传播之前对开路热电偶检测（OTD）（见下文）的可配置检查。所有TC输入均使用冷端补偿（CJT）装置进行补偿。采样和开放式传感器检测温度多路复用器支持RTD和热电偶，在PV交付前进行开放式传感器的检测（如有配置）。在OTD配置激活的情况下，在同一测量窗口内执行OTD循环的同时，对PV进行采样和保持。如果OTD为负，则PV通过系统向上传播。
输入通道软故障被设置
如果OTD为正，则PV被设置为NAN，并且输入通道软故障被设置。这样，对于因热电偶开路而无效的PV值，不会发生不适当的控制动作。PV采样/报告不会导致OTD处理的额外延迟。详细规格–低电平输入多路复用器参数规格输入/输出型号CC PAIM01 PMIO FTA型号1 MU-TAMR04、TAMT04、TAMT 14输入型热电偶和/或RTD输入通道64完全隔离通道间、通道间PM和通道间电源，共16个通道增量。输入扫描速率1秒由IOM固定（最多64个通道/秒）通道带宽0至4.7 Hz（-3 dB）标称输入范围（仅限TC）-20至+100毫伏最大正常模式连续输入无损坏（配置任何热电偶类型）-10至+10伏（TC）-1至+2伏@100毫安（RTD）增益误差（-20至+10毫伏范围）0.050%满量程最大温度稳定性TC，毫伏输入+/-20 ppm每摄氏度最大RTD输入+/-20 ppm/摄氏度最大长期漂移500 ppm
Low level input
Use Honeywell PMIO LLMUX FTA. Each FTA supports 16 channels. Two types of LLMUX FTA are supported. One provides 16 RTD inputs. The other provides 16 TC or MV inputs. Any combination of FTA can be used to provide the required mix of TC, mV or RTD points. Remarkable features • TC and RTD operation • Remote cold end capability • 1-second PV scanning with OTD protection • Configurable OTD protection (see below) • Temperature point can be added in 16 point increments to support temperature input LLMUX to support existing solid-state PMIO LLMUX FTA. PMIO LLMUX FTA supports RTD and thermocouple (TC) inputs. Collect temperature variables from all points at a rate of 1 second. The 1-second update includes a configurable check of the open thermocouple detection (OTD) (see below) before the temperature variable propagates. All TC inputs are compensated by the cold junction compensation (CJT) device. The sampling and open sensor detection temperature multiplexer supports RTD and thermocouple, and carries out open sensor detection (if configured) before PV delivery. When OTD configuration is activated, PV is sampled and held while OTD cycle is executed in the same measurement window. If OTD is negative, PV propagates upward through the system.
Input channel soft fault is set
If OTD is positive, PV is set to NAN and input channel soft fault is set. In this way, improper control action will not occur for PV value invalid due to thermocouple open circuit. PV sampling/reporting does not cause additional delays in OTD processing.
