IS200DRTDH1A模塊控制器
封閉式I/O卡類(lèi)型
外殼上清楚地標(biāo)有封閉式I/O卡類(lèi)型。所有板卡都有電源和內(nèi)部錯(cuò)誤指示燈。八個(gè)通道卡具有清晰可見(jiàn)的通道狀態(tài)LED。通過(guò)精心選擇優(yōu)質(zhì)電子元件和使用保形涂層，所有板卡均符合ISA G3腐蝕規(guī)范。大多數(shù)DI卡上都有脈沖計(jì)數(shù)器。支持的最大頻率從交流信號(hào)的0.1 Hz到24V直流輸入的75或120 Hz不等。對(duì)于高達(dá)50 KHz的脈沖計(jì)數(shù)，請(qǐng)使用多功能卡的高速脈沖輸入。DeltaV系統(tǒng)為日志事件和警報(bào)提供控制模塊級(jí)時(shí)間戳。為了獲得更高的事件分辨率，16通道事件序列DI卡可以提供信號(hào)驅(qū)動(dòng)事件，每個(gè)卡的分辨率為+/-0.25 ms，或每個(gè)控制器的分辨率為1 ms。

Enclosed I/O card type
Enclosed I/O card types are clearly marked on the enclosure. All boards have power and internal error indicators. Eight channel cards have channel status LEDs that are clearly visible. By carefully selecting high-quality electronic components and using conformal coatings, all boards meet ISA G3 corrosion specifications. Most DI cards have pulse counters. The maximum supported frequencies range from 0.1 Hz for AC signals to 75 or 120 Hz for 24V DC inputs. For pulse counting up to 50 KHz, use the high-speed pulse input of the multi-function card. The DeltaV system provides control module level timestamps for logging events and alerts. In order to obtain higher event resolution, 16 channel event sequence DI cards can provide signal driven events, with a resolution of+/-0.25 ms for each card or 1 ms for each controller.
Functional system
For more information about event sequence data collection and system options for this feature, see Event Sequence PDS. DeltaV M Series Traditional I/O October 2022 www.emerson com/DeltaV 4 I/O cards Redundant redundant I/O cards are available for critical applications. The same board can be used for simplex or redundant applications. When installed on two wide redundant terminal blocks, the controller identifies the boards as redundant pairs. The controller scans each card and determines which card acts as the active interface. When a fault is detected, the system automatically switches to the standby I/O card.
