HIMA H6200A 發(fā)射器電路功能說明
HIMA H6200A 是一款用于工業(yè)自動化安全系統(tǒng)中的模擬輸入模塊，其發(fā)射器電路主要用于接收來自現(xiàn)場儀表（如變送器）的模擬信號，典型為 4–20 mA 電流信號。該電路具有以下關(guān)鍵功能：
1. 變送器供電功能
H6200A 提供內(nèi)部隔離的直流電源，為外部 2 線制變送器供電。電壓通常為 24V，電流受控，以保證供電穩(wěn)定性和安全性。
2. 模擬信號采集
電流信號（如 4–20 mA）通過限流和采樣電路轉(zhuǎn)換為電壓信號，供后續(xù) A/D 轉(zhuǎn)換處理。H6200A 會對輸入信號進(jìn)行線性化處理，轉(zhuǎn)換為控制系統(tǒng)可識別的數(shù)據(jù)格式。
3. 電氣隔離
通過隔離放大器或光電耦合器，實(shí)現(xiàn)信號通道、電源與系統(tǒng)主板之間的電氣隔離，有效防止接地電位差、過壓等干擾傳入控制系統(tǒng)。
4. 故障監(jiān)測
具備以下故障檢測功能：
信號開路檢測（例如變送器斷線）
信號短路保護(hù)
輸入電壓/電流異常報(bào)警
5. 系統(tǒng)集成能力
H6200A 可作為 HIMatrix 或 HIMax 系統(tǒng)的一部分，通過系統(tǒng)后端的安全處理器完成信號的診斷、邏輯運(yùn)算和數(shù)據(jù)上傳。具備冗余設(shè)計(jì)能力，可滿足 SIL3 等級的應(yīng)用需求。

Function Description of HIMA H6200A Transmitter Circuit
HIMA H6200A is an analog input module used in industrial automation safety systems. Its transmitter circuit is mainly used to receive analog signals from field instruments (such as transmitters), typically 4-20 mA current signals. This circuit has the following key functions:
1. Power supply function of transmitter
H6200A provides internally isolated DC power supply to power external 2-wire transmitters. The voltage is usually 24V, and the current is controlled to ensure power supply stability and safety.
2. Analog signal acquisition
The current signal (such as 4-20 mA) is converted into a voltage signal through current limiting and sampling circuits for subsequent A/D conversion processing. H6200A will linearize the input signal and convert it into a data format recognizable by the control system.
3. Electrical isolation
By isolating amplifiers or optocouplers, electrical isolation is achieved between the signal channel, power supply, and system motherboard, effectively preventing interference such as ground potential difference and overvoltage from entering the control system.
4. Fault monitoring
Equipped with the following fault detection functions:
Signal open circuit detection (such as transmitter disconnection)
Signal short circuit protection
Abnormal input voltage/current alarm
5. System integration capability
H6200A can be used as a part of the HIMatrix or HIMax system, completing signal diagnosis, logical operations, and data uploading through the security processor in the system backend. Capable of redundant design to meet the application requirements of SIL3 level.
