HTP-SC32 MTL HART连接单元
【产品详情】
部件编号 : HTP-SC32
品牌 : MTL Instruments
产品类型 : HART连接单元
集成连接
HTP-SC32 是处理进出现场设备的 HART 维护信号的简单解决方案,通常是首选的主要方法。它用于模拟输入信号,但如果主机系统与HART通信兼容,也可用于模拟输出。
它能够通过其螺丝夹现场和系统端子处理多达 32 个通道,是集成 HART 维护设施的便捷方式。HTP-SC32 提供了一个独立的解决方案,因为 MTL4850/54 HART 多路复用器已经板载,只需要直流电源和连接到主机管理 PC 的简单 RS485 链路即可开始使用。
每个通道提供两个端子,可以连接到2线制变送器、4/20mA电流环路或电压输入。每个通道都是隔离的,因此可以连接到模拟环路中的任何合适点,并且输入和输出类型可以混合使用。
HART信号必须端接成>240的阻抗,因此在电路板上设置并联电阻器(通常为250)或串联电阻器(如果连接点的输入阻抗为<240)。
无并联电阻器,零欧姆链路串联安装(用于具有 250 输入阻抗或 HART 兼容输出的电流输入)

Integrated connection
The HP-SC32 is a simple solution for handling HART maintenance signals to and from field equipment and is often the primary method of choice. It is used to simulate input signals, but can also be used to simulate outputs if the host system is compatible with HART communication.
Capable of handling up to 32 channels through its screw clamp field and system terminals, it is a convenient way to integrate HART maintenance facilities. The HTP-SC32 provides a standalone solution because the MTL4850/54 HART multiplex is already onboard and only requires DC power and a simple RS485 link to the host management PC to get started.
Each channel provides two terminals that can be connected to a 2-wire transmitter, a 4/20mA current loop or a voltage input. Each channel is isolated, so it can be connected to any suitable point in the analog loop, and input and output types can be mixed.
The HART signal must be terminated with an impedance of >240, so a parallel resistor (usually 250) or a series resistor (if the input impedance at the connection point is <240) is set up on the board.
No shunt resistors, zero ohm link installed in series (for current inputs with 250 input impedance or HART compatible outputs)
