ABB RXIDK 2H 1MRK000838-HA 双通道模拟输入

ABB RXIDK 2H 1MRK000838-HA 双通道模拟输入

该型号与市场上其他型号的不同之处在于，每个通道均可配置，一个通道支持定位器Q控制(AO)，另一个通道支持位置监控(A)。定位器确保致动器进入控制系统指定的位置。它们通常配备有模拟位置指示器，其反馈确认位置规范已经执行。

例如，这些可以是冲程或旋转角度，通常以4-20mA信号的形式提供，并反馈给控制系统。以前，输入和输出信号需要单独的隔离器模块。随着新模块的推出，这两种功能首 次可以在一个设备中使用。

KCD2-SCS-EX2是一种本质安全屏障，可用于危险区域应用(经ATEX、IECEx和UL认证)。还提供用于安全区域应用的非Ex信号调理版本。对于每个版本，有一个螺钉端子或弹簧端子与推入连接技术的选择。根据IEC61508 ed2(tuV Rheinland ),这些模块也适用于SIL2(SC3)以下的应用。

What makes this model different from others on the market is that each channel is configurable, with one channel supporting locator Q control (AO) and the other supporting position monitoring (A). The positioner ensures that the actuator enters the position specified by the control system. They are usually equipped with analog position indicators whose feedback confirms that the position specification has been implemented.

For example, these can be strokes or rotation angles, which are usually provided in the form of a 4-20mA signal and fed back to the control system. Previously, separate isolator modules were required for input and output signals. With the introduction of the new module, these two functions can be used in one device for the first time.

KCD2-SCS-EX2 is an intrinsically safe barrier for hazardous area applications (ATEX, IECEx and UL certified). Non-ex signal conditioning versions are also available for secure area applications. For each version, there is a choice of screw terminal or spring terminal with push-in connection technology. According to IEC61508 ed2(tuV Rheinland), these modules are also suitable for applications below SIL2(SC3).
