DRL-DPM-BKF Woodhead通信模块 起到连接器功能 有1个输出通道

产品功能

Modicon通道模拟输出模块设计用于控制可调频率驱动器、定位阀、阻尼器等。每个通道均可独立配置,以提供电压或电流环路输出。

为了正常工作,模块需要来自外部电源(250mA @ 24VDC)的电源。当不使用外部电源时,模块从内部总线获取电源并给出错误的读数。请勿将此模块在机架中未通电。

模块具有开路电流回路（(断线)检测功能，并通过LED和可访问寄存器发出警告。可以配置为在与CPU的通信丢失超过1秒,CPU停止或断电时保持最后一个值。模块前面有一个琥珀色LED，闪烁指示模块故障。

模块前方顶部的绿色LED指示模块准备就绪。当数据通过通道发送时,每个通道上的绿色LED将保持亮起或快速闪烁。在电流模式每个通道上的红色LED表示检测到开路电流环路(断线)或高环路阻抗(>500Q)。高完整性模拟输入模块专为单一和冗余配置而设计。

Product function

The Modicon channel analog output module is designed to control adjustable frequency drivers, positioning valves, dampers, etc. Each channel can be configured independently to provide voltage or current loop output.

In order to function properly, the module requires a power supply from an external power supply (250mA @ 24VDC). When the external power supply is not used, the module takes power from the internal bus and gives an incorrect reading. Do not leave this module unpowered in the rack.

The module has an open current loop (break) detection function and alerts via leds and accessible registers. It can be configured to hold the last value when communication with the CPU is lost for more than 1 second, and the CPU is stopped or powered off. There is an amber LED on the front of the module that blinks to indicate module failure.

The green LED at the top of the front of the module indicates that the module is ready. As data is sent through the channels, the green leds on each channel will remain lit or flash rapidly. A red LED on each channel in current mode indicates the detection of an open current loop (broken line) or a high loop impedance (>500Q). High integrity analog input modules are designed for single and redundant configurations.
