CM2201 电路管理系统 基于微处理器的数字控制和监控系统

尼尔森单点电路管理系统(简称“CM-2201”)是一种基于微处理器的数字控制和监控系统，专为单机或联网电热跟踪应用而设计。

该系统提供温度控制和加热电缆监控，同时向操作人员传达额外的信息，如温度报警，电压和电流报警，接地故障泄漏，传感器故障和通信故障。

系统组件

电路管理系统安装在NEMA 4 ×耐用模制玻璃纤维聚酯外壳中，可以安装在墙上或机架上。

该系统具有双极固态加热器开关，并且环境硬化，适用于各种工厂位置。CM-2201的标准版本可以安装在Class1, Division 2危险场所，没有特殊要求。多达256个单独的系统可以连接到单个RS485数据高速公路，允许与主机设备通信。CM-2201通过Modbus@ RTU协议完全兼容基于PC的通信软件。警报和控制功能可以从中央位置访问。

CM2201特性

易于使用的界面

2行，16个字符/行，字母数字液晶显示，允许使用英语语言提示设置和操作。没有什么神秘的密码或按键指令需要记住。

开/关或比例控制所需的控制模式可以很容易地通过前面选择

面板用户界面。接地故障报警和脱扣设置单独的报警和脱扣设置接地故障中断，允许在电路中断之前对发展中的故障进行报警

-可选的第二个ATD可以很容易地以各种方式配置，包括使用一个RTD /两个RTD和高温切断。

CM2201可编程自动测试周期用户可以选择从1到24小时的间隔，使机组自动检查加热器工作电流和接地故障情况。这允许在需要加热系统之前检测和修复问题。主机通信RS-485 Modbus RTU通信能力包括作为标准功能。

不需要昂贵的“子板”或固件更新。

CM2201 电路管理系统 基于微处理器的数字控制和监控系统

The Nielsen Single Point Circuit Management System (" CM-2201 ") is a microprocessor-based digital control and monitoring system designed for stand-alone or networked thermal tracking applications.

The system provides temperature control and heating cable monitoring while communicating additional information to the operator such as temperature alarms, voltage and current alarms, ground fault leaks, sensor failures and communication failures.

System component

The circuit management system is housed in a NEMA 4 x durable moulded fiberglass polyester housing that can be mounted on a wall or rack.

The system features a bipolar solid state heater switch and is environmentally hardened for a variety of plant locations. The standard version of the CM-2201 can be installed in Class1, Division 2 hazardous sites without special requirements. Up to 256 individual systems can be connected to a single RS485 data highway, allowing communication with host devices. The CM-2201 is fully compatible with PC-based communication software via the Modbus@RTU protocol. Alarm and control functions can be accessed from a central location.

CM2201 features

Easy to use interface

2-line, 16-character/line, alphanumeric LCD display that allows setting and operation using English language prompts. There are no secret passwords or keystrokes to remember.

On/off or proportional control The desired control mode can be easily selected by the previous

Panel user interface. Ground fault alarm and trip Settings Separate alarms and trips set ground fault interrupts to allow an alarm of a developing fault before the circuit is interrupted

The optional second ATD can be easily configured in various ways, including using one RTD/two RTDS and high temperature cut-off.

CM2201 Programmable automatic test cycle Users can choose intervals from 1 to 24 hours, so that the unit automatically checks the heater operating current and ground faults. This allows problems to be detected and fixed before heating the system is needed. Host communication RS-485 Modbus RTU communication capability is included as a standard feature.

No expensive "daughter boards" or firmware updates are required.
