产品详情内容介绍
Reliance 57C410D控制4通道电路
控制输出两个4–20 mA或20–160 mA可配置执行器输出，带线性化曲线可供使用。致动器1默认为主高压进口阀但两个致动器通道都可配置为HP、HP2（用于分离范围）或读数八个C型继电器触点输出可用。第一个通道是专用的为跳闸输出，可配置为用作完整的总结跳闸或跳闸继电器输出（不包括外部跳闸输入）。其他的七个是可配置继电器，但第二个继电器默认为报警摘要输出。可以对每个继电器进行编程，以提供与条件状态相关的触点如第一个列表中所列，或者可以根据第二个列表控制接口HMI、工厂DCS或其他可用的完整Modbus信息列表控制接口。三个物理端口可用于此通信方法，2个以太网（RJ45）端口和1个串行端口。串行端口协议可以是ASCII或RTU，通信可以是RS-232或RS-485以太网链路可以在ENET端口1或2上配置为TCP或UDP。
键盘和显示器图形显示键输入
前面板显示屏旨在为用户提供多种级别的配置、校准、调谐、操作和监测涡轮机的通道活动操作涡轮机不需要额外的控制面板涡轮机控制功能可以从505的前面板执行。看门狗定时器/CPU故障控制显示屏左前侧的IO锁定和CPU运行状况LED是始终处于与控件背面的LED相同的状态。他们是完全由505控制硬件控制，不受GAP应用程序。
看门狗定时器和CPU故障电路监控微处理器和微处理器存储器。如果微处理器无法复位最后一次复位后15毫秒内，CPU故障控制将激活复位输出。这将重置CPU，断开所有继电器输出，并关闭所有毫安输出。Flex505控制器是现有505产品线的重大升级增强的CPU、图形显示、通信和I/O功能。
注：使用Woodward CAN时，此控制器支持扩展I/O选项分布式I/O节点（RTCnet和LINKnet HT）。

Control Outputs
Two 4–20 mA or 20–160 mA configurable actuator outputs with linearization curves are available for use. Actuator 1 is defaulted to be the main HP inlet valve demand, but both actuator channels are configurable to be HP, HP2 (for split range) or a readout Eight Form-C relay contact outputs are available. The first channel is dedicated to be a Trip output and can be configured for use as a complete Summary Trip or a TRIP relay output (where the External Trip inputs are not included). The other seven are configurable relays, however the second relay is defaulted to be an Alarm Summary output. Each relay can be programmed to provide a contact related to a conditional state as listed in the first list, or it can be triggered as a level-active switch as per the second list
Control Interfaces
A complete Modbus list of information is available for HMI, plant DCS or other control interfaces. Three physical ports are available for this communication method, 2 Ethernet (RJ45) ports and 1 serial port. The serial port protocol can be either ASCII or RTU and the communications can be RS-232 or RS-485. The Ethernet links can be configured as TCP or UDP on either ENET ports 1 or 2. Keypad and Display Graphical Display Key Inputs The front panel display is designed to provide the user with multiple levels of access for configuring, calibrating, tuning, operating and monitoring the turbine operation. No additional control panels are required to operate the turbine, every turbine control function can be performed from the 505’s front panel.
Watchdog Timer/CPU Fault Control
The IO Lock and CPU Health LED’s on the front left side of the display – are always in an identical state as the LED’s on the back side of the control. They are completely controlled by the 505 control hardware and are not controlled by the GAP application. A watchdog timer and CPU fault circuit monitors the operation of the microprocessor and microprocessor memory. If the microprocessor fails to reset the timer within 15 milliseconds of the last reset, the CPU fault-control will activate the reset output. This resets the CPU, de-energizes all relay outputs and turns off all milliamp outputs.
The Flex505 controller is a significant upgrade to the existing 505 product line with enhanced CPU, Graphical display, communications, and I/O functions. Note: This controller supports expanded I/O options when using Woodward CAN distributed I/O nodes (RTCnet and LINKnet HT).
