Reliance 57C410D控制4通道電路
控制輸出兩個4–20 mA或20–160 mA可配置執(zhí)行器輸出，帶線性化曲線可供使用。致動器1默認(rèn)為主高壓進(jìn)口閥但兩個致動器通道都可配置為HP、HP2（用于分離范圍）或讀數(shù)八個C型繼電器觸點(diǎn)輸出可用。第一個通道是專用的為跳閘輸出，可配置為用作完整的總結(jié)跳閘或跳閘繼電器輸出（不包括外部跳閘輸入）。其他的七個是可配置繼電器，但第二個繼電器默認(rèn)為報警摘要輸出。可以對每個繼電器進(jìn)行編程，以提供與條件狀態(tài)相關(guān)的觸點(diǎn)如第一個列表中所列，或者可以根據(jù)第二個列表控制接口HMI、工廠DCS或其他可用的完整Modbus信息列表控制接口。三個物理端口可用于此通信方法，2個以太網(wǎng)（RJ45）端口和1個串行端口。串行端口協(xié)議可以是ASCII或RTU，通信可以是RS-232或RS-485以太網(wǎng)鏈路可以在ENET端口1或2上配置為TCP或UDP。

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).
