2 Switches, Indicating Gage, and Transmitter in One Package
EDA系列电子压力控制是一种非常通用的紧凑封装，可以在一个系统中取代一个单独的压力表，两个开关，和一个变送器，节省资金，安装时间，和面板空间。EDA集成了两个SPDT继电器，在控制或报警使用的范围内，开关点完全可调。正面有LED指示灯的开关状态和一个大背光两线显示过程值和指示单位。简单的菜单结构，两行显示和外部编程按钮，编程容易。耐风雨外壳是各种应用的理想选择，具有面板安装，冲洗安装，或管道安装能力。功能包括零点设置，可调衰减，菜单锁定，峰值和山谷指示，可移动终端块，可调时间延迟，可缩放发射机输出。
应用及案例
• Process control
• Compressor control
• Filter status
• Duct or building static pressure
• Damper and fan control
产品特色
• Display Units: psi, kg/cm², bar, in Hg, ft w.c., kPa, MPa, %FS, in w.c., mbar, cm w.c., mm Hg, or oz/in² (choices depend on range).
• Test Mode: Simulates input over the range without pressuring to easily test switches and transmitter output feature.
• Fail-safe: For sensor failure, over pressure, high temperature limit, low temperature limit, or keypad short. User chooses if relay is de-energized, energized, or no action. With transmitter option, user chooses an output of 3.6 mA 22 mA, or no action.
• Alternation: Selectable alternation of set points between the relays for even wear on duplex pump applications.
• Versatile Compact Package: Can replace a separate gage, two switches, and a transmitter in a system saving, money, installation time, and panel space.
• Fully Programmable: To meet simple or complex application needs.
• Weatherproof Housing: Ideal for a wide variety of applications with panel mount, flush mount, or pipe mount ability.
