美国SEL-2505 远程 IO 模块 8 个数字输入8 个数字输出一个光纤通信端口
SEL-2505 远程 I/O 模块具有 8 个数字输入、8 个数字输出和一个光纤通信端口。在室外或远程设备与控制大楼之间使用两根光纤而不是 32 根电线,以降低成本、提高安全性并提高可靠性。或者,将 SEL-2505 连接到保护继电器上的光纤端口或收发器,以添加数字 I/O。将 SEL-2505 I/O 连接到继电器 I/O 以添加 SEL 镜像位远程保护。
保护和监控 —使用现有继电器的触点输入和输出添加简单的总线保护。为现有的 2 端和 3 端线路应用提供安全的 Pilot 通信。添加本地或远程跳闸和闭合线圈监控功能。
I/O 触点扩展 —经济地扩展与 Mirrored Bits 通信兼容的 SEL 继电器上的 I/O 触点数量。
全面的设备兼容性 —将 Mirrored Bits 通信添加到任何保护继电器(数字或机电)或其他智能电子设备 (IED) 中,以实现基于通信的***保护。
增强的系统可靠性 —通过使用光纤链路代替传统的配电盘布线,减少或消除 IED 之间的接地电位上升。
SEL2505#0101
Protection and Monitoring
Add simple bus protection using contact inputs and outputs from existing relays. Add secure pilot communications to existing two- and three-terminal line applications. Add local or remote trip and close coil monitoring capability.
Integration
Expand the I/O of SEL relays that are Mirrored Bits compatible without modification to the control panel face. Make I/O status from any relay available to SEL Mirrored Bits schemes.
Safety
Replace control wiring to outside cabinets with fiber-optic cable to reduce dc ground exposure.
Dependability
Use the communications monitoring feature to alarm when fiber-optic control cabling has been damaged, disturbed, or altered.
High Reliability and Rugged Design
Built to the same high standards as SEL protective relays, the SEL-2505 withstands vibration, electrical surges, fast transients, and extreme temperatures, meeting stringent industry standards. The printed circuit boards are conformal-coated to provide an additional barrier to airborne contaminants, such as hydrogen sulfide, chlorine, salt, and moisture.
Savings
Reduce project costs by using two fibers instead of 32 large-diameter wires, with less material expense, reduced trench and raceway requirements, and less labor for design, documentation, installation, testing, and maintenance.
