描述

输出模块的功率放大元件有驱动直流负载的大功率晶体管和场效应管、驱动交流负载的双向晶闸管，以及既可以驱动交流负载又可以驱动直流负载的小型继电器。输出电流的典型值为0.3～2A，负载电源由外部现场提供。
图2-5是继电器输出电路。内部电路使继电器的线圈通电，它的常开触点闭合，使外部负载得电工作。继电器同时起隔离和功率放大作用，每一路只给用户提供一对常开触点。与触点并联的RC电路和压敏电阻用来消除触点断开时产生的屯弧，以减轻它对CPU的干扰。
图2.6是晶体管集电极输出电路。。输出信号送给内部电路中的输出锁存器，再经光耦合器送给输出晶体管，后者的饱和导通状态和截止状态相当于触点的接通和断开。图中的稳压管用来抑制关断过电压和外部的浪涌电压，以保护晶体管，晶体管输出电路的延迟时间<1ms。场效应管输出电路的结构与晶体管输出电路基本上相同。我们这里有您急需的停产备件，优势现货，询不到的，买不到的，请联系我们！绝 对优势，绝 对低价！绝 对正品，优质的产品，一流的服务，充足的库存，欢迎来电询价，我们将会给您最优惠的价格！主营：世界知名品牌的PLC、DCS系统备件模块①Allen-Bradley(美国AB)系列产品》②Schneider(施耐德电气)系列产品》③General electric(通用电气)系列产品》④Westinghouse（美国西屋）系列产品》⑤SIEMENS(西门子系列产品)》⑥销售ABB Robots.FANUC Robots、YASKAWA Robots、KUKA Robots、Mitsubishi Robots、OTC Robots、PanasonicRobots、MOTOMAN Robots。⑦estinghouse（西屋）：OVATION系统、WDPF系统、MAX1000系统备件。⑧Invensys Foxboro（福克斯波罗）：I/A Series系统，FBM（现场输入/输出模块）顺序控制、梯形逻辑控制、事故追忆处理、数模转换、输入/输出信号处理、数据通信及处理等。Invensys Triconex:冗余容错控制系统、基于三重模件冗余（TMR）结构的zui现代化的容错控制器。⑨Siemens(西门子)：Siemens MOORE，Siemens Simatic C1，Siemens数控系统等。⑩Bosch Rexroth（博世力士乐）：Indramat，I/O模块,PLC控制器,驱动模块等。◆Motorola（摩托罗拉）：MVME 162、MVME 167、MVME1772、MVME177等系列。Family CertificationLevel Hardware Manufacturer Board BSP Name68030 Wind River Product Motorola,Inc.Motorola MVME147A mv14768040 Wind River Product Motorola,Inc.Motorola MVME162PA mv16268040 Wind River Product Motorola,Inc.Motorola MVME167PA mv16768060 Wind River Product Motorola,Inc.Motorola MVME172PA mv17268060 Wind River Product Motorola,Inc.Motorola MVME177P/PA mv177683xx Wind River Product Freescale,Inc.M86EN302 FADS fads302en683xx Wind River Product Wind River Wind River SBC360 wrSbc360AMCC 4xx Wind River Product AMCC AMCC 405GP Walnut Board walnutAMCC 4xx Wind River Product AMCC AMCC PPC 440GP Ebony ebonyAMCC 4xx Wind River Product AMCC AMCC PPC 440GX Ocotea ocoteaAMCC 4xx Wind River Product Wind River Wind River PPMC440GP wrPpmc440gpAMCC PPC405xx Uncertified Advanet Inc.A6pci7503 VxWorks 5.5.1 BSP for A6pci7503AMCC PPC405xx Uncertified Advanet Inc.Advme7507A VxWorks 5.5.1 BSP for Advme7507AAMCC PPC440xx Uncertified Advanet Inc.Advme7510 VxWorks 5.5.1 BSP for Advme7510AMCC PPC440xx Not Supported AMCC PPC440SP Evaluation Board(Luan)VxWorks 5.5.1 BSP for amcc440spAMCC PPC440xx Not Supported AMCC PPC440SPE Evaluation Board(Yucca)VxWorks 5.5.1 BSP for AMCC440speAMD Uncertified ADLINK TECHNOLOGY INC.(Ampro)ETX-GX2 VxWorks 5.5.1 BSP for ETX-GX2ARM Other Wind River Product ARM Ltd.ARM Integrator 946ES integrator946esARM Other Wind River Product ARM Ltd.ARM Integrator 966ES integrator966esARM7 Thumb Wind River Product ARM Ltd.ARM Integrator 720T integrator720tARM7 Thumb Wind River Product ARM Ltd.ARM Integrator 740T integrator740tARM7 Thumb Wind River Product ARM Ltd.ARM Integrator 7T integrator7tARM9 Not Supported Fujitsu airman926ej/Fujitsu SoC 802.16 Reference Kit airman926ejARM9 Thumb Wind River Product ARM Ltd.ARM Integrator 920T integrator920tARM9 Thumb Wind River Product ARM Ltd.ARM Integrator 940T integrator940tBroadcom BCM125x Wind River Product Broadcom Corporation Broadcom BCM91250a VxWorks 5.5.1 BSP for bcm1250Broadcom BCM125x Wind River Product Broadcom Corporation Broadcom BCM91250e Sentosa bcm1250eCavium Octeon Wind River Product Cavium Networks CN30XX-EVB-HS5,CN52XX-EVB-MB4-Y VxWorks 5.5.1 BSP for Cavium CN50xx/CN52xxCavium Octeon Not Supported Cavium Networks CN5800-EVB-NIC4,CN5600-EVB-MB12 VxWorks 5.5 BSP for Cavium OCTEON CN58XX,CN56XX/5434R/54XXCeleron Uncertified ADLINK TECHNOLOGY INC.(Ampro)ETX-IM266 VxWorks 5.5.1 BSP for ETX-IM266Celeron Uncertified ADLINK TECHNOLOGY INC.(Ampro)ETX-IM333 VxWorks 5.5.1 BSP for ETX-IM333Celeron Uncertified ADLINK TECHNOLOGY INC.(Ampro)cPCI-3840 VxWorks 5.5.1 BSP for cPCI-3840Celeron Uncertified Advanet Inc.Advme8017 VxWorks 5.5.1 BSP for Advme8017Core 2 Not Supported Emerson Network Power Emerson CPCI-7200 VxWorks 5.5.1 BSP for Emerson CPCI-7200Core 2 Not Supported Intel Corporation Miscowabic Peak VxWorks 5.5.1 BSP for Miscowabic Peak(AMP)Freescale 74xx Wind River Product Freescale,Inc.Freescale Sandpoint with PMC74xx VxWorks 5.5.1 BSP for sp74xxFreescale 74xx Wind River Product Motorola,Inc.Motorola LOPEC-P lopecFreescale 74xx Wind River Product Motorola,Inc.Motorola MCPN765 mcpn765Freescale 74xx Wind River Product Motorola,Inc.Motorola MCPN805 mcpn805Freescale 74xx Wind River Product Motorola,Inc.Motorola MVME5100 mv5100Freescale 74xx Wind River Product Motorola,Inc.Motorola MVME5500 mv5500Freescale 74xx Wind River Product Motorola,Inc.Motorola PRPMC800 prpmc800Freescale 74xx Wind River Product Wind River Wind River PPMC74xx wrPpmc74xxFreescale 74xx Wind River Product Wind River Wind River SBC7410 wrSbc7410Freescale 74xx Uncertified Kontron AG VxG4 Dual and Quad 7410 Computing Node VxWorks 5.5.1 BSP for VxG4
