1761-L10BWA 小型MicroLogix PLC模块AB署理

PIC16C54芯片处于睡觉状况,当任一按键按下,将唤醒PIC16C54进行键盘处理。本例中,按下SW1,点亮绿灯,按下SW2,点亮红灯。 进入睡觉时,应将键扫描输出线SCAN1,SCAN2置为低电平,进入睡觉后,电容C被充沛充电,使MCLR坚持高电平。当有按键按下时,电容C经电阻R2或R3放电,其两头电压敏捷下降(下降时刻约为1ms),从而使MCLR下拉为低电平,进入复位。唤醒PIC16C54的复位时刻(大约为18ms),也应更小于键按下的较小时刻(大约为50-100ms)。 每次扫描即SCAN1,SCAN2为低电平的时刻大约为10ms,当键处理程序完成后,程序对键盘循环扫描直至键开释,然后将SCAN1,SCNA2输出置为低电平,单片机从头进入睡觉。 1761-L10BWA 1761-L10BWA   咱们首要为您供给以下产品:   (1)署理..美国(GE)DCS和PLC产品如:90/30,90/70,VersaMax,PACSystemsRX3i, PACSystems RX7i等系列;   (2)署理..美国..(A-B) PLC产品以及相关低压产品如:1756系列,1785系列,1746系列,1747系列,2711,变频器,软启动等系列;   (3)经销..瑞士..ABB.. 机器人系列,ABB Advant OCS,ABB Procontic PLC CPU   (4)经销..法国….施耐德.. 140莫迪康昆腾系列处理器,内存卡,电源模块等。   (5)经销..德国…西门子..Siemens MOORE,S5,S7等   (6)署理..美国..英维思 ESD系统 FOXBORO,Invensys Triconex电源模块,板卡等产品;   咱们首要为您供给以下服务:   1. 我司出售的各种类型配件,产品一般是原装,全新的产品;假如是功用正常的旧品,咱们会清晰声明;   2. 抱负的售后服务,产品保质期为到货后一年;假如不是使用不当,客户能够将有问题的产品寄回我司(需求完好的原包装),我司会将产品返给厂家进行修理;   3. 我司免费向已树立供货联系的客户供给产品使用上的专业技术支持。   4. 停产备件再制作服务,将客户供给的产品送至厂家修理中心进行再生产或许再晋级服务,保证其修理质量。   ——————————–   供货商简介:   厦门慧星交易有限公司,2013年建立,百万注册资金,位于福建-厦门市,首要从事自动化国际交易,产品调试和控制系统开发。   发布人:李享   电话:*** / ***   QQ:3118846616 微信号:***   传真:*** (请补白&李工&收)   邮编:361100 E-mail: 3118846616@qq.com   以下是我公司部分库存:US/DE Ship! 3pcs Nema23 stepper motor425oz-in 3A 112MM for cnc kit mill LONGS  慧星库存编号:693-94  1pcs INDUSTRIAL ICOP VSX-6150E-V2CPU BOARDS Vortex86SX  慧星库存编号:439-72  (NEW) Omron Proximity Sensor 12-24VDC E2E-X5MF1-M1  慧星库存编号:357-24  (NEW) Omron Inductive Proximity Switch E2E-X5MF1-M1  慧星库存编号:259-81  Anreihen clamp for PCB mounting 3-pole Wire guard Screw M2 Steel 6A/250V AC  慧星库存编号:28-20  SIEMENS 3TH20 22-0BB4 CONTROL RELAY NEW IN BOX  慧星库存编号:220-77  RELIANCE ELECTRIC R20E8000 DC TACOMETER-GENERATOR (1C6)  慧星库存编号:3085-22  0-10mH2O with 11m Cable Throw-in Type Liquid Level Transmitter Level Transducer  慧星库存编号:732-99  Allen Bradley Powerflex AC Drive 1/4HP 22A-B1P5N104 NEW  慧星库存编号:974-21  PT100 Thermometers Senser Probe 3 WIRE -200 to 450°C  慧星库存编号:43-93  Digital Temperature Meter for RTD PT100 Temperature Sensors (C / 12VDC)  慧星库存编号:48-82  NEW – Omron Proximity Sensor E2A-M30KS15-WP-C1 5M  慧星库存编号:649-19  UNIVERSAL DYNAMICS PCB-098A GRAPHIC DISPLAY CARD STOCK # 84369 (3C4)  慧星库存编号:1812-16  6SE6420-2UD17-5AA1 SIEMENS MM 420 DRIVE for 0-75kW motor input 3AC 380-480V  慧星库存编号:1297-03  Omron CP1H-X40DT1-D PLC Programmable Logic Controller New in sealed box  慧星库存编号:2266-82  1PC Used Yaskawa SGDH-04AE  慧星库存编号:649-52  Large Digitran Numeric Thumbwheel Switch 4 Section 16 Position 0-15 Hex – NOS  慧星库存编号:227-27  (NEW) Omron Inductive Proximity Switch E2E-X2Y1-M4  慧星库存编号:259-81  ELTRA EL63A25S5/28P8X6MR ROTARY OPTICAL ENCODER (3C)  慧星库存编号:1162-64  Siemens 3RV1021-1GA10 Motor Protector 230V !
