1.产 品 详 情 资 料：
主要功能•MPC860微处理器，运行频率为48 MHz。•16 MB RAM，带内部或外部电池备份设施。•12 x S800 I/O单元可以连接到电气模块总线。•四个板载通信端口：–CN1+CN2，以太网端口（IEEE 802.3，10BaseT）–COM3，带调制解调器支持的串行端口（RS-232C）–COM4，用于维修工具的串行端口冗余控制链路，用于冗余配置。•Compact Flash接口，支持加载应用程序和冷保存数据存储器•2 MB闪存PROM（固件存储器）。•16 MB的SDRAM。功耗6 W，典型值11 W（包括对ModuleBus和CEXBus的完全供电，见附录B，功耗）。电流消耗250 mA（最大430 mA）（不包括ModuleBus和CEX总线的供电，见附录B，功耗）。电源输入连接器四针螺纹连接器L+、L-、SA和SB。电源要求输入指定为L+和L-24 V标称电压，在19.2 V DC和30 V DC之间变化。冗余电源状态输入指定为SA、SB的输入•最大输入电压30 V•高电平的最小输入电压15 V•低电平的最大输入电压8 V这些输入是状态输入。阈值级别是逻辑“0”或“1”输入限制，而不是电源故障限制。储能器处理器单元有一个5ms的内部储能器，足以让CPU进行受控断电。根据EN60529和IEC 529，防护等级为IP20。
Key Features • MPC860 Microprocessor running at 48 MHz. • 16 MB RAM with internal or external battery back-up facility. • 12 x S800 I/O units can be connected to the electrical ModuleBus. • Four on-board communication ports: – CN1 + CN2, Ethernet ports (IEEE 802.3, 10BaseT) – COM3, serial port (RS-232C) with modem support – COM4, serial port (RS-232C) for service tool • Basic communication is extendable by using additional communication interface units. • Redundancy Control Link, for use in redundancy configuration. • Compact Flash interface which supports loading of application and cold retain data storag Memory • 2 MB flash PROM (firmware storage). • 16 MB of SDRAM. Power Dissipation 6 W typical 11 W typical (incl. full supply to ModuleBus and CEXBus, see Appendix B, Power Consumption). Current Consumption 250 mA typical (430 mA max.) (excl. supply of ModuleBus and CEX-Bus, see Appendix B, Power Consumption). Power Input Connector Four pin, screw connector L+, L–, SA and SB. Power Supply Requirements Inputs designated L+ and L– 24 V nominal, variation between 19.2 V DC and 30 V DC. Redundant Power Supply Status Inputs Inputs designated SA, SB • Max input voltage 30 V • Min. input voltage for high level 15 V • Max input voltage for low level 8 V These inputs are status inputs. The threshold levels are logical “0” or “1” input limits, not power fail limits. Power Reservoir The processor unit has an internal 5ms power reservoir, sufficient for the CPU to make a controlled power down. Protection Rating IP20 according to EN60529, IEC 529.
