IS200EPSMG1ABB燃机模块,IS200EPSMG1ABB使用方法
如果CPU进入停止模式或重置，模块的状态可以默认为0/4mA或保持最后状态。通过配置DEF0/4跳线来选择所需状态在模块上的可拆卸端子板连接器上。如果未安装跨接导线，则如果连接了备用用户电源，输出将在停止或重置时保持最后状态当系统电源下降时。如果存在DEF0/4跳线，则模块默认为4 mA停止或重置时，在4至20 mA范围内或在0至20 mA范围内为0 mA。每个跳线一个模块用于对保持最后状态或DEF0/4的两个输出进行编程。
IS200EPSMG1ABB燃机模块每个模块输出可用作电流源或精度较低的电压源。A.电压在对应于电流输出的VOUTx处输出。选择电流或电压输出通过输入/输出端子板上的跨接线实现。如果未安装跳线，则模块用作电流源。如果存在JMPVx跳线，则模块将作为电压源。每个通道都可以选择电压或电流。设置电流输出范围决定电压范围。电压范围可以通过使用250欧姆电阻器代替JMPVx到IOUTx的电压跳线。下表显示范围设置和电压输出之间的关系。模块的主要电源是由PLC提供的隔离+24 VDC电源电源。模块的输入/输出端子板上还为用户提供了两个端子供电+24伏。这允许您提供备用电源，以便输出可以如果内部电源丢失并且选择了保持最后状态，则继续保持其值。你可以还需要提供模块电压，以减少PLC隔离+24 VDC电源上的负载供给当施加的电压高于隔离的+24 VDC时，将使用用户电源电源电压范围为21.5伏至26.5伏。模块中产生约+24V的内部电压源，以驱动电流回路输出。模块上的电流环路驱动器是源类型驱动器。这意味着电流从电流回路输出中流出，以便用户的负载可以返回到公共。A.电阻器和公共回路串联，以限制接地回路电流。
The state of the module if the CPU goes to the STOP mode or RESET, can be either Default to 0/4
mA or Hold-Last-State. Selection of the desired state is made by configuring the DEF0/4 jumper
on the detachable terminal board connector on the module. If the jumper is not installed, the
outputs will Hold-Last-State on STOP or RESET provided that a backup user supply is connected
when the system power goes down. If the DEF0/4 jumper is present, the module defaults to 4 mA
on the 4 to 20 mA range or 0 mA on the 0 to 20 mA range on STOP or RESET. One jumper per
module is used to program both outputs for Hold-Last-State or DEF0/4.
Each module output may be used as a current source or as a less accurate voltage source. A
voltage is output at VOUTx that corresponds to the current output. The selection of current or
voltage output is made with a jumper on the I/O terminal board. If no jumper is installed, the
module performs as a current source. If the JMPVx jumper is present, the module performs as a
voltage source. Each channel has the option of selecting voltage or current. The setting of the
current output range determines the voltage range. The voltage range can be increased by using a
250 ohm resistor in place of the voltage jumper from JMPVx to IOUTx. The following table shows
the relationship between range settings and voltage outputs.The primary power source for the module is the isolated +24 VDC power supplied by the PLC
power supply. Two terminals are also provided on the module’s I/O terminal board for user
supplied +24 volts. This allows you to provide a standby power supply so that the outputs can
continue to hold their value if the internal supply is lost and Hold-Last-State is selected. You may
also want to supply the module voltage to reduce the load on the PLC isolated +24 VDC power
