Fanuc IC693ALG391 PLC

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.
