The Alog Voltage module is capable of providing s in the range of –10 to +10 volts. Resolution of the converted sigl is 12 bits biry plus sign which is effectively 13 bits (1 part in 8192). Both s are updated on every scan (about 5 milliseconds). User data in the %AQ registers is in a 16-bit 2’s complement fort. The 13 most significant bits from the %AQ register are converted to sign gnitude by the PLC and sent to the module for use by the D/A converter ry. The placement of the 13 bits converted to sign gnitude is shown below. The relationship between the voltage and the data from the D/A converter is shown in Figure 3-30.

D/A Bits vs. Voltage The state of the module, if the goes to the STOP mode or RESET, can be either Default to 0 volts or Hold-Last-State. Selection of the desired state is de by configuring the DEF0 jumper on the detachable termil connector on the module. If the jumper is t installed, the s will Hold-Last-State on STOP or RESET. Scaling of the is shown below. 11 11-2 Series 90-30 PLC I/O Module Specifications – 2000 GFK-0898F %AQ (decil) VOLTAGE (V) 0 a44658 10 10 32000 32000 0 Figure 11-2. Scaling for Voltage The priry power source for the module is the isolated +24 power supplied by the PLC power supply. Two termils are provided on the module’s termil connector for user supplied +24 volts. This allows you to provide a standby power supply, so that the s can continue to hold their lue if the interl supply is lost and Hold Last State is selected. Additiolly, you can also supply the module voltage to reduce the load on the PLC isolated +24 power supply. The user supply must be used when the applied voltage is 0.7 volts higher than the isolated +24 supply, which can range from 21.5 volts to 26.5 volts. An LED at the top of the module’s faceplate is ON when the module’s power supply is operating. To minimize capacitive loading and ise, all field connections should be d using a good grade of twisted, shielded instrumentation cable. The shields should be connected to GND on the user termil connector block. The GND connection provides access to the baseplate (frame ground) resulting in superior rejection of ise caused by any shield drain currents. The module provides electrical isolation of exterlly generated ise between field wiring and the backplane through the use of optical isolation. This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC system. Refer to page 3-11 to determine the number of Alog Voltage modules that can be installed in a system. Table 11-1.
