Product Manual Excerpt

Analog Voltage Output - 2 Channel IC693ALG390 The 2-Channel Analog Voltage Output module for the Series 90-30 Programmable Logic Controller provides two output channels, each capable of converting 13 bits of binary (digital) data to an analog output for use as required by your application. The Analog Voltage Output module is capable of providing outputs in the range of 10 to +10 volts. Resolution of the converted signal is 12 bits binary plus sign which is effectively 13 bits (1 part in 8192). Both channels are updated on every scan (about 5 milliseconds). User data in the %AQ registers is in a 16-bit 2 s complement format. The 13 most significant bits from the %AQ register are converted to sign magnitude by the PLC and sent to the module for use by the D/A converter circuitry. The placement of the 13 bits converted to sign magnitude is shown below. The relationship between the voltage output and the data from the D/A converter is shown in Figure 3-30.

D/A Bits vs. Voltage Output The state of the module, if the CPU goes to the STOP mode or RESET, can be either Default to 0 volts or Hold-Last-State. Selection of the desired state is made by configuring the DEF0 jumper on the detachable terminal connector on the module. If the jumper is not installed, the outputs will Hold-Last-State on STOP or RESET. Scaling of the output is shown below. 11 11-2 Series 90-30 PLC I/O Module Specifications July 2000 GFK-0898F %AQ (decimal) VOLTAGE (V) 0 a44658 10 10 32000 32000 0 Figure 11-2. Scaling for Voltage Output The primary power source for the module is the isolated +24 VDC power supplied by the PLC power supply. Two terminals are provided on the module s terminal connector 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. Additionally, you can also supply the module voltage to reduce the load on the PLC isolated +24 VDC power supply. The user supply must be used when the applied voltage is 0.7 volts higher than the isolated +24 VDC 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 noise, all field connections should be wired using a good grade of twisted, shielded instrumentation cable. The shields should be connected to GND on the user terminal connector block. The GND connection provides access to the baseplate (frame ground) resulting in superior rejection of noise caused by any shield drain currents. The module provides electrical isolation of externally generated noise 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 Analog Voltage Output modules that can be installed in a system. Table 11-1. Specifications for Analog Voltage Output Module, IC693ALG390 Voltage Range 10 to +10 volts Calibration Factory calibrated to 2.5 mV per count Supply Voltage (nominal) +24 VDC, from isolated +24 VDC on backplane or user supplied voltage source, and +5 VDC from backplane External Supply Voltage Range 18 to 30 VDC External Supply Voltage Ripple 10% Update Rate 5 msec (both channels) This update rate is approximate since it is determined by I/O scan time, and is application dependent. Resolution 2.5 mV (1 LSB = 2.5 mV) Absolute Accuracy 5 mV at 25 C (77 F) Offset 1 mv maximum, 0 to 60 C (32 to 140 F) Output Loading (maximum) 5 mA (2K ohms minimum resistance) Output Load Capacitance 2000 pico farads, maximum Isolation 1500 volts between field side and logic side Internal Power Consumption 32 mA from +5 volt supply 120 mA from +24 volt supply (isolated backplane or user supply) Refer to Appendix B for product standards and general specifications. In the presence of severe RF interference (IEC 801-3, 10V/m), accuracy may be degraded to 50mV.
