Analog Current/Voltage Output – 8 Channel IC693ALG392 The 8-Channel Analog Current/Voltage Output module provides up to eight single-ended output channels with current loop outputs or voltage outputs. Each analog output channel is capable of providing two current output ranges or two voltage output ranges. Each channel can be individually configured for the output range required for your application.

The module has no jumpers or switches for configuration. All ranges can be configured using either Logicmaster 90-30/20/Micro or CIMPLICITY Control Programming Software configurator function, or the Series 90-30 Hand-Held Programmer. The default range is 0 to +10 volts. Configurable current and voltage output ranges are: 0 to +10 volts (unipolar) 10 to +10 volts (bipolar) 0 to 20 milliamps 4 to 20 milliamps Each channel is capable of converting 15 to 16 bits (depending on the range selected) of binary (digital) data to an analog output for use as required by your application. All eight channels are updated every 12 milliseconds. User data in the %AQ registers is in a 16-bit 2 s complement format. In current modes, an open-wire fault is reported to the CPU for each channel. The module can go to a known last state when system power is interrupted. As long as user power is applied to the module, each output will maintain its last value, or reset to zero, as determined by how you have configured the module. Important Product Information Please note the following important product information.

This version of the 8-Channel Analog Current/Voltage Output module requires the following product versions for compatibility: CPU: Firmware Versions 3.3 to 4.6: If your CPU has firmware version 3.3 to 4.6, you must select 16 %I bits at configuration. If this selection is not made, a loss of module fault will occur. CPU: Firmware Version 5.0 or later: If your CPU has firmware version 5.0, or later, then the %I configuration will accept 8 or 16 %I bits. Logicmaster 90-30/20/Micro Software: Version 5.00, or later, is required to configure the module using the Logicmaster 90-30/20/Micro software configuration function. Control Software: Version 2.00, or later, is required to configure the module using the Control software configuration function. 11 11-12 Series 90-30 PLC I/O Module Specifications July 2000 GFK-0898F IC693ALG392 Current/Voltage Ranges and Output Modes Current Operation In the 4 to 20 mA range user data is scaled so that 4 mA corresponds to a count of 0 and 20 mA corresponds to a count of 32000. In the 0 to 20 mA range, user data is scaled so that 0 mA corresponds to a count of 0 and 20 mA corresponds to 32000.
