EMERSON IC693ALG391 2-Channel Series 90-30 Analog Current Output Module

The 2-Channel Analog Current Output module for the Series 90-30 Programmable Logic Controller provides two output channels, each capable of converting 12 bits of binary (digital) data to an analog output for use as required by your application. The Analog Current Output module is capable of providing outputs in the range of 0 to 20 mA. Resolution of the converted signal is 12 bits binary (1 part in 4096). The sign bit is not used in the conversion process. 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. T welve of the bits are used by the D/A converter; the 13th bit (sign) is used to determine if negative data was sent to the module.
