The number of channels in the IC693ALG222 may be single ended (1 to 16 channel) or differential (1 to 8 channel). The power requirement for this module is 112mA from 5V bus, and also it requires 41V from 24V DC supply to power the converters. The two LED indicators indicate the status of user power supply the module’ status. These two LEDs are MODULE OK, which gives the status regarding power-up, and POWER SUPPLY OK, which checks whether the supply is above the minimum required level. The IC693ALG222 module is configured either using logic master programming software or via Handheld programming. If the user chooses to program the module via Handheld programming, he can only edit active channels, not active scanned channels. This module uses the %AI data table to record analog signals for the use of the programmable logic controller.
