Product Description：
The IC697ALG440 Current Input Expander Module belongs to the Series 90-70 Programmable Logic Controllers product line manufactured by GE Fanuc. It has 16 current inputs with a 4 to 20 milliamps input current range. The IC697ALG440 Current Input Expander Module must be used with a base converter module and a voltage expander module to create an analog input subsystem for a programmable logic controller. The users can use any mix of these expander modules with the base converter to have a system with a maximum of 120 input channels. It converts a digital form of a signal into an analog form and represents the converted data in the 2’s complement format. Some of the features of the expander module include status indicator LEDs, error detection facilities, expander channel response detection, and module health diagnostic facilities.
