Analog Input Module Capacity for Foxtrot 2 PLC

There is no limit for amount of analog modules on TCL2. The only limit is 10 IO modules on one TCL2 interface. Because analog module IT-1604 is equipped with 8 analog inputs, for 160 analog inputs you will need 2 fully occupied TCL2 buses. One on CP-2090 interface, second one on an additional SE-0140 sub-module inserted to CP-2090's slot. These modules have multiplexed inputs. The sample transfer time for one input is 65 ms, the sample repetition time is therefore 500 ms. However, the communication between the analog module and the central module runs independently of the input measurement, the state of the internal registers is continuously transmitted.
