This analogue input unit from Siemens is an additional module for your PLC (programmable logic controller). It assists in transferring data between a CPU (central processing unit) and process control equipment. As it comes with four inputs, you can connect it to a PLC and a power supply, as well as to secondary devices. Analogue function means the module receives signals with a varying value as opposed to the static value of digital alternatives. Thanks to 0.05% repeat accuracy in a steady state, you can be sure the unit will provide you with precise data transfer.
