Universal Analog Input - 16 Inputs

The model 621-0020R Universal Analog Input Module (UAIM) allows you to obtain data from a maximum of 16 analog input sources. It contains an Analog-to-Digital Converter (ADC) that changes the analog signals into binary counts.

The 'R' suffix indicates the module can be removed or inserted into an I/O rack while the rack remains powered. Other I/O modules in the rack continue to control the machine or process.

The 'C' suffix indicates models that conform to CE directives 73/23IEEC, the low voltage directive, and 89/336IEEC, the EMC directive.

An analog input module accepts analog signals from field devices connected to the module's terminals and converts the signal data to 12-bit binary values (0 to 4095) via an analog-to-digital converter contained in the module's circuitry. The digital values are stored in a holding register in the module and can be accessed by the Logic Manager control processor via a PULL instruction.
