Universal Analog Input Module - 621-0020

Description

Universal Analog Input Module Model No :- 621-0020 Input Voltage :- 30 VAC/DC Universal Analog Input - 16 Inputs ISSC 600 System Z208520400193The model 621-0020 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.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.
