Analog input modules use an A/D converter to convert sensor
voltage, current, thermocouple or RTD signals into digital data. The
digital data is then translated into engineering units. When prompted
by the host computer, the data is sent through a standard RS-485
interface. The analog input modules protect your equipment from
ground loops and power surges by providing opto-isolation of the A/
D input and transformer based isolation up to 3,000 V
The ADAM-5013 is a 16-bit, 3-channel RTD input module that features
programmable input ranges on all channels. This module is an extreme-
ly cost-effective solution for industrial measurement and monitoring
applications. Its opto-isolated inputs provide 3,000 V
between the analog input and the module, protecting the module and
peripherals from damage due to high input line voltage.
Note: Owing to the conversion time required by the A/D
converter, the initialization time of each ADAM-5013
module is 5 seconds. Thus the total initialization
time will be about 20 seconds if all 4 I/O slots in an
ADAM-5510 main unit contain ADAM-5013 modules.
