The system acquires up to 14 discrete and 20 universal/HART analog inputs from process sensors, displays sensor data on its 7-inch multicolor TFT screen, records the data internally, performs math calculations and alarm checks, and transmits the data to a PC or any control system via Ethernet, RS-232/485, Modbus, Profibus DP or PROFINET digital communication links. Data can also be stored to a device plugged into the USB or the SD port. Inputs to the system include 4-20 mA, 4-20 mA with HART, voltage, RTD, thermocouple, pulse, frequency and current. The base unit can accommodate up to 14 discrete inputs, two analog outputs and 12 relay outputs. Up to five I/O cards can be added to the base unit, allowing up to 20 universal/HART analog inputs. Data is stored in tamper-proof internal memory, on an SD card or on a USB stick - all of which fulfill the security requirements of FDA 21 CFR part 11. An integrated web server allows browser-based access to the unit via laptops, PCs, smartphones, tablets, handheld maintenance devices and remote systems. The built-in Advanced Data Manager includes packages for mathematics, alarm functions, batch management, wastewater + RSB (rain spillway basin) applications, and energy calculations.
