Technical specification
Outputs: | 4 x analog output 4 – 20 mA (gas concentration, process transmission, 2 x AUX) – easy user selection via DIP switch between active/passive mode |
8 x digital output (NAMUR) | |
Inputs: | 4 x analog input 4 – 20 mA (process temperature and pressure) – easy user selection via DIP switch between active/passive mode |
1 x RTD (PT100/PT1000) - easy user selection via DIP switch between PT100/PT1000 and 2-/3-/4-wires | |
8 x digital input | |
Local User Interface: | Human Machine Interface (HMI) - LCD backlight display located on the transmitter housing lid |
Ethernet port: a) WebServer – system configuration and data acquisition via web browser, b) Windows based program – GasEye logger for real-time data acquisition, c) remote service and diagnostics |
|
Optional: | Modbus (TCP/IP), Modbus RTU, Profinet, Profibus |
Power input: | 24 VDC nominal (19 – 30 VDC) |
Power consumption: | < 15VA (< 25VA if ATEX) |
Automatic gain control (AGC): | AGC ensures correct gas measurement even at high dust loads resulting in loss of optical transmission down to 0.5%. AGC operates fully automatic with no need for manual adjustment of the signal gain under any process conditions. |
Self-calibration features: | Internal reference gas compartment is used for closed loop control of the zero and span drift |
