420 SERIES
- Simple, accurate controllers enabling continuous measurement and observation of the measured function and temperature results.
- Waterproof housing.
- Back-lit display makes working easier.
- Two relays enable controlling of external devices, for example valves etc.
- Instead of relays a current loop (0-20 or 4-20 mA)or a PC output possible.
- Power source – 12V power adapter.
- The 801 controller enables measurement and controlling in 1 point (1 channel) and the 804 model in 4 measuring points (4 channel).
- Large graphic display with results and additional information.
- Outputs: relays (alarm and PID regulation).
- Isolated digital output: RS-485, MODBUS (ASCII and RTU).
- Isolated current output (loop): 0 to 20 or 4 to 20 mA.
- Powered with 230V, galvanically separated from the input clamps.
- Wide range of optional power voltage: 110/230/24V AC, 12 - 24V, signalisation of low power source level.
