8CWA & 16CWA

8CWA or 16CWA is an alarm central and an ideal solution for small and medium-sized gas alarm systems based on 4-20mA signals. Each channel has three free programmable alarm levels – Alarm 1, Alarm 2 and warning. IP65 classification makes it possible to place the unit in rugged environments. With the RS-485 output it enables connection to monitoring systems such as SIMS-NX.
