The new 8CWA and 16CWA alarm units are an ideal solution for small and medium sized gas detection systems. The IP65 rated units provide 24 and 16 free programmable relay contacts and they can be connected to a SIMS-NX bus line.
When implementing larger systems a profibus-DP network with TX-WAD / SH-WAD detectors in combination with a PLC based alarm system provide a flexible and cost effective solution.
