DA-500 series

详情

DA***0 detects various combustible & toxic gases leaked from industrial areas for gas producers, gas users, gas reservoirs, gas by-producers, and so on, in order to prevent any accidents in advance. DA***0 converts digital signal into the ***0mA standard current output signal which can be transmitted to various devices such as PLC, DDC, or recorder to build comprehensive gas monitoring system. Also, DA***0 provides RS***5 communication signal and alarm relay contact. DC ***0mA standard output signal realizes max ***0m long distance output signal transmission and RS***5 communication signal realizes max ***0m long distance signal transmission.
