The Solution
We, D'Mark Technologies, offers our solutions from Phoenix Contact networkable components from ‘AUTOMATION', one of six business product division.

Phoenix Contact's compact controller ILC 150 ETH is the heart of the whole control system. ILC 150 ETH was endorsed in this upgrading project is due to its hardware compactness and product reliability from many proven past project records.

Phoenix Contact ILC 150 ETH controller was linked to HMI screen via ethernet port. Phoenix Contact InLine I/O modules were adopted for I/O expansion in controlling ECS equipment such as their Evaporator Unit Air-con(PEU), intake and exhaust fans control etc. The robust industrial grade type of unmanaged switches from Phoenix Contact Factory Line SFN series were used to provide networking connectivity.
