MTH DCS WIFI control system panel wiring scheme
The attached photos show a modular MTH DCS WIFI control system panel wiring scheme that provides for various cable interconnections between the units. All interconnected cables including power connections are placed in a 4 inch wide wireway. This system places all wiring underneath the various DCS system units in a "trough". This system can also be easily expanded to provide additional AIU units that are also mounted on a separate panel. All the DCS components are securely fastened to the various panels and are mounted "above" the wireway. Not shown are additional circuit breaker protection panels. Most control system panels as shown are 12 inches wide by 24 inches in length.
The system uses Passive Mode control so that no connections to the TIU inputs are needed. The TIU is provided with AUX POWER from a brick as shown.
