PURPOSE: A remote transmission unit device integrated with a communication unit is provided to minimize switching time of one failure of one remote transmission unit to the other remote transmission unit by duplexing the remote transmission unit. CONSTITUTION: A first remote transmission unit comprises a first CPU module(140a) which is formed in a card shape and a first state input module(110a) which transmits data to the first CPU module. The first remote transmission unit comprises a first control output module(120a) which performs a control command, a first analog input module(130a) which transmits a converted digital value to the first CPU module through a first VME(VERSA module eurocard) Bus, and a first power module(150a). A first communication unit integrated with the remote transmission unit includes the first communications unit which is comprised of a first Ethernet switch communication module(160a). The integrated remote transmission unit comprises a second remote transmission unit and a second communication unit. |
