The distributed remote IO system consists of a network adapter module (CTL ECT/CTL PN) and an extended I/O module (DIT/DQT).COTRUST CTL series network adapter module is responsible for fieldbus communication(EtherCAT/Profinet)。And realize the communication connection with the master station controller or the host computer software；Network adapters and extended I/O modules can be freely combined according to field requirements. In practical application, The preferred use of distributed I/O modules can reduce the cost, in the case of more bit requirements.
