Module type SIN-8 allows to monitor 8 binary voltage inputs via the RS-485 connection. It finds application in distributed control and visualization systems. Standard Modbus protocol transmission functions make device registers (address, state of inputs, device ID). All SIN-8 operating functions, available via the RS-485, can be implemented with any typical visualization software or, for instance, with a suitably MultiCon CMC-99 controller.
