binary inputs module
8 independent voltage inputs
RS-485 / Modbus RTU
LEDs for module operation and Modbus transmission signalling
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 controller. Registers state actualisation occurs only if input signal have fulfil some time restrictions. These restrictions depend on settings of internal digital filter implemented in firmware. Filter allows to eliminate signal oscillations corresponding to contacts bouncing (of mechanical sensors). Filter is factory switched off.
