SLI-8

Code: SLI-8
  • multi counters module
  • 8 independent voltage inputs
  • RS-485 / Modbus RTU
  • LEDs for module operation and Modbus transmission signalling

Description

Multi counters module SLI-8 allows to counting of pulses delivered to 8 isolated binary inputs independently. All counters are 24 bit long and can be read and cleared by user at any time. Occurrence of HIGH state on particular input is signalled by green LEDs marked IN1 to IN8. Incrementation of counter occurs after falling edge on particular input (input state changes from HIGH to LOW). It is essential that pulses have fulfill some time restrictions. These restrictions depend on settings of implemented internal digital filter, which allows to eliminate signal oscillations corresponding to contacts bouncing (of mechanical sensors).
