I/O SYSTEMS – S800 I/O – DI811

This module has 16 digital inputs. The input signal voltage range is 36 to 60 volt d.c. and the input current is 4 mA at 48 V. The inputs are divided into two individually isolated groups with eight channels and one voltage supervision input in each group. Every input channel consists of current limiting components, EMC protection components, input state indication LED and optical isolation barrier. The process voltage supervision input give channel error signals if the voltage disappears. The error signal can be read via the ModuleBus. 

Features and Benefits

  • 16 channels for 48 V d.c. inputs with current sinking
  • 2 isolated groups of 8 with voltage supervision
  • Input status indicators
