DI818

This module has 32 digital inputs. The input voltage range is 18 to 30 volt d.c. and the input current is 4.3mA at 24 V. The inputs are divided into two individually isolated groups with 16 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

  • 32 channels for 24 V d.c. inputs with current sinking
  • Two Isolated groups of 16 channels with voltage supervision
  • Voltage Supervision
  • Signal Filtering
