The DI803 is an 8 channel 230 V a.c./d.c.digital input module for the

S800 I/O. This module has 8 digital inputs. The a.c. input voltage

range is 164 – 264 volt and the input current is 7.6 mA at 230 V a.c.

The d.c. input range is 175 – 275 V and the input current is 1.6 mA at

220 V. The inputs are individualy isolated. Every input channel

consists of current limiting components, EMC protection

components, input state indication LED and optical isolation barrier.
