This DI811  module has 16 digital inputs. The DI811 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 DI811 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.
