DN003 Description

The DN003 DeviceNetTM Discrete Input Module provides a total of 16 inputs. These are well suited to monitor discrete inputs in a harsh mobile environment. The inputs have extensive protection circuitry to provide tolerance to electrical transients. Three of the sixteen inputs may be individually configured as frequency counters or pulse accumulators. 
System-wide fail-to-safe design is facilitated by the ability to individually configure the hardware to either "pull-high" or "pull-low" in response to an unconnected input.
