These new modules provide connection of 24V and 120V inputs in a format that is not channel-channel isolated. This format can save some wiring time in applications that can use it, since a common return is used for each group of 8 channels.

Features of these modules include:
  • Single-wide modules, supporting 16 inputs
  • Channel On/Off status indication
  • Supports hot-swapping
