UNii expander without power supply in housing

The UNii I/O+ module allows you to expand the UNiio alarm control panel with additional wired inputs and outputs. The module is supplied in a metal housing without its own power supply and must be powered via RS-485. The device provides 8 wired inputs and 2 outputs (2 open collector outputs, max. 200mA). The module can be optionally expanded with another 8 wired inputs. A fully expanded device will allow the control panel to be expanded to 16 line inputs.
