General Description

The EV-2I1O (-EU) Dual Input / Single Output Module is an addressable input/output
module with short circuit isolator. The module provides two supervised inputs (Class B) and
one dry contact relay output rated at 5A@240Vac. The EV-2I1O uses UK 2-gang box with
surface and flush mount options, and the EV-2I1O-EU uses European 503 electrical box
flush-mounted.
Two inputs are monitored to detect normal/input/open/short state, which can be used as
general purpose inputs.
The relay output is used for the control of equipment such as dampers and extractors for
ventilation or smoke control system. The relay contact is monitored to detect the
condition (on /off /relay stuck).
