DIU 230
Power over Ethernet Door Interface Unit
• Door and reader power with
Ethernet communications via
a single Cat 5e/6 cable
Where a high level of security is required and cabling must be kept to a minimum,
the PoE+ DIU 230 offers the ideal solution. Used as part of the AC2000 security
management system, the DIU 230 is a complete package that combines Ethernet
communication with battery backed lock and door power.
• Eliminates the need to have
mains power and a power supply
at the door
The DIU 230 works in conjunction with a Midspan power injector between the server
and the door. Using just a single Cat 5e/6 cable the DIU 230 eliminates the need for
a mains power supply at the door. Where local power is not readily available, the
DIU 230 can offer significant cost savings.
• Provides local power for a full
door set including up to 2
The DIU 230 supports a range of PoE+ mid-spans, offering the highest levels of
flexibility, with sufficient power for almost every situation.

Product Highlights
Power Over Ethernet Access Control
The DIU 230 offers a complete IP based
access control solution that eradicates
the need to provide local mains power at
the door. The unit installation is classed
as low voltage and can be completed by
IT network installers without the expense
of an electrician or electrical contractor.
The DIU 230 has an increased current
capacity of up to 2 Amps, Midspan
dependant. This allows a wide range
of door locks or a pair of locks and
end devices to be used. For 2 Amp
requirement the Phihong 36 Watt model
of Midspan is advised.
The unit incorporates a wiegand interface
which allows a 3rd party weigand read
head to be directly connected. This
provides a low cost alternative if an LCD
and keypad are not required for the exit
side of the door.
Available as a board only version or as
lockable wall mounted enclosure with
storage for back up battery.
When fitted with a back-up battery, the
DIU 230 and any equipment attached to
it will continue to work through a power
failure. For example, a 7.2AH battery
could keep a door operational for up to
4 hours.
