Alarm Inputs and Relay Outputs
Alarm Inputs
(1-8) Terminal-block-connector port for plugging in terminal block connectors. Supports
up to four input connections (a set of two wires for each) for external relay devices. The
right terminal of the two is a grounded common. For example, fire sensors, PIR, fence
sensors, etc. For more information and channel assignment, see the
External Device Interfaces – ioibox Channel Assignments
(page 22).
Relay Outputs
Terminal-block-connector port for plugging in terminal block connectors. Supports
output of optoisolated signal for up to two connected external relay devices. For
example, an electrical door lock relay.
NO1, NO2 are leads for “NORMALLY OPEN” relay configurations
NC1, NC2 are leads for “NORMALLY CLOSED” relay configurations
C1, C2 are leads for COMMON wire relay configurations for either NC or NO relay. For
more information and channel assignment, see the
section
(page 34) and
External Device Interfaces – ioibox Channel Assignments
(page 22).

Protective Earth Terminal
ioibox must have the external protective earth terminal permanently connected to
protective earth according to local regulations and codes. For more information, see
Connecting the External Protective Earth Terminal
(page 46).
External devices interfaces – ioibox Channel Assignments
The interfaces to external devices (Relay Outputs and Alarm Inputs) are configured using the
ioimage HTML Edition Setup and are distributed between the Channels of the ioibox unit. In order
to configure the external interfaces you will need to know where it is connected on the rear panel
terminal block and which channel it is connected to. In addition, the assignment of each channel to
a respective block IP will be important to note.
The external devices by default are not activated and will not work until they (Relay Outputs and
Alarm Inputs) are configured in the HTML setup.
The following diagrams show the channel assignment for each of the unit models:
