GENERAL DESCRIPTION
Based on a microcontroller and equipped with a
short circuit isolator, the IO500 IN OUT module is
a programmable device which can be configured
as follows:
actuator output module (MU)
input module for latched dry contacts (LI)
input module for pulsed dry contacts (PI)
Also, optional functions relevant to the selected
operating mode can be enabled. The module can
be programmed directly through the Elkron FAP
series control panels.
Factory configuration of the multi-purpose
module is set as actuator in mode 0.
The
IO500
is able to store automatically, into its
non volatile memory, thirty measures before and
thirty measures after the alarm condition.
These measures can be shown in graphic or text
mode on the display of the control panel.
This feature is very important to analyse what has
happened before and after the detected alarm
condition.
The
IO500
is equipped with dry contact relay
output, supervised output and external power
supply input.
When an external power supply is connected to
the module, the supervised output max current is
0.75A@30V
⎓
, if no external power supply the
supervised output works as an alarm repetition
output with a current is limited to 15 mA@18V
⎓
.
The bi-coloured LED (green-red) indicates the
module condition in normal operating mode; on
the other hand, when in service mode, it can be
used to show the detector’s address by means of
a special function activated from the control
panel.
For further information, please refer to the
programming manual of the FAP series control
panel.
IO500 Actuator module
The following four operating modes are available:
Mode 0
This operating mode will be used to activate an
equipment connected to the actuator and, once
activated, perform one or more deactivations and
reactivations by operating locally: in this case, a NO
contact of the equipment must be connected in
parallel with the input 1 end-of-line resistor (Fig. 1).
Externally powered module
In idle condition, the actuator checks the presence
of the 10K
end-of-line resistor at input 1; if the
input is opened or short-circuited, the module
signals respectively fault n° 13 or n° 12 to the
control panel.
When activated via a command sent by the control
panel, the actuator activates both the relay and the
supervised output; input 1 can be used to locally
deactivate the actuator by closing a NO contact in
parallel with the end-of-line resistor. Deactivation
is held as long as the contact is closed (Fig. 1).
Block and un-block of the actuation lead
respectively to signalling of faults n° 100 and n°
101 to the control panel.
Externally un-powered module
Input 1 is not checked and the supervised output
works as an alarm repetition output.
Mode 1
This operating mode will be used to activate an
equipment connected to the actuator: in this case,
an NC contact of the equipment must be
connected in series with the end-of-line resistor of
the input 1 (Fig. 2).
Externally powered module
In idle condition, the actuator checks the presence
of the 10K
end-of-line resistor at input 1 and if
the input is opened or short-circuited the module
signals respectively fault n° 13 or n° 12 to the
control panel.
When activated, the actuator checks input 1 as in
idle condition and activates the relay and
supervised output.
Externally un-powered module
The actuator behaves as in the externally powered
module, the only difference being that the
supervised output works as an alarm repetition
output.
