Alarm Relay Outputs (RL-4)
• Alarms can be used to control (fire) annunciating devices or signal inputs to other control
devices.
• Four Form C, Single Pole Double Throw (SPDT), 5 Amp relay contacts each assigned specifically
to one alarm.
• Uses RS-485 Modbus™ RTU protocol to communicate the outputs and must have a unique
Modbus™ address set between 80 and 8Fh.
• The X40 controller is configured with a maximum of eight separate relay banks each holding
up to two RL-4 modules.
• Anytime a specific alarm (e.g. Alarm 3) is fired for a particular module in a bank (e.g. Bank2),
all corresponding alarms (e.g. Alarm 3’s) for all modules in that particular bank (e.g. Bank2)
are also triggered.
RS-485 Serial Gas Sensors (Modbus™)
RS-485 Serial gas sensors can be interfaced directly with the X40 controller without the use of I/O modules
by connecting the sensors in a series to the primary RS-485 Modbus™ interface (RS-485 Master Port).
1.6 Enclosure Types
The X40 controller is available in three enclosure types to accommodate various customer needs and
configurations. The number of I/O modules varies depending on the enclosure type and configuration.
N1P Enclosure
The Model X40-32-N1P controller is housed in a NEMA 1 panel mount enclosure for indoor use. The
internal power supply of the N1P controller converts 100-120/220-240VAC to 24VDC and can power a
maximum of 32 sensors and associated I/O modules. A maximum of two I/O modules can be installed on
the outside of the controller. Additional modules must be mounted separately by the customer.
The power supply for the N1P is capable of handling AC inputs from 100-120/220-240VAC, 50-60Hz
without degradation. The X40 controller can be powered by an external DC source that meets the input
requirements (11.5-30VDC) of the unit if AC power is not preferred or available. DC power can be used
for primary or back-up power in the event of an AC power failure. RS-485 and power out are provided for
connection to sensors attached to the unit.
N4X Enclosure
The X40 controller is available in two different size models for the N4X enclosure type. Both the X40-08-
N4X and X40-32-N4X controllers are housed in a NEMA 4X water/corrosion proof enclosure for
indoor/outdoor use. The power supplies for both enclosure types are capable of handling AC inputs from
100-120/220-240VAC, 50-60Hz without degradation. The X40-N4X can be powered by an external DC
source that meets the input requirements (11.5-30VDC) of the X40 if AC power is not preferred or
available. This input can be used for primary power or back-up power in the event of an AC power failure.
The DC output voltage is capable of delivering a maximum of 2 Amps of current to the sensors attached to
the X40 controller.
RS-485 master port and power out are provided for connection to serial sensors attached to the unit.
The X40-08-N4X enclosure houses a maximum of six I/O modules inside of the controller and is capable
of communicating with a maximum of 32 devices. The enclosure can incorporate integral alarms such as
an 8" strobe mounted on the top of the enclosure, horn, or both.
The X40-32-N4X enclosure houses a maximum of twelve I/O modules inside of the controller and
communicates with up to 32 devices.
