PROTECTION GRADE IP55

CDRX12 PHOTOCELLS are a next generation infrared safety system, particularly suited to the protection of passageways (traffic
and pedestrian) that are fitted with automatic opening and closing systems. The electronic circuit respects the
most up to date standards and regulations and conforms to the standard 3 of the UNI EN 13849-1 (update of the
EN954-1). It is possible to connect up to 3 pairs of photocells and synchronise the transmission (multiplex system).
The necessity of guaranteeing greater ambient noise immunity has led to the evolution of both the transmitter and
receiver cards. The system is based on the criteria “resistance to single failure” that guarantees the maintenance of
safety in case of electrical problems.
The receiver should be installed close to the electronic programmer and wired up drawing its 12/24V power supply
directly from the programmer while the projector can be installed on any surface and doesn’t require wiring. Power
is supplied by a solar panel when light is present and by a 3V lithium battery when insufficient light is available.
The batteries lifespan can be optimised by setting the energy saving function and varying the cut-in time and the
installation distance between the two photoelectric cells.

Technical description CDRX12

Infrared transmission by means of digital modulation of the carrier signal.
Reception via demodulation and decoding of the protocol allowing the transmitter to be identified.
Self locking adjustable lens which can be rotated horizontally through plus or minus 90° and vertically through plus
or minus 30° with respect to the standard installation position.
Double relays on the receiver with digital control increase the security and safety level of the output part (the part
that furnishes the at rest/alarm signal).
Selection of the output contact mode (potential free or resistance 8, 2kΩ contacts).
Differentiated signal LEDS on the receiver indicate the “correct function” status by flashing briefly (every minute) or
the “alarm” status when they remain constantly lit.
Pre-amplified receiver lens.
Reinforced power supply allowing voltages up to 40Vdc or 28Vac.
Overall dimensions 60 x 125 x 41
Maximum range 10m.

CLASS 3 PHOTOCELLS

The circuit board has been produced according to the requirements stipulated by the standards for electronic appliances that fall under category 3 of the EN
ISO 13849-1 (update of the EN954-1). At a practical level it covers the need to guarantee greater immunity to interference in the working environment that is
increasingly being polluted by disturbance. This has led to the technical evolution of both the transmitter part as well as the receiver part based on the criteria
“resistance to single failure” that guarantees the maintenance of the safety level even when faced with electrical problems regarding one or more components within
the device (transmitter or receiver).
