ENCODING PHOTOCELLS

"QCF4"

Wall-mounted encoding photocells, range of up to 15 mt.

The code for the transmitted signal, which must be set at the

time of installation, minimises the possibility of interference

between devices.

ECHNICAL DATA

- Max. range

- TX power supply

- RX power supply

- TX absorption

- RX absorption

- Relay contact capacity

- Operating temperature

- Container

- Protection rating

- Container dimensions

Selecting Operating Code " A " and " B " ( Jumper J2 ) :

The photocell has two operating encoding channels "A" and "B",

in this way it is possible to install 2 pairs of the same model

without any interference between them. Code "A" ( J2 pos. 1-2

"factory configuration" ) and code "B" ( J2 pos. 2-3 ), must be

accordingly selected in the same way, at the time of installation,

: 25 mA Max.

: 1A max at 30 VDC

: -10 ÷ 55 °C

: Polycarbonate

: IP 54

on both the transmitting part (QCF4 TX) and the receiving part

(QCF4 RX).

ESCRIPTION OF THE

Power supply:

The transmitter can be powered with 12 or 24 Volts in either DC

(observing the polarity) or in AC

Connections:

1 – 12/24 Vac-dc

2 – 0V

QCF4 DESCRIPTION OF THE RECEIVER ( RX ):

Power supply:

The receiver can be powered with 12 or 24 Volts in either DC

(observing the polarity) or in AC.

Connections:

1 - 12-24 Vac-Vdc Power Supply

2 - 0 Vac-Vdc Power Supply

3 - NO/NC photocell contact ( J1 selection )

4 - NO/NC photocell contact ( J1 selection )

Selecting the NO/NC Relay Contact ( with Jumper J 1 ) :

With jumper selection J1 it is possible to choose the type of

relay contact as NO (Normally Open) or NC (Normally Closed).

J1 position 1- 2 : NO relay contact.

( TX ) :
