BUILT – IN ENCODING PHOTOCELLS “ IR/IT 2126 NEW “
Built-in encoding photocells, range of up to 30 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 : 30 metres
- TX power supply : 12-24V AC-DC
- RX power supply : 12-24V AC-DC
- TX absorption : 10 mA Max.
- RX absorption : 25 mA Max.
- Relay contact capacity : 1A max at 30 VDC
- Operating temperature : -10
÷
55 °C
- Container : Polycarbonate
- Protection rating : IP 54
Selecting Operating Code “ A ” and “ B “ ( Jumper J1 ) :
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" ( J1 pos. 1-2 “factory configuration” ) or code “B” ( J1 pos. 2-3 ), must be
accordingly selected in the same way, at the time of installation, on both the transmitting part ( IT 2126 NEW ) and the
receiving part ( IR 2126 NEW ).
