E - Technical specifications
– In order to improve its products, Nice S.p.a. reserves the right to change the
technical specifications at any time and without notice, nevertheless guaran-
teeing the original functionality and intended use.
– All technical specifications refer to a temperature of 20 °C.
IRW relay radio interface
• Type: device installed in the fixed part of the automation and wired to the unit,
used for wireless reception of the status of a sensor with a sensitive edge and
constant resistance or photo-optical technology, installed in the moving part
of the automation.
• Technology adopted: receipt and transmission of data via radio at 868
MHz; 2 isolated contacts for the activation of the safety intervention.
• Power supply: 7-24 VAC/DC; limits: 7-35 VDC; 7-28 VAC 50/60 Hz; with an
isolation transformer compliant with EN 61558.
• Power consumption: 0.65 W
• Phototest input voltage: see "Power Supply" parameter
• Usable radio range: 20m(*)
• Maximum radio range (in ideal conditions): 40m
• "Alt" output NC contact (modifiable with 8.2 kohm constant resistance)
• "Alt 1" output: NC contact
• "Alt" output response time: 1.5 s
• "Alt 1" output response time: <30 ms
• Fault tolerance category: 2, according to EN 13849-1, only if the control unit
in which it is installed can guarantee this category to the whole automation.
• Output relay contact capacity: maximum of 0.5A and 48 VAC (resistive
load: cos fi = 1).
• Output relay contact duration: mechanical life > 1,000,000 cycles; electri-
cal life > 200,000 cycles (resistive load: 0.25 A; 24 VDC)
• Use in acidic, saline or potentially explosive atmosphere: no
• Assembly: inside automatisms or only inside suitable protective containers.
• Container protection rating: IP30
• Operating temperature: -20 to +70°C
• Dimensions (mm): 18 x 33 x 40
• Weight (g): 25
• Maximum number of manoeuvre cycles per day: 15(**), with manoeuvres
lasting up to 1 minute.
Note:
(*) - The range of the transceiver devices may be affected by other devices
operating in the vicinity at the same frequency (such as radio headphones,
alarm systems etc.), causing interference in the system. In the event of
significant interference, the manufacturer cannot provide any guarantee as
to the actual range of its radio devices.
(**) - If the IRW interface is coupled to a TCW1/2 sensor with a photo-optical
sensitive edge, the maximum number of manoeuvre cycles per day will be
less than as stated, in relation to the duration of the manoeuvre. If the IRW
interface is combined with a TCW1/2 sensor with resistive edge, the bat-
tery life does not depend on the number of cycles, which can be performed
as often as desired.
TCW2/TCW1 radio sensor for sensitive edge
For the technical specification of the two devices, refer to the instruction manual.
