Text for tenders: Wireless I/O Unit


Wireless I/O Unit

The wireless I/O unit forms the basis of the Rittal

wireless sensor network. For operating purposes,

the unit must be cabled to Processing Unit II

(PU II) DK 7320.100, either using the connection

cables for sensor units or a Cat 5 cable (max.

50 m). Data exchange and power supply to the

wireless I/O unit occurs via this connection. Up

to 4 wireless I/O units may be connected to one

PU II.

The wireless I/O unit has an aerial attached to the

enclosure which may be directed according to the

installation position. This aerial may optionally be

replaced with an external version. The external

aerial is available separately as an accessory.

The system is attached via the 1 U mounting unit

or the individual mounting unit.

A wireless I/O unit is capable of managing up to

16 wireless sensors. There is a choice of 4 different

sensor types. These are also available as

accessories. The sensors may be used in any

given combination.

Sensors are commissioned in teach mode on the

base station, and using the teach key on the

sensor. The wireless measurement system should

be used to determine adequate radio connection

quality.

Option for a wider reception range:

If the radio range of the wireless I/O unit connected

to the PU II is not adequate, additional

wireless I/O units may be used as repeaters (up

to a maximum of 5 repeaters). These I/O units

used as repeaters do not require any further cable

connection to the PU II, but merely need to be

supplied with power via a separate power pack

with country-specific connection cables. The

repeaters must be installed in the base station,

where they occupy one of the 16 sensor slots.

There is no need to teach the sensors into the

repeaters.

Technical specifications:

Range in rooms with visual connection:

up to 50 m1)

Range in open spaces with visual connection:

up to 200 m1)

Rated voltage: 24 V DC

1 port RJ 45 for the PU II

16 wireless access points for Rittal wireless sensors,

or alternatively up to 5 repeaters and up to

11 sensors.

Protection category: IP 40 to EN 60 529

Temperature range: +5°C to +45°C

1) If the ranges are not adequate, they may be

extended with the wireless I/O unit as repeater

or with the external aerial. The range information

depends on the conditions of use and may vary

according to the application.
