to avoid damage to assets. Please read this manual before installing and commissioning
the device and keep the manual in an accessible location for all users.
Contains FCC ID: W70MRF24J40MDME
Caution: To satisfy FCC RF Exposure requirements for mobile and base station
transmission devices, a separation distance of 20cm or more should be maintained
between the antenna of this device and persons during operation. To ensure compliance
operation at closer than this distance is not recommended. The antenna used for this
transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter. No other antenna may be used with this equipment other than the PCB
antenna supplied with this equipment.
Please see the Certifications section for more information on RF Exposure Compliance
1.2 Hardware Features
The IWTxT Wireless 4-20 mA Transmitters has been designed to provide an excitation
voltage to any standard 4-20 mA transmitter, take a reading and transmit the value to one
of the IWR range of receivers where the value can be outputted as either a 4-20 mA or
1-5 V dc signal, or to an IWR-PORT or IWR-USB receiver.
The IWR-1 has a single output and the IWR-5 has five outputs, each of which can be
linked to an IWTxT transmitter.
The IWTxT current transformer transmitter works on the license-free 2.4 GHz band.
Ranges of up to 500 m are possible using the standard transmitter and receiver unit with
the optional 3dBi antenna giving a range of up to 750 m.
The transmitter is powered by a 3.6 V lithium cell and care must be taken to insert the
battery in the correct polarity.
