Product Overview

Weidmuller industrial wireless products provide secure and

reliable solutions for a wide range of industries and applications,

as an alternative for signal and data wiring. These products fall

into four groups:

Wireless I/O, also known as radio telemetry, connect directly

to sensor and control signals, and transmit the signal values by

radio. The signals are either re-created as similar signals, or out-

put as a data connection — Ethernet, Profibus, Modbus etc.

Wireless I/O networks can be as simple as two units transferring

a small number of signals from one point to another, or they can

be complex data-acquisition networks with multiple “master”

interfaces to external systems.

Wireless Gateways provide wireless connectivity between

data buses - connectivity between devices using the same

data bus, or between different data buses (Ethernet to Profibus

to DeviceNet to Modbus etc). Wireless gateways are similar in

operation to wireless modems, however gateways only provide

a register interface to the data bus, transferring I/O registers only.

Wireless Modems transmit serial or Ethernet data, providing

a wireless extension of the data link. Example applications are

PLC to PLC connections (point-to-point), connecting SCADA

to a group of PLCs (point-to-multipoint), or forming a wireless

PLC LAN (multidrop). Wireless modems transmit the data with

minimal transformation.

Wireless GPRS Alarm Modems use GPM mobile technology

to provide alarm and status information directly to a mobile

device, SMS, email, or via fax. The GPRS Alarm Modem can

be located anywhere GSM reception is available. Site, remote

location, or plant monitoring can be conducted remotely without

the need for onsite employees.
