Product Details Supplier Info More products

The TXL2 transmitter and RXL2 receiver modules from Radiometrix are half-duplex multi-channel OEM radio modems offered in the company’s SIL standard footprint.

Operating in the European license-free 433MHz ISM (Industrial Scientific and Medical) frequency band, with a choice of five user-programmed channels, these products can be employed to form transparent one-way radio data links supporting data rates of 9,600bps over a line-of-sight range of 500m (typical).

Unlike raw FM radio module alternatives, these modules are said to take care of preamble, synchronisation, bit balancing, error checking and noise squelching, as well as all transmit timing, valid data identification and datastream buffering activities.

This allows a data link to be set up with the minimum of engineering effort.

Each module can be assigned one to eight unique addresses, so that a multiple radio link network can be established, provided no two modules are attempting to transmit at the same time on the same channel.

The transmitter has an output power of 10dBm (10mW), while the receiver has a sensitivity of -107dBm.

The modules require a 5V power supply, drawing 28mA for transmitting and 22mA for receiving.

They have an operating temperature range of -20C to +70C.

Both the transmitter and receiver comply with EN 300 220-2 and EN 301 489-3 standards.

Applications for these modules include handheld/portable terminals, industrial/commercial telemetry systems, data loggers, and in-building environmental monitoring systems.
