PD 951 RFID Reader

In order to meet the demands for real time identification and registration, PROCES-DATA has developed a new electronic RFID Reader module using the latest transponder technology.

The PD 951 is a general purpose LF Dual Band RFID reader.

Application Examples:

Identification of livestock animals.
Building automation / Access control.
Waste management.
Vehicle control.
Warehousing and logistics.
Cargo terminals.
Tracking containers and pallets in the supply chain.

Specific Features

· High performance Dual band RFID Reader 125 kHz / 134.2 kHz.

· Supported Transponder types: ISO 11784 and 11785 (read only), EM 4102

(read only).

· The PD 951 is capable of providing excitation signals to, and receiving and decoding signals from, HDX and FDX-B transponders.

· The module complies with ISO 11784 in terms of a having a 64 bit dataformat, for official registration and identification of – Country code, National farm code, Animal No.

· Read range: 10 – 150 cm.

· Automatic self-tuning for simple and easy installation

– no maintenance or adjustment required.

· Advanced internal self-testing.

· Wide power supply range.

· Very low power consumption.

· Wide temperature range.

Mechanical Details

The PD 951 module is housed in a black plastic case.

The module is designed for plugging directly on to a mounting rail (EN 50 022 / DIN 46277). The module incorporates two snap connectors, which provide the terminals for field connection, power and communications.

The module may be DIN rail mounted for a panel mounted configuration and contained in a sealed box designed for the plant environment. It may be removed for service, without interfering with operational activities on the rest of the network.

*Dimensions*	(WxHxD)	130.0 x 112.0 x 50.9 mm
Case material		Black NORYL GFN ( injection moulded )
Front foil		Polycarbonate
Back plate		Black anodized aluminium
Weight		400 gram

Connection of antenna

There is HIGH VOLTAGE on the antenna terminals and it is therefore important that the

24 V DC is disconnected before the antenna is connected to the module.
