PRODUCT DATA

4/6-ch. Input Module LAN-XI 51.2 kHz Type 3050 The core of the LAN-XI range of input modules, these modules are designed to cover as many sound and vibration measurement applications as possible.

Type 3050 comes in two basic variants, offering the choice between four and six high-precision input channels with an input range from DC to 51.2 kHz Type 3050 works equally well as a single-module system, or as part of a large LAN-XI measurement system – making it one of the most flexible data acquisitions modules on the market. In addition, interchangeable front panels give you the flexibility to use a wide range of transducers.

One Cable Operation You can use standard LAN cables for synchronous sampling between modules and system power, thanks to Power over Ethernet (PoE). This minimises the number of cables required and results in lower cost, less downtime, easier maintenance, and greater flexibility of installation.

Power over Ethernet PoE is implemented according to IEEE 802.3af. PoE is wired Ethernet LAN technology that, with a suitable PoE LAN switch, allows the power needed for each module to be carried by screened shielded twisted pair (S/STP or S/FTP) CAT6 LAN cables rather than by separate power cables. This minimises the number of cables required and results in lower cost, less downtime, easier maintenance and greater installation flexibility. PoE switches, such as 10-port Gigabit Managed Switch with PTP and PoE (8 ports) UL-0265, and PoE Injectors, such as ZyXEL® PoE-12 Power over Ethernet (a single-port PoE injector), can be used.

Built for Field and Lab Use The modules and the detachable front plates are cast in magnesium for maximum stability, light weight, and tough field use.

Interchangeable Front Panels The modules allow front panels to be interchanged freely, with a variety of connectors for different transducers and applications. This results in fewer patch panels, less cable “spaghetti”, fewer cable adaptors and faster system setup.

Independent Channels The input channels on a module can be set up independently. You can set up the high-pass filters and input gain separately and attach different types of transducer to different channels.

IEEE 1451.4 Transducers All input modules support TEDS transducers. This allows automatic front-end and analyzer setup based on TEDS information stored in the transducer, for example, sensitivity, serial number, manufacturer and calibration date. The individual frequency response of a transducer can be corrected for using PULSE’s Transducer Response Equalisation, REq-X, to achieve higher accuracy over extended frequency ranges.

Overload Constant Current Line Drive (CCLD) conditioning monitors the supply voltage used by CCLD-compatible transducers. Available CCLD transducers include:

• Accelerometers

• Charge amplifiers

• Microphone preamplifiers

• Tacho probes

If conditioning errors, such as a broken cable, are detected, an error is indicated as an overload on the specific channel connector (using a ring-LED around the connector) and in the PC software.

Overload indications for input channels include (see Specifications for details):

• Signal overload with adjustable detection level

• CCLD overload: detection of cable break, short-circuit or CCLD transducer working point fault

• Microphone preamplifier overload: detection of microphone preamplifier current consumption too high or too low

• Common mode voltage overload – relevant when input coupling is floating

Ground-loop Noise Suppression The module’s floating/grounded, differential input design and the fact that all external connections (LAN, power supply) are galvanically isolated in the module provide optimal ground-loop noise suppression.

ACQUISITION PERFORMANCE

Each LAN-XI module generates data at almost 20 Mbit/s when measuring six channels at 51.2 kHz bandwidth. The modules are capable of handling their own maximum traffic while the built-in switch in the frame’s backplane has more than sufficient capacity. This means that bottlenecks can only occur outside these, for example in:

• External switches

• PC

For convenience, it is possible to daisy-chain LAN-XI frames. However, it is not recommended to daisy-chain more than two frames. For larger configurations, a star configuration with a central switch is recommended.

This must have a switch capacity well beyond N × 20 Mbit/s, where N is the total number of modules

PTP PERFORMANCE

PTP Synchronisation (with 1 Gigabit LAN Switch):

Typical sample synchronisation better that 200 ns (approx. ±0.07° @ 1 kHz, ±2° @ 25.6 kHz) Tested with:

• Cisco® SG300-10MP, 10-port 10/100/1000 Managed Gigabit Switch with Maximum PoE (8 ports)

• Netgear® 5-port Gigabit Switch GS105 Better performance can be expected with a dedicated PTP switch:

• UL-0265: 10-port Gigabit Managed Switch with PTPv2 and PoE (8 ports).

This is a dedicated PTP switch, preconfigured for optimal use with

While in protection mode, the input is partly switched off and the input impedance is greatly increased. (The measured value will be strongly attenuated but still detectable) In DC mode –10 Vpeak range, the detection limit is ±12 V. In all other measuring modes (except CCLD) the limit is ±50 Vpeak including DC component or ±12 Vpeak AC (In CCLD mode the limit is +50/–2 Vpeak including DC component or ±12 Vpeak AC) In the 31.6 V range, the limit is ±50 Vpeak
