Brand: @-LINK – Ai LinKe

Name: Cody leads to: LSPM2

Type: PROFIBUS agreement chip: LSPM2

About products:

The company prepares against the brand-new original packaging stock, the specialized PROFIBUS series products provider long.

The products are detailed:

Explain in detail

(1) ASICs chip SPM2 (Siemens PROFIBUS Multiplexer) With LSPM2 (Lean Siemens PROFIBUS Multiplexer) Used in simply from the chip of agreement of the station. Can be used in the sensor, executive body, switchgear, display device and electric thermocouple measurement. These two kinds of ASICs chips support PROFIBUS-DP agreement. LSPM2 adopts the small size to encapsulate, is suitable for the small application occasion. Transfer rate 12Mbit/s of the largest data.

(2) SPM2 has 64I/O location interface. Adopt 120 tubes of feet PQFP to encapsulate. Some I/O can set up as to input or export. There is I/O that diagnoses the location. SPM2 can totally deal with the data independently without needing extra microprocessor and other hardwares. So using SPM2 and some other peripheral devices can finish connecting PROFIBUS-DP function. LSPM2 has function as SPM2, but it has 32 I/Os only, PQFP which uses 80 tubes of feet encapsulates.

(3) SPM2 and LSPM2 can totally deal with the communication protocol independently. Only need to be in charge of it the foot is coupled to I/O signal line and on the bus cable. The operation of SPM2 and LSPM2 is from the station like one on PROFIBUS-DP. After it accepts from main website until one has not been misrepresented deliberately gently, can send out and reply the newspaper to the main website gently independently.

(4) Main technical parameter:

Support PROFIBUS-DP agreement.

The transfer rate 12Mbit/s of the largest data, can measure and adjust the transfer rate of the data automatically.

SPM2 adopts 120 tubes of feet PQFP to encapsulate, LSPM2 adopts 80 tubes of feet PQFP to encapsulate.

SPM2 has integrated 64I/O location(32 among them that can diagnose input) ,16 pieces of diagnosis location. LSPM2 has integrated 32I/O location(16 among them that can diagnose input) ,8 pieces of diagnosis location.

Some I/O can set up as to input or export.

Integrate guard the gate dog (WATCHDOG TIMER)

Interface 24MHZ or 48MHZ of the external clock.

5VDC supplies power.
