IO-Link actuator board delivers turnkey reference design for industrial monitoring and appliances

IO-Link執(zhí)行器評估板為工業(yè)監(jiān)測和電器提供交鑰匙參考設(shè)計

ST has introduced an IO-Link reference design for industrial beacons and home-appliance alarms, delivered ready-to-use as a fully built board complete with protocol stack and application software.

意法半導(dǎo)體為工業(yè)信號和電氣報警引入IO-Link參考設(shè)計，該參考設(shè)計作為一個完整的內(nèi)置板交付，配有協(xié)議棧和應(yīng)用軟件。

The EVLIOL4LSV1 board leverages ST’s L6364Q dual-channel IO-Link transceiver to handle communications and the IPS4260L intelligent low-side power switch for driving the indicator lights. The board can be directly connected to signaling systems such as smart tower lights used in factory automation, funnel material alarms for quantity-remaining or urgency-level awareness, and other system warnings. It also provides a fast way to test the IPS4260L and L6364Q ICs and has a 4-pin M12 connector for an IO-LINK master and a 5-pin SWD connector for programming.

EVLIOL4LSV1板利用意法半導(dǎo)體的L6364Q雙通道IO-Link收發(fā)器處理通信，并通過IPS4260L智能低邊功率開關(guān)驅(qū)動指示燈。該板可直接連接到信號系統(tǒng)，如工廠自動化中使用的智能燈塔、用于漏斗中物料剩余量警報或緊急液位/物位感知，以及其他系統(tǒng)警告。此外，它還提供了用于快速測試IPS4260L和L6364Q IC的方法，并配有用于與IO-LINK主設(shè)備連接的4針M12連接器和用于編程的5針SWD連接器各一個。

An STM32G071CB microcontroller, which hosts the ST proprietary IO-Link demo stack and the application software, handles system control and diagnostics, communicating with the transceiver and low-side switch.

STM32G071CB微控制器中運(yùn)行意法半導(dǎo)體專有的IO-Link演示協(xié)議棧和應(yīng)用軟件，可對系統(tǒng)控制和診斷進(jìn)行處理，同時與收發(fā)器和低邊開關(guān)進(jìn)行通信。

The L6364Q transceiver is fully protected and supports standardized IO-Link communication speeds including 38.4kbit/s COM2 and 230.4kbit/s COM3. The transceiver can operate in single or multibyte mode, as well as in transparent mode delegating control of IO-Link communications to the microcontroller by a simple URT interface. The in-built protection ensures EMC immunity up to 2.5kVpk surge pulse/500? coupling without additional protection elements.

L6364Q收發(fā)器受具有保護(hù)功能，支持標(biāo)準(zhǔn)化的IO-Link通信速度，包括38.4kbit/s COM2和230.4kbit/s COM 3。收發(fā)器既可在單字節(jié)或多字節(jié)模式下運(yùn)行，也可在透明模式下運(yùn)行——通過簡單的URT接口將IO-Link通信的控制委托給微控制器即可。內(nèi)置保護(hù)功能可確保EMC抗擾度高達(dá)2.5kVpk浪涌脈沖/500?，無需額外的保護(hù)元件。

The IPS4260L low-side driver has four outputs for driving loads with one side connected to supply voltage, each individually controlled by a signal such as a digital microcontroller output. It has a wide operating-voltage range, from 8V to 50V, and the current for each output can be independently programmed from 0.5A to 3.0A. The IC integrates overload and overtemperature protection for each channel and provides open-load, overload, and overtemperature diagnostic signals to aid system management and enhance reliability. The reference design also features ST’s SMBJ30CA TVS (transient-voltage suppression) diode to withstand surge pulses with 2? coupling on the supply rail.

IPS4260L低邊開關(guān)共有四個輸出用于驅(qū)動負(fù)載，負(fù)載的另外一側(cè)連接到電源電壓，每個輸出均由MCU的輸出信號進(jìn)行單獨(dú)控制。其擁有8V到50V的寬泛工作電壓范圍，各輸出的電流可在0.5A到3.0A之間可設(shè)置。該IC為各通道集成了過載和過熱保護(hù)，并提供負(fù)載開路、過載和過熱診斷信號，以幫助系統(tǒng)管理并提高可靠性。參考設(shè)計還具有意法半導(dǎo)體的SMBJ30CA TVS（瞬態(tài)電壓抑制）二極管，可承受電源軌上2?耦合的浪涌脈沖。

The EVLIOL4LSV1 is available now from the eSTore and ST distributors for $23.

EVLIOL4LSV1現(xiàn)可從電子商城和意法半導(dǎo)體分銷渠道購買。
