Dynalco SST-7200 Digital Speed Switch數(shù)字速度開關(guān)
Description產(chǎn)品簡介
Dynalco SST-7200是一個(gè)PC可編程、安裝在DIN軌道上的速度開關(guān)，配有2個(gè)標(biāo)準(zhǔn)繼電器，通過提供可靠的欠速/超速保護(hù)，保護(hù)旋轉(zhuǎn)設(shè)備免受故障的影響。SST-7200 is a PC-programmable, DIN rail mounted speed switch with 2 standard relays to protect your rotating equipment from failure by providing reliable under/over speed protection
SST-7200, SST-7400 SST-7200D & SST-7400D Product Data Sheet
Instrumentation & Controls Speed Switch / Transmitter
- Accepts 2 or 3-wire speed sensors
- 0 - 50 KHz input frequency range
- 4 – 20 mA output (isolated)
- 0 – 5 / 0 – 10 VDC linear output
- 50 msec relay response time
- 2 or 4 SPDT relays
- Failed (open) pickup sensing
- Square wave repeater output
- 10 – 36 VDC input supply power
- Available input isolation transformer
- PC programmable over USB port
- Front Keypad programmable (for models with LCD Display)
- –I suffix:
Isolated RPM input from the power supply
ground by more than 300V peak
- –AC suffix (for models with LCD Display):
AC supply voltage to use for the VAC L / VAC N terminals (see Electrical specifications)
SST-7200D和SST-7400D接受脈沖輸入，并提供4-20mA輸出，該輸出非常精確和穩(wěn)定，溫度變化代表本地面板儀表或PLC模擬輸入卡的旋轉(zhuǎn)機(jī)械速度。它們還提供2個(gè)“SST-7200（D）”和4個(gè)“SST-7400（D）”快速繼電器對超速/低速條件的響應(yīng)。應(yīng)用范圍包括工業(yè)發(fā)動機(jī)、渦輪機(jī)械和泵的速度測量和超速保護(hù)。SST-7200(D) & SST-7400(D) accept a pulsed input and provide a 4-20 mA output that is very accurate and stable with temperature changes representing speed of rotating machinery for a local panel meter or PLC analog input card. They also provide 2 “SST-7200(D)” and 4 “SST-7400(D)” quick relay responses to over/under speed conditions. Applications include speed measurement & overspeed protection of industrial engines, turbomachinery and pumps.
