BECKHOFF倍福el3008模擬量端子模塊el3008原裝現貨德國PLC模塊現場總線EL3008 | 8-channel analog input terminal -10…+10 V, single-ended, 12 bit
The EL3008 analog input terminal processes **s in the range between -10 and +10 V. The voltage is digitised to a resolution of 12 bits, and is transmitted, electrically isolated, to the higher-level automation device. The power contacts are connected through. The reference ground for all inputs is the 0 V power contact. The ** state of the EtherCAT Terminal is indicated by light emitting diodes.

現場總線
Beckhoff 公司為所有常用的 I/O 信號和現場總線系統提供全系列的總線組件。我們提供類型豐富的 I/O 組件,供您選擇較適合的總線系統:
EtherCAT
EtherCAT(Ethernet for Control Automation Technology,用于控制和自動化技術的以太網)是一種用于工業自動化的實時以太網解決方案,性能優越,使用簡便。
Lightbus
這種經過驗證的 Beckhoff 光纖總線系統具有較為優秀的抗 EMI 性能,易于安裝,數據流快速、循環且具有確定性。
PROFIBUS
PROFIBUS 作為一種快速總線,被廣泛應用于分布式外圍組件(PROFIBUS-DP)。除了 PROFIBUS-DP 和 FMS 以外,Beckhoff 還支持驅動器通訊標準 PROFIBUS MC。
Interbus
Interbus 易于配置,通訊快速而可靠。主/從系統的移位寄存器協議可提供高效循環通訊。
CANopen
通過有效利用總線帶寬,CANopen 可在即使相對較低的數據傳輸速率時也能實現較短的系統響應時間。秉承了 CAN 的傳統優點,例如數據安全性高且具備多主站能力。
DeviceNet
DeviceNet 是一種傳感器/執行器總線系統,起源于美國,但現在在亞洲和歐洲也被越
