AI模块BECKHOFF全新KL3122
KL3122 | 2 通道模拟量输入端子模块， 0/4…20 mA
KL3112 和 KL3122 模拟量输入端子可处理 0 - 20 mA 和 4 - 20 mA 范围内的信号。电流被数字化后的分辨率为 16 位（默认为 15 位），并在电隔离的状态下被传送到上一级自动化设备。总线端子模块的输入通道有差分输入，并具有一个公共的内部接地电位端。KL3112 / KL3122 型端子模块有 2 个通道。该端子模块可监测开路或过载状态，其状态通过 K-bus 传到控制器。运行 LED 指示与总线耦合器的数据交换状态。故障 LED 指示过载状态。

Top view Contact assembly EL2901 | Potential supply terminal, TwinSAFE, 24 V DC, 10 A
The EL2901 Safety EtherCAT Terminal is a potential power supply terminal and enables the setting up of TwinSAFE groups with safe power supply (24 V DC, up to 10 A). If the TwinSAFE Terminal detects a fault, it switches to safe state (fail safe). Safe potential groups can be created within a terminal strand using the EL2901. The EL2901 meets the requirements of IEC 61508 SIL 3 and DIN EN ISO 13849 PL e.
