1756-L72EROMS 工业控制器 具有安全功能和标准控制器功能

Allen-Bradley 1756-L72EROMS是一款装甲GuardLogix控制器。它配有2个通道、4 MB标准内存、0.98 MB I/O内存和2 MB安全内存，允许以太网/IP网络上的标准和安全通信选项。该控制器的最大模拟I/O为4000，最大数字I/O和总I/O分别为128，000。1756-L72EROMS还附带一个额外的1 GB SD卡内存，已经安装到控制器上，但您可以将其升级到2 GB。

该控制器可支持每个网络模块多达256个以太网/IP和128个TCP网络连接。请注意，1756-L72EROMS控制器没有控制器冗余。可用的编程语言有结构化文本、顺序功能图(SFC)、继电器梯形逻辑(RLL)、仅支持RLL和附加安全应用说明的安全任务以及功能框图。该控制器有一个以太网RJ45 5类端口和一个全速USB端口。1756-L72EROMS尺寸为9.4 x 11.5 x 6.5英寸，重量为7.15千克或15.725磅，具有UL型4/4x外壳类型。

该控制器的标称输入电压为24V DC，输入电压范围为18-32V DC。连续隔离电压为30V，属于基本绝缘类型。这种隔离已经在707V DC下进行了60秒的类型测试，从电源到机柜，从非冗余以太网通道到非冗余以太网通道，从以太网通道到电源，但是冗余以太网通道之间没有隔离。该控制器有一个不可更换的保险丝，该保险丝已焊接到位，以防止因短路情况引起的火灾。

1756-L72EROMS的工作温度为0-60 ℃,储存温度为-40-85 ℃,最高环境温度为60 ℃,相对湿度为5-95%,无冷凝。该控制器在10-500 Hz下的工作振动为2 g，工作冲击为30 g，非工作冲击为30 g。

1756-L72EROMS

The Allen-Bradley 1756-L72EROMS is an Armor GuardLogix controller. It comes with 2 channels, a 4 MB standard memory, 0.98 MB I/O memory, and a 2 MB safety memory, allowing standard and safety communication options on EtherNet/IP networks. This controller has a maximum analog I/O of 4000 and maximum digital I/O and total I/O of 128,000 each. The 1756-L72EROMS also comes with an additional 1 GB SD card memory already installed to the controller, but you can upgrade it to 2 GB.

Up to 256 EtherNet/IP and 128 TCP network connections per network module can be supported by this controller. Note that the 1756-L72EROMS controller does not have controller redundancy. Programming languages available are structured text, sequential function chart (SFC), relay ladder logic (RLL), safety task that supports only RLL and the additional safety application instructions, and function block diagram. This controller has 1 Ethernet RJ45 Category 5 port and 1 full speed USB port. The 1756-L72EROMS measures 9.4 x 11.5 x 6.5 inches, weighs 7.15 kg or 15.725 lbs, and has a UL Type 4/4x enclosure type.

The nominal input voltage of this controller is 24V DC and its input voltage ranges from 18-32V DC. Continuous isolation voltage is 30V, which is of a basic insulation type. This isolation has been type-tested at 707V DC for 60 seconds and is from power to enclosure, non-redundant Ethernet channels to non-redundant Ethernet channels, and Ethernet channels to power, but there is no isolation between redundant Ethernet channels. This controller has a non-replaceable fuse that has been soldered into place to guard against fire hazards due to short circuit conditions.

The 1756-L72EROMS’s operating temperature is 0-60 ËšC and its storage temperature is -40-85 ËšC. It also has a maximum ambient temperature of 60 ËšC and a relative humidity of 5-95% non-condensing. This controller’s operating vibration is 2 g at 10-500 Hz, its operating shock is 30 g, and its non-operating shock is 30 g.
