1756-L72EROM 控制器 可用于数据和逻辑

【产品详情】

Allen-Bradley 1756-L72EROM是一款装甲ControlLogix控制器。它最多可以处理 32 个任务，每个任务有 1000 个程序。它有一个 4 MB 内存可用于数据和逻辑，一个 0.98 MB 的 I/O 内存，以及一个用于备份内存的 1 GB SD 卡。该控制器的最大数字 I/O 和总 I/O 均为 128,000，最大模拟 I/O 为 4000。

该控制器配有 1 个 B 型 2.0 全速 USB 端口和 4 个以太网 M12 5E 类端口。此控制器可支持每个网络模块多达 256 个 EtherNet/IP 连接和 128 个 TCP 网络连接。请注意，此控制器没有可用的串行端口通信。1756-L72EROM控制器还支持最多 500 个控制器连接，但不支持控制器冗余。该控制器提供的编程语言包括结构化文本、继电器梯形图、顺序功能图 （SFC） 和功能块。1756-L72EROM 配备 UL Type 4/4x 外壳，尺寸为 9.4 x 11.5 x 6.5 英寸，重量为 15.50 磅或 7.04 千克。

输入电压范围为18-32V DC，标称输入电压为24V DC。不可更换的保险丝焊接到位，可防止因短路条件而发生火灾。1756-L72EROM 的连续隔离电压为 30 V，属于从非冗余以太网通道到非冗余以太网通道、以太网通道到电源以及电源到外壳的基本绝缘类型。冗余以太网通道之间不存在隔离。该控制器的隔离已在 707V DC 下进行了 60 秒的型式测试。1756-L72EROM 的非冷凝相对湿度为 5-95%。工作温度范围为0-60°C，非工作温度范围为-40-85°C。该控制器在 10-500 Hz 时还具有 2 g 的工作振动、30 g 的工作冲击和 50 g 的非工作冲击。

【英文介绍】

The Allen-Bradley 1756-L72EROM is an armored ControlLogix controller. It can handle up to 32 tasks, each with 1,000 programs. It has a 4 MB memory for data and logic, a 0.98 MB I/O memory, and a 1 GB SD card for backup memory. The controller has a maximum digital and total I/O of 128,000 and a maximum analog I/O of 4000.

The controller is equipped with one Type B 2.0 full speed USB port and four Ethernet M12 Class 5E ports. This controller can support up to 256 EtherNet/IP connections and 128 TCP network connections per network module. Note that there is no serial port communication available for this controller. The 1756-L72EROM controller also supports up to 500 controller connections, but does not support controller redundancy. The programming languages provided by the controller include structured text, relay ladder diagram, sequential function diagram (SFC), and function blocks. The 1756-L72EROM comes with a UL Type 4/4x housing that measures 9.4 x 11.5 x 6.5 inches and weighs 15.50 pounds or 7.04 kg.

The input voltage range is 18-32V DC and the nominal input voltage is 24V DC. Non-replaceable fuses are welded in place to prevent fires due to short circuit conditions. The 1756-L72EROM has a continuous isolation voltage of 30 V and is the basic insulation type from non-redundant Ethernet channel to non-redundant Ethernet channel, Ethernet channel to power supply, and power supply to housing. There is no isolation between redundant Ethernet channels. The isolation of the controller has been type-tested for 60 seconds at 707V DC. The 1756-L72EROM has a non-condensing relative humidity of 5-95%. The operating temperature range is 0-60°C and the non-operating temperature range is -40-85°C. The controller also has 2 g operating vibration, 30 g operating shock and 50 g non-operating shock at 10-500 Hz.
