Allen-Bradley  1756-L63XT  控制器  可承受极端温度

【产品详情】

Allen-Bradley 1756-L63XT 是一款 ControlLogix 控制器，可承受极端温度。该控制器也称为极端环境 ControlLogix 控制器，因为它的工作温度高于大多数控制器。1756-L63XT 的工作温度范围为 -25 至 70 摄氏度，而其存储温度为 -40 至 85 摄氏度。它的最高周围空气温度为 70 摄氏度。但是，即使使用 1756-L63XT 控制器，使用 1756-A7LXT 机箱时，周围的空气温度范围也会略有降低;范围变为 -25 至 60 摄氏度，低 10 摄氏度。但是当控制器与 FLEX I/O-XT 产品一起使用时，它可以承受 -20 至 70 摄氏度，比单独使用时低 5 摄氏度。

该控制器具有 8 MB 的用户内存和 478 kb 的 I/O 内存供您使用。您也可以为其使用可选的非易失性存储器，但只能使用 64 MB （1784-CF64） 或 128 MB CompactFlash 存储卡 （1784-CF128）。它还具有 1 端口 RS-132 串行内置通信端口。与此控制器兼容的 ControlLogix 机箱包括 1756-A4LXT、1756-A5XT、1756-A7LXT 和 1756-A7XT。

1756-L63XT 的最大数字 I/O 和总 I/O 分别为 128,000 个，最大模拟 I/O 为 4000。它有三个控制器任务，即事件任务：所有事件触发器，32 个任务，每个任务 100 个程序。它最多可以支持 250 个控制器连接，以及属于同一 ControlNet 网络的相同控制器的控制器冗余。1756-L63XT 控制器可用的通信选项包括 ControlNet、DeviceNet、远程 I/O、SynchLink、EtherNet/IP、Data Highway Plus 以及第三方过程和设备网络。该控制器还提供串行端口通信，即 DF1 无线电调制解调器、DF1 全/半双工、ASCII、通过逻辑的 Modbus 和 ASCII。

该控制器的电流消耗在 5.1V DC 时为 1200 mA，在 24V DC 时为 14 mA。它还具有 3.5 W 的功耗和 11.9 BTU/hr 的散热。其连续隔离电压为30V，并在720V DC下进行了60秒的型式试验。它的相对湿度为 5% 至 95%（非冷凝）。1756-L63XT 在 10 至 500 Hz 时的振动为 2 g，工作冲击为 30 g，非工作冲击为 50 g。

【英文介绍】

The Allen-Bradley 1756-L63XT is a ControlLogix controller that can withstand extreme temperatures. This controller is also known as the Extreme Environment ControlLogix controller because it operates at a higher temperature than most controllers. The 1756-L63XT has an operating temperature range of -25 to 70 degrees Celsius, while its storage temperature is -40 to 85 degrees Celsius. Its maximum ambient air temperature is 70 degrees Celsius. However, even with the 1756-L63XT controller, the ambient air temperature range is slightly reduced when the 1756-A7LXT chassis is used; The range changes to -25 to 60 degrees Celsius, 10 degrees lower. But when the controller is used with the FLEX I/O-XT product, it can withstand -20 to 70 degrees Celsius, which is 5 degrees lower than when used alone.

The controller has 8 MB of user memory and 478 kb of I/O memory for you to use. You can also use optional non-volatile memory for it, but only 64 MB (1784-CF64) or 128 MB CompactFlash memory card (1784-CF128). It also has a 1-port RS-132 serial built-in communication port. The ControlLogix chassis compatible with this controller include the 1756-A4LXT, 1756-A5XT, 1756-A7LXT, and 1756-A7XT.

The 1756-L63XT has a maximum digital and total I/O of 128,000, respectively, and a maximum analog I/O of 4000. It has three controller tasks, namely event tasks: all event triggers, 32 tasks, 100 programs per task. It can support up to 250 controller connections, as well as controller redundancy for the same controllers belonging to the same ControlNet network. Communication options available for the 1756-L63XT controller include ControlNet, DeviceNet, Remote I/O, SynchLink, EtherNet/IP, Data Highway Plus, and third-party process and device networks. The controller also provides serial port communication, namely DF1 radio modem, DF1 full/half duplex, ASCII, Modbus via logic, and ASCII.

The current consumption of this controller is 1200 mA at 5.1V DC and 14 mA at 24V DC. It also has 3.5W power consumption and 11.9 BTU/hr heat dissipation. It has a continuous isolation voltage of 30V and was type-tested for 60 seconds at 720V DC. Its relative humidity is 5% to 95% (non-condensing). The 1756-L63XT has a vibration of 2 g at 10 to 500 Hz, a working shock of 30 g, and a non-working shock of 50 g.
