Brand New Allen Bradley 1756-CNBR Module

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

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

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