【英文介绍】

The Allen-Bradley 1756-L1M2 is a ControlLogix 5550 controller. It has 1 MB of user-available memory, but no non-volatile memory. It is capable of controlling local and remote I/O across DeviceNet, ControlNet, and universal remote I/O networks. It has an open housing type rating and weighs 0.35 grams or 12.5 ounces. The controller has Group 1 Class A radiation.

The 1756-L1M2 has an average power consumption of 4.8W and an average heat dissipation of 16.4 BTU/ hour. Its average backplane current is 1.05 A at 5V DC and 0.02 A at 24V DC.

The controller operates in a temperature range of 0 to 60 degrees Celsius, while its storage temperature ranges from -40 to 85 degrees Celsius. It also has a non-condensing relative humidity between 5% and 95%.

It has a maximum peak acceleration of 2 G of vibration at 10 to 500 Hz, a 30 G peak operating shock at 11 ms, and a 50 G peak storage shock at 11 ms. It also has an isolation voltage of 30V, and the controller has been tested to withstand 500 volts for 60 seconds.

The programming cables compatible with the 1756-L1M2 controller are the 1756-CP3 and 1747-CP3. When it needs to be replaced, the battery should only be 0.59g lithium battery 1756-BA1.

The 1756-L1M2 has conducted RF immunity of 10 VRMS and 1 kHz sine wave 80%AM in the range of 150 kHz to 80 MHz. The ESD immunity of contact discharge is 6 kV, and the ESD immunity of air discharge is 8 kV. It also has EFT/B immunity: +/-2 kV at 5kHz on the communication port and +/-4 kV at 2.5 kHz on the power port. Radiated RF immunity is 10V/m (200 Hz), 50% pulse, 100%AM (900 MHz) and 10V/m (1 kHz sine wave, 80%AM (30 MHz to 1000 MHz).
