Allen-Bradley 1769-ECL

The Allen-Bradley 1769-ECL end cap terminates the end of a communication bus. The role of the right end cap in controller systems like the Allen-Bradley 1769-L32E system is to prevent the final I/O from being exposed when they are not connected by using expansion cables. Some important things to know about 1769-ECL end cap are that it has a relative humidity range for operation of 5 to 95%, noncondensing, and it also has an Electrostatic Discharge immunity rating of IEC 61000-4-2 and an 8 kilovolts air discharge rating from the International Electrotechnical Commission. The North American temperature code for the maximum temperature limitations of the 1769-ECL end cap is the T3C code, and this product’s radiated radio frequency immunity rating is the IEC 61000-4-3 rating for an environment rated at 10V/m with 1 kHz sine-wave, 80% AM from 80 to 2700 MHz, 10V/m with 200 Hertz, 50% Pulse, 100% AM at 900 MHz, and 10V/m with 200 Hertz, 50% Pulse, 100% AM at 1890 MHz.The Allen-Bradley 1769-ECL end cap vibrates 5 g, at 10 to 500 Hertz frequency while operating. It is rated for 20 g of operating shock when mounted on a DIN rail and 30 g when mounted on a panel. The 1769-ECL end cap is rated for 30 g of nonoperating shock on a DIN rail and 40 g on a panel. The 1769-ECL end cap can sometimes become susceptible to electrostatic discharge, and if this happens, the routine operations of this part might be hindered, and internal damage may occur. To avoid this situation and the safety risks that could occur if this happens, always make sure to follow the proper safety protocols when handling this equipment. This end cap adheres to all industrial health and safety obligations.

The 1769-ECL is a left-end cap that is made by Allen-Bradley. This terminator or end cap component is included in the 1769 controller series. This part terminates the end of a 1769 series controller’s communication bus. This component is compatible with CompactLogix or MicroLogix 1500 devices. The bus current draw limit for this unit is rated at 5 milliamperes at 5 Volts DC. The rated operating altitude is 6562 feet (2000 meters). The 1769-ECL has not been issued an IEC temperature code, however, it has a North American temperature code of T3C. The approximate shipping weight of this unit is 0.286 pounds. It is housed in an open-type enclosure. The operating temperature range is specified between 32 degrees and 140 degrees Fahrenheit and the module is tested to withstand dry heat and cold as well as thermal shock. The unit is certified for operation in environments that have a relative humidity of 5 percent to 95 percent noncondensing. It can withstand operational vibrations reaching 5 G between 10 Hertz and 500 Hertz. The rated operational shock limit is 20 G when mounted using a DIN rail. The rated operational shock limit is 30 G when mounted using a panel mount. The rated non-operational shock limit is 30 G when mounted using a DIN rail. The rated non-operational shock limit is 40 G when mounted using a panel mount. This unit is rated for electrostatic discharge ESD immunity of 8 Kilovolt air discharges and is classified in the emissions rating of CISPR 11 Group 1, Class A.
