Description

The 1769-ECL is a terminator or left-end cap component made by Allen-Bradley and is part of the 1769 product family. This component is compatible with CompactLogix or MicroLogix 1500 devices and terminates the end of a controller’s communication bus. The bus current draw limit for this unit is rated at 5 milliamperes at 5 Volts DC. It is housed in an open-type enclosure and has been tested to withstand dry heat and cold as well as thermal shock.

The Allen-Bradley 1769-ECL is a left-end cap or terminator that is a part of a 1769 controller. The 1769-ECL terminates the end of the controller’s communication bus. It is for Micrologix 1500 or Compactlogix devices. Its greatest bus current draw is 5 mA at 5V DC. It comes with a 6562 feet operating altitude and has a North American temperature code of T3C but no IEC temperature code. It has an approximate shipping weight of 0.286 lbs and an open-type enclosure rating to ensure safety which can adapt it to certain conditions such as reducing the risk of fire.

The 1769-ECL has an operating temperature of 32 – 140 °F tested at cold, dry heat, and thermal shock. It has a non-operating temperature of -40 – 185 °F tested unpackaged during cold, dry heat and thermal shock. The Allen-Bradley 1769-ECL has a 5 – 95% noncondensing relative humidity. Its vibration reaches 5 g at 10 – 500 Hz when operating. It has an operating shock of 20 g when DIN rail mounted and one of 20 g when panel-mounted. The 1769-ECL’s non-operating shock is 30 g on a DIN rail mount and 40 g on a panel mount. It has Group 1, Class A emissions and ESD immunity 8 kV air discharges.
