The 193-EC2AB relay is an output relay from Allen-Bradley's Bulletin 193-EC series, specifically designed for industrial applications. These relays are available in two configurations and offer options for either internal or external ground fault sensors. Additionally, they come with current monitor relays that have external ground fault sensors or voltage monitoring capabilities. The 193-EC series includes protective relays with an adjustable current range from 0.4 to 5000 Amps and is compatible with various contactor sizes. The devices in this series facilitate communication via DeviceNet or EtherNet/IP networks and support a range of optional functions.
The 193-EC2AB relay adheres to multiple standards, including CSA C22.2 (No. 14), EN 60947, UL 1053, and UL 508, and it is CE, cUL, and CE certified. It is built to withstand harsh industrial environments, with an operational temperature range from -20 to 55 degrees Celsius (-4 to 131 degrees Fahrenheit) and storage temperatures ranging from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). This relay is configured as an E3 Plus unit with an internal ground fault sensor, offering extra functionality. It features an adjustable current rating between 1 and 5 Amps, has 4 inputs and 2 outputs, and supports contactor sizes from C09 to C23. The relay has a rated insulation voltage of 690 Volts AC and operates within a frequency range of 20 to 250 Hertz. It weighs approximately 0.8 kilograms (1.7 pounds).
