The 193-EC2AB relay is an Allen-Bradley/Rockwell Automation output relay component from the Bulletin 193-EC product line. These output relays are available in 2 configurations and they are also available in variants with internal or external ground fault sensors and with current monitor relays with external ground fault sensors or voltage monitoring. The 193-EC series protective relays are available with an adjustable current range from 0.4 to 5000 Amps and various contactor sizes. The series supports communication through either the DeviceNet or EtherNet/IP networks and it provides a choice of optional functions. The 193-EC2AB output relay is made in accordance with standards such as the CSA C22.2 (No. 14), EN 60 947, UL 1053, and the UL 508 standards. The unit is also certified according to the CE, cUL, and CE standards.

The 193-EC2AB output relay operates in demanding industrial environments and it allows for an operating temperature range of -20 to 55 degrees Celsius or -4 to 131 degrees Fahrenheit. The unit can be stored at temperatures not lower than -40 degrees Celsius or -40 degrees Fahrenheit and not higher than 85 degrees Celsius or 185 degrees Fahrenheit. The 193-EC2AB output relay is configured as an E3 Plus unit with an internal ground fault sensor that provides additional functionalities. The adjustable current rating of the unit is 1 to 5 Amps. As far as the integrated I/O, the 193-EC2AB relay has 4 inputs and 2 outputs. The supported contactor size is C09 to C23. The unit has a rated insulation voltage of 690 Volts AC and rated frequency of 20 to 250 Hertz. This reliable system component has an approximate weight of 0.8 kilograms or 1.7 pounds.
