The 193-EIMD module is an AC input interface module manufactured by Allen-Bradley/Rockwell Automation as an E3 Plus accessory in the E3 Plus overload relay series. The 193-EIMD module is specially designed and intended for use with the 193-EC and 592-EC devices. It comes with 4 inputs and it operates on a voltage rating of 110 to 120 Volts AC at a frequency of 50 to 60 Hertz. This module has a rated current range of 0.4 to 5000 Amps, and a nominal NEMA operating voltage of 600 Volts and it also comes with a nominal IEC operating voltage of 600/1000 Volts and it features a microprocessor-based overload type. This unit comes with both automatic and manual reset type options as well as a current adjustment ratio of 5:1. It also features an adjustable delay phase loss as well as a sensitive ground fault option.

Other features of Allen-Bradley 193-EIMD AC input interface module includes overcurrent jam detection, stall detection, under load detection, current imbalance, warning settings, and PTC thermistor monitoring. It also has 2 outputs and 4 inputs as well as a normally closed trip contact. While the 193-EIMD module comes without a normally open alarm contact, it is compatible with variable frequency drives and it conforms with the ODVA DeviceNet standards. The module is approved and certified for compliance with the CSA, UL, EN 60947-4-1, CE, cULus, CCC, and ABC standards. The E3 overload relays, including the 193-EIMD module, comes in 2 different configurations, including the E3 and E3 Plus configurations. The E3 overload relays provide configurable phase loss protection that allows the users to disable or enable the function as well as to set a time delay which can be adjusted from 0.1 to 25 seconds. It comes with a factory-set trip level at a current imbalance measurement of 100 percent.
