Allen-Bradley 193-EC2ZZ-W Analog Input Output Module

Allen-Bradley 193-EC2ZZ-W is a two-pole solid-state overload relay in the 193-EC family, designed for motor protection in industrial control circuits. It provides internal ground-fault protection (Series B & C variants) with a ground-fault sensing range of 1–5 A and supports motor continuous currents up to 90 A (≤ 90 A). The device is intended to work with the 193-EC E3/E3 Plus overload relay ecosystem and pairs with a 110/120 VAC input via the 193-EIMD input interface module. For mounting in control panels, it is used with the 193-ECPM2 Panel Mount Adaptor, fitting standard E3/E3 Plus assemblies. This catalog number is compatible with related 592-EC devices and is documented for internal ground-fault protection rather than external sensing methods, making it suitable for protecting small to mid-size motors in conveyors, pumps, fans, and other automation equipment. The 193-EC2ZZ-W variant follows the same grounding architecture as other EC2ZZ configurations and is described in Rockwell Automation literature as part of the motor-protection options available within the 193-E3/E3 Plus family.
