描述

The 84871004 is a current control relay from the EI Series designed to monitor and control AC or DC currents with high measurement accuracy. It features three product types (EIL, EIH, and EIT) covering measurement ranges from 2 mA to 100 A, with selectable over-current or under-current control modes and adjustable hysteresis from 5 to 50% of the displayed threshold. The unit operates on 24 VDC or 24/48/110/120/230 VAC ±15% at 50/60 Hz, consuming only 3 VA, and includes a SPDT relay output with AgCdO contacts rated for 8 A AC resistive loading. With setting accuracy of ±10%, repeat accuracy of ±0.1%, and configurable time delays (power-up delay T2 from 1 to 20 seconds and threshold overrun delay T1 from 0.1 to 3 seconds), this relay provides reliable current monitoring for motor protection, load control, and industrial automation applications where precise current thresholds and immunity to transients are essential.
