EI SERIES

CURRENT CONTROL RELAY

UL cUL listed

• 3 Product Types for Measurement Accuracy

• Under or Over Current - Selectable

• Space Saving 22.5mm Wide

• DIN-Rail / Surface Mount

Three product types; EIL (2 to 500 mA), EIH (.1 to 10A) and EIT (10 to 100A with

current transformers) provide selectable over or under current control.

AC/DC control without memory.

When the value of the controlled current, either AC or DC, reaches the threshold

displayed on the front face, the output relay change state at the end of time delay T1.

It returns to the initial state instantly when the current drops below the hysteresis

threshold, or when the power supply is disconnected.

AC/DC control with memory.

When the value of the controlled current reaches the displayed threshold, the output relay

changes status at the end of time period T1 and remains locked in this position. To reset

the memory function the auxiliary supply must be disconnected.

Over-current function (UPPER).

The power-on time delay T2 prevents current peaks due to motor starting.

The delay on upward crossing of threshold T1 provides immunity to transients and other

interference, thereby preventing spurious triggering of the output relay.

Under-current function (UNDER).

The power-on delay T2 prevents the occurrence of current troughs. The delay on

downward crossing of threshold T1 provides immunity to random dips, thereby preventing

spurious triggering of the output relay.

Note: In underload function, the absolute value of the hysteresis

cannot be greater than the measurement range maximum.
