The CARLO GAVAZZI DIB71CB485A is a high-precision monitoring relay designed for 1-phase true RMS AC/DC over or under current detection. Manufactured in China, this relay provides reliable current monitoring through an internal shunt, suitable for various industrial applications requiring accurate current measurement and control.
Key Features
TRMS AC/DC over or under current monitoring relay
Current measurement via internal shunt with selectable ranges from 0.1 mA to 5 A AC/DC
Adjustable measuring range, hysteresis, and delay (0.1 to 30 seconds)
Programmable latching or inhibit functions at set levels
Output: 5 A SPDT relay with Normally Open or Normally Closed contact configuration
Mountable on DIN-rail (DIN/EN 50 022 standard) in a 35.5 mm housing
LED indicators for relay status, alarm, and power supply
Galvanically separated power supply for enhanced safety and noise immunity

Input and Output Details
Output: 5 A SPDT relay, selectable N.D. or N.E.
Input terminals: Z1, Y1 with disabled or enabled options (< 500 Ω)
Inhibit contact: disables relay operation during maintenance or transitions
Functionality and Operation
The relay operates based on the measured current exceeding or dropping below the set threshold, with adjustable hysteresis and delay settings. It features a latching function for maintained relay operation and an inhibit function to prevent false alarms during system transitions. The relay provides visual indication via LEDs for power, alarm, and relay status.
Physical and Mounting Details
Housing: 35.5 mm DIN-rail compatible
Mounting: Back or front panel mounting
Additional Information

Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
