| Description | Current Monitor Relay; AC/DC Over/Undercurrent, Band; 24...240V AC/DC |
| Datasheet | Download Datasheet |
The Macromatic CMD10AD2U is a 22.5 mm current monitor relay with DPDT output and rated 5 A at 250 V AC, 5 A at 24 V DC, driven by a 24 to 240V AC/DC input.
It watches the monitored current for AC/DC Over/Undercurrent, band.
Its trip point adjusts anywhere across 5 to 100 mA, 0.05 to 1 A or 0.5 to 10 A.
The drop-out point is adjustable, 5 to 95% of the selected range.
It begins sensing 0 to 10 s after power is applied (adjustable).
It trips after 0.1 to 10 s (adjustable).
It has 35mm DIN Rail mounting and screw terminals.
