LC1D18BD
Schneider Electric
The LC1D18BD is an 18A 3-pole contactor with 24V DC coil from the TeSys D series. Rated 7.5kW at 400V AC-3, it is ideal for PLC-controlled motor starting applications where direct DC coil drive is preferred. With built-in auxiliary contacts and 45mm DIN rail mounting, it suits compact control panel designs for conveyors, pumps, fans, and general automation.
**Q: Can the LC1D18BD directly interface with a PLC output?**
A: Yes, the 24V DC coil can be driven directly by PLC transistor outputs (within the coil power rating), eliminating the need for interposing relays.
