YZ-K star delta timing module: delayed connection, time range 1.5-30 seconds, suitable for star delta starters below 30kW/400V.
ZM-K timing module: delayed connection, providing three time ranges of 0.2-4 seconds, 1.5-30 seconds, and 12.5-250 seconds, suitable for controlling timing.
RM-K Relay Interface Module: Used as an interface between PLC and AC operated K-series contactors (up to 18.5kW), with an input of 24V DC and an output of 380-415V AC or 215-250V AC.
All modules come standard with LED status indicators, with NP-K and RM-K having built-in RC suppressors.
5.4 Other Components
Mechanical Interlock MV-e: Used to achieve mechanical interlocking between two contactors to prevent simultaneous closure.
Electromagnetic retaining lock head MV-BN: maintains contact state when the coil is powered off, suitable for occasions requiring memory function, voltage range 12-240V AC/DC.
Pneumatic Timer PZ: Provides delayed connection or delayed disconnection, with a time range of 0.1~3 seconds, 0.1~30 seconds, and 10~180 seconds.
Single pole connector: used to connect 3-pole contactors in parallel to form a 1-pole high current contactor, which approximately doubles the rated thermal current. Suitable for DL 4 K~11 K and DL 15 K~18 K.
Three pole connector: used for connecting contactors and manual motor starters, model MSU-K.
Motor protection relay M 06
M 06 is a phase sequence fault sensitive motor protection relay with a current setting range of 0.1~11.5 A, equipped with:
1 normally open+1 normally closed auxiliary contact for electrical isolation
Manual/automatic reset optional
The setting parameters can be protected by a sealing cover
Pre wired control terminal, can be directly installed under the contactor (compatible with DL/KL series)
Phase loss protection function
Coil voltage code and selection guidance
All contactor and relay order numbers must be accompanied by a voltage code (two digits) and a coil type suffix. For example, when ordering DL 4 K-101, voltage codes such as "06" (24V AC) or "40" (220V DC) need to be added. Color identification is only applicable to compact contactors (HL 4 K/HL 8 K and DL 4 K~DL 18 K).
Standard voltage (stock available):
AC:24V、42V、110V、230V、400V
DC:24V、110V、220V
Other voltages can be customized.
Application scenarios and selection suggestions
PLC output isolation and signal amplification: Choose KHi interface relay (1.8W, with LED) or standard KHDC relay (3W).
Motor direct start (≤ 18.5kW): Select DL series contactor according to power, and cooperate with M 23 K or M 40 K thermal overload relay.
Motor forward and reverse control: Choose KLW series reverse contactor (≤ 4kW) or use two DL contactors with MV-e mechanical interlock.
Star Triangle Start: Choose two DL contactors and one YZ-K timing module, or use a dedicated Star Triangle kit.
Low noise occasions (hospitals, office buildings): Choose KLb or DL series silent (with rectifier) contactors.
DC load switching: choose DLg series DC switching contactor (six fold disconnect) or KLDC series.
Compact control system: Top mounted NP-K, ZM-K, RM-K modules are selected, eliminating the need for external relays or timers.
