KM2604 | 4-channel relay module 230 V AC, 16 A

The KM2604 terminal module combines four pluggable power relays in one fieldbus module. The high switching capacity of 16 A at 230 V AC enables direct mains connection of consumers with high current consumption. The relays are positioned at the top and can therefore be exchanged easily.
