The relay module provides 4, 8, 16, 20, or 32 relays, either mechanical Finder 46.61-024-DC relays or Autonics SRS1 solid state relays. These relay modules can be populated with a mixture of mechanical relays or solid state relays to suit the loads being switched.
Relay control can be made via terminals or through a ribbon cable connected to a PLC.
There are terminals for an external 24V DC supply which powers the PLC interface when driving the relays from a PLC via the ribbon cable.
RM-8WAY-24VAC: Relay control is via terminals using an external 24V AC or DC supply.
