Compact Relay Switching for Industrial Control Systems
Interface relays provide electrical separation between low-power PLC or controller outputs and the circuits they need to switch. The BNMS R24V-1 combines a low-current DC coil with an SPDT changeover contact, allowing a 24 V DC control signal to operate compatible AC or DC loads while maintaining galvanic separation between the control and contact sides.
Its plug-in format makes the relay particularly practical in modular control-panel installations. If a relay requires replacement, the plug can be exchanged without replacing the complete compatible terminal assembly, helping simplify maintenance while its narrow construction supports space-efficient, high-density automation systems.
Typical Applications
- PLC input and output interfacing.
- Industrial control panels and electrical cabinets.
- Machine control and factory automation systems.
- Signal isolation and relay decoupling circuits.
- Process control and production equipment.
- Switching of compatible AC and DC control loads.
