⚡ At a Glance
- • Switching Performance: Power contact with 1CO configuration for single-pole changeover switching
- • Best for: Control circuits and maintenance tasks requiring compact 24 V DC switching
- • Not ideal for: Applications that need multi-pole switching or integrated communication functions
Plug-in miniature power relay with a power contact and 1CO contact configuration. Supplied new and specified with a listed weight and external dimensions.
Reliable single-pole switching – with 1CO power contact
The 1CO designation indicates a single changeover contact, combining common, normally open and normally closed connections in one pole. That arrangement allows switching between two circuits using a single contact set.
Straightforward changeover wiring suits many control schemes and simplifies panel logic for single-circuit switching applications.
Simple installation and service – with plug-in format
Plug-in construction matches a compatible socket or base for insertion and removal during installation. Connections are arranged for a replaceable module rather than permanent mounting.
Quick swapout during maintenance reduces downtime and speeds replacement without complex rework.
Designed for common DC control supplies – with 24 V DC input
An input voltage rating of 24 V DC establishes the activation level for the relay's coil circuit. That voltage is a standard control level in many industrial and automation systems.
Compatibility with 24 V DC control supplies makes the unit suitable for typical industrial control panels and automation equipment.
