Siemens LOGO! 9 Series Logic Module 12/24RCEO, 8-Input, Digital Input, 4 Outputs, Relay Output

This logic module provides programmable control for small automation tasks, accepting digital signals and switching loads via relay outputs. It operates from a 24Vdc supply, includes a user display and an Ethernet communications port, and offers battery-backed operation to retain configuration and runtime data. Designed for DIN mounting, it integrates into control panels to manage discrete inputs and relay-driven outputs within industrial environments.

• Eight digital inputs enable multiple discrete signal connections
• Four relay outputs deliver switching with 0.3A output current
• Single Ethernet port allows networked communication and integration
• Battery backup preserves configuration and runtime state
• Operates down to -20°C supporting cold-environment use
• Rated to 55°C for sustained higher-temperature performance

• Suitable for local control in factory automation panels
• Used for remote monitoring via Ethernet networks
• Ideal for simple building automation switching tasks
• Can be used for signal consolidation from field sensors
• Used with relay loads requiring sub-1A switching capacity

The unit provides one Ethernet communications port for network connectivity.

It is intended for DIN-rail mounting to fit standard control enclosures.

The device accepts eight digital inputs and provides four relay outputs.

The permissible operating range spans from -20°C up to 55°C.

The product carries CE approval indicating conformity with applicable Directives.
