Siemens RDH Series Thermostat, IP20, 5A Maximum Current - RDH100 / S55770-T377

This thermostat is a wall-mounted controller designed for precise temperature regulation in industrial and building automation environments. It presents setpoint and status information on an LCD and uses closed-loop control to manage a single relay output, making it suitable for managing simple heating or cooling loops within defined ambient ranges.

Features and Benefits:

• PID control delivers stable temperature regulation and reduced oscillation
• Relay output rated 5A enables direct switching of compatible loads
• Operates from 3V up to 250V AC for flexible supply arrangements
• Single input supports straightforward sensing and control tasks
• IP20 enclosure allows installation in protected indoor panels

Applications

• Suitable for HVAC zone temperature control panels
• Ideal for industrial process cabinets with simple on/off loads
• Used for temperature management in electrical enclosures
• Can be used for small heating device control in workshops

What ambient range can I expect for reliable operation?

The unit functions correctly between +5°C and +30°C, so ambient temperatures should be maintained within that span to ensure proper control behaviour.

How many outputs are available and what type are they?

There is one output provided, implemented as a relay suitable for switching up to 5A of load.

What mounting method is required for installation?

It is designed for wall mounting and should be fixed to a suitable indoor surface or panel.
