Siemens RDJ Series Room Thermostat, 5A Maximum Current, 250V AC Maximum Voltage - RDJ100 / S55770-T379
This room thermostat is a Compact wall-mounted controller designed to regulate ambient temperature in commercial and industrial settings. It presents a clear LCD for setpoint monitoring and uses a control algorithm suited to maintain stable conditions. The device operates on common AC supplies and switches loads via an internal relay, making it appropriate for integration into building automation and equipment cabinets where straightforward temperature control is required.
Features and Benefits:
• PID control ensures steady temperature regulation and reduced cycling
• Relay output supports switching up to 5A for external loads
• LCD provides instant Visual feedback for user adjustments
• Screw terminals enable secure wiring and straightforward installation
• IP20 enclosure permits indoor use in protected locations
• Relay output supports switching up to 5A for external loads
• LCD provides instant Visual feedback for user adjustments
• Screw terminals enable secure wiring and straightforward installation
• IP20 enclosure permits indoor use in protected locations
Applications
• Suitable for HVAC control in commercial plant rooms
• Ideal for temperature regulation of electrical enclosures
• Used with heating actuators and small fans in commercial spaces
• Can be used for process temperature monitoring in machinery rooms
