Siemens RDJ Series Thermostat, IP20, Relay Output Type - RDJ100RF/SET / S55770-T380
This thermostat is a wall-mounted control device designed to regulate room temperature within a narrow operational range. It provides on/off switching via a single relay output and presents setpoint and status information on an LCD, making it suitable for building automation and equipment where simple, accurate temperature control is required.
Features and Benefits:
• Relay output rated for 8 A supporting mains switching
• Operates from low-voltage 3V DC supply for safe integration
• PID control algorithm enabling precise temperature regulation
• Screw-terminal connections allowing secure field wiring
• IP20 enclosure suited to protected indoor installations
• Operates from low-voltage 3V DC supply for safe integration
• PID control algorithm enabling precise temperature regulation
• Screw-terminal connections allowing secure field wiring
• IP20 enclosure suited to protected indoor installations
Applications
• Suitable for HVAC zone temperature control in plant rooms
• Used for environmental control in electrical enclosures
• Ideal for integration with building automation panels
• Can be used for temperature regulation in industrial cabinetry
• Used for environmental control in electrical enclosures
• Ideal for integration with building automation panels
• Can be used for temperature regulation in industrial cabinetry
What temperature range can it control reliably?
It is intended to manage environments between +5 °C and +30 °C, matching typical indoor climate requirements.
How is the device mounted and connected on site?
It fits to a wall-mount position and uses screw terminals for the single output and supply connections, simplifying installation.
What standards approvals does it have for regulatory acceptance?
It carries CE, EAC and UKCA approvals indicating conformity with relevant regional requirements.
What operating temperatures will affect its performance limits?
The unit is specified for use up to a maximum ambient of +30 °C, with a lower operational limit of +5 °C.
What output and voltage constraints should installers note?
The relay output is capable of switching up to 250V AC at a maximum current of 8 A, and the control electronics operate from a 3V DC supply.
