WEG Automation RPW PTC Relay.
Size: 22.5mm Wide x 85.5mm Deep x 104.77mm.
Enclosure Rating: IP20.
Mounting: Directly to a backplate via two 4.8mm holes on 91.3mm fixing centres, or fitting to 35mm DIN Rail.
Voltage: 24V to 240V ac/dc
Function: The RPW-PTC relay has status indication through the LEDs located on the front of the product. The green LED is ON when the relay is energized. If the monitored temperature by the PTC is below the defined value of 3.5 kΩ, the red LED will be ON indicating normal operation. Therefore, if the resistance exceeds the limit of 3.5 kΩ, the relay will instantaneously switch the output contacts and the red LED will be OFF indicating an over temperature condition of the motor. The relay will only switch on the 15 and 18 contacts again once the temperature goes down to normal values.
Additionally, the WEG PTC relay provides sensor testing feature.In case of failure of the PTC sensors, the green LED will be FLASHING. This feature indicates that the PTC sensors are either open or in short circuit (20ohms or less).
Part Number: 10075636 (RPW-PTC-E05, RPW-PTCE05 or RPWPTCE05)
