Just 12 mm wide, the PTC module features eight channels to connect PTC thermistors according to DIN 44081 and DIN 44082 for thermal monitoring (overload protection) of motors, machinery, bearings, etc.
Up to six PTC thermistors can be connected in series per channel. If the nominal response temperature (ϑnat) is exceeded, a bit is set in the module's input process image. In addition, wire breaks and short circuits are monitored for each channel. If an error occurs, a bit is also set in the input process image. One green and one red status LED per channel indicate overtemperature or wiring errors.
Field and system levels are electrically isolated.
An operating tool with a 2.5 mm blade (210-719) is required to open the CAGE CLAMP® S connections.
