Fieldbus Terminal Controller GEL 8500

General
Optimised for the rough environment, the fieldbus terminal controller GEL 8500 meets all Cold Climate Version (CCV) and Hot Climate Version (HCV) requirements arising in all today's fields of application like wind turbines or rail vehicles. The fieldbus terminal controller for the extended temperature range GEL 8500 is a CANopen enabled remote module with six digital inputs and outputs, as well as four PT100 inputs. As a special feature, two 230 VAC switched outputs are integrated. The fieldbus interface is designed as a CANopen slave in accordance with CiA Draft Standard DS302 and DS401. The vertical design, and thus minimum space requirement on the top hat rail, makes the fieldbus terminal controller ideal for decentralised solutions. The fieldbus terminal controller is mounted on a standard top hat rail. The signal connection level has been developed for permanent wiring with connector strips. Multicolour light diodes on the front provide information on power supply, device status as well as fieldbus status of the equipment. In addition to the flexible and decentralised extension of I/O for controls and frequency converters, the fieldbus terminal GEL 8500 can also decentralise functions in your machine thanks to sufficient computing power.
