90 Á with diagnostic LEDs , screw terminals. The PROFIBUS connector 90 Á with diagnostic LEDs is equipped with proven and reliable screw terminals. The connector is quickly mounted and has integrated, connectable terminating resistors. The housing is metallized for improved electromagnetic compatibility. The PROFIBUS diagnostic connector can be used to connect a PROFIBUS network in which the user can check the status of the bus system at any time at a glance. The three built-in LEDs with the easily distinguished colors blue, green and orange indicate the most important states of the PROFIBUS network at each station. The state of the terminating resistor (orange), whether bus activity is in progress (green) and whether the station addressed is participating in bus traffic (blue) are all indicated. This means errors, such as bus interruptions, missing or incorrectly connected terminating resistors and malfunctioning or failed bus stations can be detected immediately. The PROFIBUS connector also works in the extended ambient temperature range of -25 ÁC to +85 ÁC*. Features: 3 status LEDs indicate bus operation station transmitting terminating resistor inserted. Metalized housing. Integrated switchable terminating resistor. 90 Á cable outlet. Screw terminals.
