VBA-4E4A-G20-ZEJ/M3L-P9 320725 Pepperl+Fuchs Module

The AS-Interface connecting module is a field module with two sensor inputs and two electronic outputs for controlling DC roller motors of the type Interroll EC310 and Rulmeca BL3 or compatible. The compact housing can be installed directly into support profiles or cable ducts. It is connected to the AS-Interface network and the auxiliary energy using insulation piercing technology via the AS-Interface flat cable. The swiveling flat cable guide is locked without the use of tools. The sensor inputs and motor outputs are connected using cable outputs with M8 round plug connectors. The inputs are supplied via the AS-Interface. The motors are supplied via the external auxiliary voltage U AUX. The current switching state of the sensor inputs, the presence of supply voltage at the motors, the operating state of the motors (stationary/in operation), the direction of rotation, and the setting of the fault signal via a motor is displayed via LEDs. Using AS-Interface data bits, the motors can be switched on or off individually, the direction of rotation can be changed, and the speed of the motor can be controlled. The voltage for the speed signal and a separate direction of rotation for motor 2 can be controlled via AS-Interface parameters. To control the acceleration and to stop the motors, a start/stop ramp can be set for the speed signal. The time period of the ramp can be selected from eight preset values and can be configured. Once selected, the ramp is stored in non-volatile memory and automatically activated after each switch-on. The ramp is not effective if the direction of rotation signal is switched when the motor is running. In this case, the direction of rotation is reversed immediately. Note: The communication monitor of the module deactivates the outputs if the AS-Interface does not communicate with the module for more than 40 ms. Inputs IN1 and IN2 suppress pulses that are shorter than 2 ms. An overload of the input supply, an overload of the speed signal, or a lack of external auxiliary voltage is reported to the AS-Interface master. The communication via AS-Interface remains unaffected.
