ABB PFSK 163 3BSE016323R3 Channel contact module

Two adjustable limit values, within the same full scale range, are available for signalling alarms. To prevent the alarm relays being activated by shortterm high vibration levels which exceed the alarm values, a time delay can be activated for each individual alarm relay. Limit value exceedances are displayed on the VIBROCONTROL 920 by alarm LEDs while the exceedances can be signalled further using the respective potential-free alarm relay contacts. Setting up of the instrument for the measurement and monitoring task is done by means of setup parameters.

OK Monitoring 

Self-monitoring of the power supply, the internal microprocessor system as well as the sensor status is done by the OK monitoring system. An existing OK error is displayed by an LED and signalled by the changeover of potential-free contacts of the OK relay. In the case of a fault the lightemitting diode will go off and the contacts of the corresponding relay will change over A diagnosis output (terminals B / ↓) is available for checking purposes and enables analysis of the input signal with correct phase. All cable connections to the instrument are made by means of screw terminals.
