Product Pulse Input Module SFC467

The following pulse input modules are available:

• SFC441 (2 Groups of 8 inputs of 24 VDC for low speed pulse counting - sink)
• SFC442 (2 Groups of 8 inputs of 24 VDC for high speed pulse counting - sink)
• SFC467 (2 Groups of 8 inputs of 24 VAC for high speed pulse counting - sink)

 

The modules have 2 groups of 8 inputs to count and accumulate pulses until the Field Controller reads them. Immediately after it is read, every individual counter is cleared and the hardware begins to count again, ensuring that no pulses are lost during the acquisition process. An associated PULSE Function Block has been specifically designed to take advantage of this module. For details see the Function Block manual.

 

• SFC441 can be driven by a mechanical contact of a relay or reed-switch. A single pole internal filter has the cutting frequency in approximately 200 Hz
• SFC442 is for higher frequency sources that do not generate bouncing on level switching.
• SFC467 is for higher frequency AC sources

In order to feed conventional analog, discrete and pulse signals into the control system and to

provide facilities for controlling valves, starters, pumps, switches etc., a number of local I/O

modules can be added to the Field Controller rack assembly.

 

The modules are addressed by means of a channel number in a special Field Controller hardware

transducer block and, depending upon type and function, connected to the fielbus system by means

of multiple or standard input and output blocks. Depending upon I/O type, an Analog or Discrete

Multiple function block provides a connection for up to 16 input or output signals.
