Pulse interface
During test and verification of MULTICAL
801, where high-resolution energy pulses are required verification
adapter type 66-99-461, placed as module 1, can be used.
The pulse interface collects serial data from MULTICAL
801 every 7 s and converts these high-resolution data to
high-resolution energy pulses with the same resolution as the high-resolution register of the display (see section
12.1)
The pulse interface must be voltage supplied on terminals 97-98 from en external supply with 5…30 VDC and the
current consumption is max. 5 mA. You might use MULTICAL
801’s auxiliary supply on terminals 97A and 98A.
The high-resolution energy pulses are transmitted as an open collector signal on terminals 13-12, whereas an
internal pull-up resistance of 10 kOhm can be connected to the external pulse supply via terminal 13A.
