MULTICAL® 602 & ULTRAFLOW®
9.2 Bse modules
9.2.1 Dt + pulse inputs, type 67-00-10
The dt terminls re used for connection of
e.g.  PC. The signl is pssive nd glvniclly
seprted by mens of optocouplers.
Conversion into RS232 level requires
connection of dt cble 66-99-106 (D-Sub
9F) or 66-99-098 (USB) using the following
connections:
62 Brown (DAT)
63 White (REQ)
64 Green (GND)
The pulse inputs cn be used for connection of electricity nd wter meters.
Plese py ttention to mximum pulse frequency s well s correct pulse coding (l/imp. nd
Wh/imp.), which is selected by mens of the FF nd GG configurtion.
65 - 66 Input A
67 - 68 Input B
9.2.2 M-Bus + pulse inputs, type 67-00-20/27/28/29
M-Bus cn be mounted in str, ring or bus topology. Up to 250 meters cn be connected
depending on the M-Bus Mster’s power supply nd the totl cble resistnce.
Cble resistnce < 29 Ohm
Cble cpcity < 180 nF
The M-Bus network is connected on terminls
24 nd 25. The polrity is unimportnt.
M-Bus comes with pulse inputs.
