9. Plug-in modules
A number of extra functions can be added to MULTICAL® 402 by means
of plug-in modules. The individual modules are briefly described below.
9.1 Pulse inputs
Pulse inputs (VA) and (VB) are used for the connection of extra water
meters with either Reed switch output or passive electronic pulse
output. Min. pulse duration is 30 msec. and max. pulse frequency is 0.5
Hz.
If a module with pulse inputs is mounted in MULTICAL® 402, the meter
is automatically configured for pulse inputs.
Please note that the pulse figure (litres/pulse) must match between the
extra water meters and the configuration of VA and VB. After delivery the
configuration of VA and VB (config FF and GG) can be changed by means
of the PC program METERTOOL.
65 +
(VA) Pulse input
66 -
67 +
(VB) Pulse input
68 -
9.2 Pulse outputs
Pulse outputs for energy (CE) and volume (CV) are designed with
darlington optocouplers and are available with many of the plug-in
modules. Max. voltage and current is 30 VDC and 10 mA.
If a module with pulse outputs is mounted in MULTICAL® 402, the meter
is automatically configured for pulse outputs. The pulse duration is
ordered at 32 msec. or 0.1 sec. After delivery the pulse duration can be
changed by means of the PC program METERTOOL.
The resolutions of the pulse outputs always follow the least significant
digits of energy and volume respectively in the display.
