MULTICAL® 402
9 Plug-in modules
MULTICAL® 402 can be extended by a wide range of extra functions if plug-in
modules are added. The individual modules are briefly described below.
9.1 Pulse inputs
Pulse inputs (VA) and (VB) are used
for connection of extra water meters
with either Reed-switch output or
passive electronic pulse output. Min.
pulse duration is 30 ms. and max.
pulse frequency is 0.5 Hz.
65 +
(VA) Pulse input
66 -
67 +
(VB) Pulse input
68 -
If a module with pulse inputs is mounted in MULTICAL® 402, the meter will
automatically be configured for pulse inputs.
Please note that the pulse figure (litres/pulse) must match 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.
9.2 Pulse outputs
Pulse outputs for energy (CE)
and volume (CV) have Darlington
optocouplers and are available with
many of the plug-in modules. Max.
voltage and current are 30 VDC and
10 mA.
16 +
(CE) Pulse output for energy
17 -
18 +
(CV) Pulse output for volume
19 -
If a module with pulse inputs is mounted in MULTICAL® 402, the meter will
automatically be configured for pulse inputs. The pulse duration was 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 digit
displayed for energy and volume respectively.
