SICS Scale Base
The IND780 supports Mettler Toledo high precision scales and balances that utilize the SICS
communications protocol. These scales and balances are branded as the Mettler Toledo Excellence
balances, X-bases/platforms, WM/WMH and 4-series scales (BBx4xx, IND4xx). The SICS scales
are connected to the IND780 via the serial interfaces. Four SICS scales can be supported per
terminal, when optional Serial boards are installed. Depending on the type of SICS scale connected,
different configuration settings will be available in the IND780 terminal setup screens.

POWERCELL
The IND780 supports scales that use the POWERCELL MTX communications network found in large
hopper / tank applications as well as vehicle scales that use the MTX load cell. This interface also
supports the use of the RAAD Box, which converts analog load cell signals into digital ones.
1.9.5.
POWERCELL
The IND780 supports scales that use the POWERCELL PDX communications network, typically
found in vehicle scale and large tank weighing applications that use the PDX load cell. When used
with an external power supply, the IND780 PDX interface can support as many as 24 cells. Up to
four independent scale bases can be logically addressed by the terminal. When used in
combination with a PDX network, the IND780 provides several diagnostic features such as
predictive failure, automated alerts and cell performance monitoring. These features help lower
maintenance costs and minimize downtime.

Flow Meter Interface
The Flow Meter Interface Board is a two-channel isolated Counter/Flow Meter board for use in the
IND780batch terminal. It is intended to provide a flow-meter totalizer target comparison to directly
control on-board discrete outputs. The module is capable of counting input pulses at up to 50 kHz
on each of two isolated input channels, as well as measuring the frequency of the input signal. A
jumper-selectable switching threshold for each input channel is available, as well as a jumper-
selectable 15 kHz analog filter. The input level range for the AC mode is 50mV to 50Vrms. The
input level range for DC mode is 2.5 volts to 42 volts.
The outputs are 7407 open-collector drivers. Each module provides 150 mA of 5V power to drive
opto-22 or similar devices. A total of two flow meters may be connected to a single flow meter
card. Each terminal can connect to as many as 4 flow meters.
