USER MANUAL – Z-SG
6
Response time (10%-
90%)
5ms
Voltage-type OUT
Output scale range configurable between: 0..5V or 0..10V by Dip-
Switches. Minimum resistance that can be connected: 2 k
Current-type OUT
Output scale range configurable between: 0..20mA or 4..20mA by
Dip-Switches. Max resistance that can be connected: 500
LOAD CELLS
A load cell or more load cells (if they are parallel-connected) can be connected to the Z-SG
module.
Load impedance
Minimum impedance that can be connected: 87
. This value can
be equivalent impedance of more parallel-connected load cells.
For example: up to 4 load cells (if each cell has input impedance:
350
), up to 8 load cells (if each cell has input impedance: 1000
)
Cell sensitivity
Configurable between: ±1mV/V; ±2mV/V; ±4mV/V; ±8mV/V;
±16mV/V; ±32mV/V; ±64mV/V by Dip-Switches.
From +-1mV to virtually infinity from Modbus Registers.
Internal load cell
voltage supply
the #7 screw terminal (+Excitation) powers 5Vdc with reference to
the #10 screw terminal (-Excitation). The #8 screw terminal
(+Sense) reads “+Excitation”, the #11 screw terminal (-Sense)
reads “-Excitation”
CONNECTIONS
RS485 interface
IDC10 connector
RS232 interface
Jack stereo 3.5mm connector: plugs into COMport
PROTECTION
This module provides inputs protection against the ESD (up to 4kV)
for every screw terminals
1500 Vac ISOLATIONS
Between: power supply, ModBUS RS485 and analog output, analog
input, digital input/output
