ControlByWeb devices.
1.2 The X-16s Connectors & Indicators
Analog Inputs
The X-16s has eight analog inputs. Four analog ground (Agnd) terminals provide convenient connection
points for making sensor wiring connections. The X-16s can be setup to input either eight single-ended
analog signals, four differential analog signals, or a combination both.
Reference Output
Two 5.0V reference terminals can be used to power resistance sensing sensors such as potentiometers
and bridge sensors. The reference output can provide up to 50ma (the two reference terminals are
connected together internally). When resistance sensors are excited (powered) from the 5.0V reference
output, the measurement will be ratio-metric with the reference. With ratio-metric measurements the
absolute voltage (and error) of the reference is removed from the measurement accuracy.
Expansion Bus
The expansion bus allows for a family of expansion modules to be connected directly to the X-600M
without the need for an Ethernet switch. The cable can be a daisy chain with multiple connectors. The
ribbon cable expansion bus provides both power and communications connections.
Power Supply
The expansion bus can provide up to 1.7 Amps for powering up to 32 expansion modules; however, the
maximum number of expansion modules depends on the module type and power source attached to the
X-600M.
The X-16s employs modern switch-mode power supply. With this type of power supply the current draw
decreases as the voltage increases; therefore, you can add more expansion modules by using a 24-volt
