GENERAL DESCRIPTION

The Model GMSG is a full featured single loop PID controller
designed for use with the Graphite products. The module accepts
low level signals from a variety of bridge-type transducers, such
as load cells, pressure transducers, torque transducers, etc. An
optional second signal input is available, providing math
capabilities between the two input channels (average, differential,
etc.). Each input channel provides a software selectable 5 V or 10
V stable bridge excitation voltage, capable of driving up to four
350 W bridges (combined total per module). The inputs are
selectable for ±20 mV, ±33 mV, or ±200 mV full scale. With solid
state or relay outputs, plus an analog output, the GMSG module
can perform virtually any combination of time-proportioning or
linear control. The discrete outputs may also be assigned to one
of seven internal soft alarms; and the linear output can be
assigned to transmit virtually any internal variable. In addition,
digital tare (re-zero), batch totalizer, and peak/valley (max/min)
are provided.
The modules connect and communicate via proprietary USB
connection to the various Graphite host devices. Those devices,

equipped with serial ports as well as Ethernet port(s), allows the
system to share data with PCs, PLCs, and SCADA systems.
Caution should be used when adding modules to Graphite.
Some modules, depending on usage, may consume high levels of
power. This may limit the total number of modules that can be
installed on a single Graphite host. Check the Graphite module
and Graphite host data sheets for specific usage and power
requirements.
The GMSG modules are available with relays, or open drain
MOSFET outputs. For applications requiring large loads to be
controlled, several DIN rail mount relays are available.
The modules can operate in On/Off, P, PI, or PID control mode,
and use an on-demand Auto-Tune that establishes the tuning
constants. The PID constants may be fine-tuned through the
serial or Ethernet interface. The modules employ a unique
overshoot suppression feature, which allows the quickest
response without excessive overshoot. The modules can also be
operated in manual mode, providing the operator with direct
control of the output.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that
appear in this document or on equipment must be observed to
ensure personal safety and to prevent damage to either the
device or equipment connected to it.
Do not use these products to replace proper safety interlocking.
