Specications–ChargeRegulatorand 
AUX Output
A charge regulator and AUX output are included
on the Processor/Main Electronics board. Please
note that this charge regulator is sized for
ControlWave GFC, not ControlWave GFC Plus.
Solar panels of 10-watt or higher capacity must
use external regulators.
Input Voltage Range: 5.0 to 18.0 Vdc•
Operating Range: 4.5/4.9V to 18.0V, shutdown •
occurs at 4.3V nominal (6V power source);
10.3V to 18.0V, shutdown occurs at 9.56V
nominal.
Fuses: 1.5 A from charge regulator, 3.5 A for •
battery input.
Surge Suppression: 18VDC transorb meets •
ANSI/IEEE C37.90-1978.
Terminations: Pluggable terminal block, max •
wire size is 16 gauge
Charge regulator: Temperature-compensated •
charge control with cut-off
Threshold voltage for shunt at 23ºC: 7.3V for a •
6V battery and 14.6V for a 12V battery
AUX Output Max Load Current: 1.8 A •
continuous, 2.5 A momentary
AUX Output “on” Resistance: 0.37 Ohms •
typical, 0.5 Ohms max
HAZARDOUS AREA CERTIFICATION
Class I, Division 2 certication can be specied.
ControlWave GFC Plus is approved by UL as an in-
strument. Note that this certication strictly prohib-
its installation of any other hardware, not indicated
by the model number, in the instrument enclosure.
Wiring to and from the I/O, communication and
power connections inside the enclosure, per the
ControlWave GFC Plus manual, are, of course, al-
lowed.
BENDABLE RTD
You can choose a bendable RTD that is attached
to the ControlWave GFC Plus via an armored cable
of 6-foot, 15-foot or 25-foot length. The individual
wires attach to a terminal block on the Processor/
Main Electronics board. The terminal block accepts
up to three wires.
Normally, this RTD would be used to provide the
process temperature input but the standard ap-
plication program also allows the user to select an
external temperature transmitter, instead.
The bendable RTD is a “one size ts all” solution
that is perfect for most applications and excellent for
depot-level inventory situations in which the ultimate
installation (and, therefore, thermowell depth) is not
necessarily known.
The 12” probe can quickly be inserted in a
thermowell, whereupon the user can tighten the in-
cluded tting to lock it in place and bend the excess
length out of the way. Note that a thermowell is
required for this bendable RTD!
