HERCULES
®
Low Voltage Contact Module
REASON TO USE A LOW VOLTAGE CONTACT MODULE:
This module is designed to interface any “120V output” to Air Conditioning/Heating “Low Voltage Control Inputs.”
Some Titan Controls
®
Controllers have “120V outputs” (eg. Apollo
®
series timer, Zephyr
®
series controllers, Eos
®
series controllers,
Atlas
®
series controllers … ). Should you need to control any SYSTEM whose inputs are not compatible with 120V output power,
you must use this module and refer to the connection diagram in the USER GUIDE of the SYSTEM you want to control.
ELECTRICAL SPECIFICATIONS:
Input: Low Power Coil - 120V AC 60HZ 0.4W
Output: Low Power Contact - 5A at 24V DC / 120V AC MAX.
• COM is the relay COMMON
• N.O. is the NORMALLY OPEN contact
• N.C. is the NORMALLY CLOSED contact
MECHANICAL SPECIFICATIONS:
Plastic enclosure dimensions: length 2 inches, width 1.5 inch,
depth 1 inch, prong length 0.65 inch
Terminal: thick Brass, Tin Plated
Screws: 6-32, length 0.25 inch

TYPICAL CONNECTION DIAGRAM:
Here is a typical connection diagram between
Hercules

Low Voltage Contact Module and any Air Conditioning System. Main
power to the A/C System is not shown here, only A/C control input terminals need to be connected to the

LOW VOLTAGE CONTROL INPUTS ON TYPICAL HEATING OR COOLING SYSTEM:
When using the
Hercules
®
, power lines to the SYSTEM, it must be connected directly to the building electrical box. Control inputs are
normally available on a SCREW TERMINAL BLOCK, each SYSTEM IN’s or OUT’s being identified by a letter. Typically, SYSTEM OUT
LINES will connect to the
Hercules
®
“COM” screw terminal and SYSTEM IN LINES to the
Hercules
®
‘’N.O.” screw terminal.
Typically, System OUTPUTS are connected to Hercules
®
“COM” screw terminal. Typically, System INPUTS are connected to Hercules
®
“N.O.” screw terminal.
