Eastern Voltage Research was the first in the escape room industry to offer this type of human conductivity switch and as the original creator, we continually strive to improve our the functionality, quality, and reliability of our human chain controllers.  Our new line of human chain controllers feature improved detection and pre-amplifier circuits and also provide both a 10A relay output as well as a 3A solid state output channel to control almost any type of output device. We have tested this human chain controller with up to eight (8) people. 

Compatible Outputs:

Our controllers can be used with both 12VDC and 115VAC output devices.  The following is a partial list of output devices that can be used with our human chain controllers:

• Lights (LEDs, incandescent, halogen)
• Flicker LED controllers 
• UV Lights (perfect for revealing invisible ink clues and messages)
• Electromagnetic door locks
• Pneumatic switches and solenoids
• PLCs, external microcontroller circuits / devices
• External audio playback devices

Features:

• Operating voltage range:  12V nominal
• Intelligent microcontroller controlled
• Output 1 - Relay, SPDT (NO and NC) - Rated at 10A @ 277VAC (see safety note)
• Output 2 - Solid state - Rated at 3A @ 100V
• Three (3) LED status lights
• High quality removal terminal blocks
• Mounting holes for board mounting

Purchasing Options:

• Human Chain Controller 1.0 only
• Human Chain Controller 1.0 with 12VDC, 1A power adapter

Note:  An AC isolation transformer must be used for safety if using 115/230VAC power devices on the relay outputs.
