Faraday Switch Modules    Under development --- Available Soon

Remote Touch Switch Sensor:  This tiny 3/8 inch square module is  designed to be wired to a metal touch button or to a metal touch plate. Powered by a special signal from an Exciter/Interface module, the sensors can be separated from the control module by several hundred feet. These sensors are ideal for applications where multiple and widely separated touch buttons need to be monitored. The sensors can also be connected in parallel, forming an "or" logic function. Such a technique allows multiple switches in several locations to activate a single control function.

Exciter/Interface Module:  This module is designed to be used with up to 24 touch sensors. It supplies the remote touch sensors with a special signal and processes the outputs from the touch sensors. It operates in a momentary switch operation. Each module has 24 inputs and 24 outputs. All the outputs are standard TTL logic levels which can source or sink current. The outputs can be programmed for a normally high or a normally low. A single programming pin selects the polarity. The exciter/interface module can be installed several hundred feet from the touch sensors it supports.

24 Button Touch Switch Control Module:   This module is designed to be used with up to 24 touch buttons or touch plates. It is ideal when the touch buttons or plates can be clustered around and near the control module. The separation distance between the touch buttons and the modules should not exceed 6 feet. As in the Exciter/Interface module the Control module has 24 inputs and 24 outputs. All the outputs are TTL levels and can be programmed for a normally high or a normally low. A single programming pin selects the desired polarity.
