EOTec 2000 fiber optic Multi-Channel Contact Closure modules convert up to 10 dry contact inputs to fiber optic signals for transmission over a single fiber optic link.
Upon activation of the inputs, the receiver module accepts the transmitted signals and de-energizes a corresponding on-board relay operating in a fail-safe mode for switching critical systems. Each transmit module includes 2 inputs and is capable of multiplexing up to 10 inputs by cascading additional dual channel input modules.
An integrated backplane allows for communications between modules with no external inter-module connection. Power to all the modules is derived from a standard EOTec 2000 power supply through the integrated BUS connector or from an external 24VDC source supplied directly to the transceiver module.
