[DISCONTINUED] 242 DC Isolator

The Model 242 is designed to meet and exceed the specifications in Chapter 5, section 4, of the Caltrans Transportation Electrical Equipment specifications (TEES) dated 08/16/02. Section 4 specifies the requirements for a two channel DC isolator to provide isolation between a VDC input circuit (external electrical switch closure) and the controller unit input. T

he Reno A&E Model 242 is optically isolated from the input using an Optoisolator. Each isolated channel is equipped with a test switch that allows for a simulation of a valid input signal. Each channel has two light-emitting diodes (LED): a red LED (OUT) that indicates a call and a red LED (FAULT) that indicates fault status.
