Model 242 DC Isolator

PublishTime：2024-09-05

●General: 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.
●The Reno A&E Model 242 is optically isolated from the input using an Opto-isolator. 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.
■Exceeds CALTRAN TEES Standards
■AC line input voltage: 89 VAC to 135 VAC, 50/60Hz
■AC Input Power: ≤2.5W (max)
■AC input - fuse protected
■I/O Insulation: ≥1000 Megaohms
■I/O Isolation Voltage: ≥3000VAC RMS
■Channel Output to Controller: Open Collector
■Output Time: 100 msec minimum hang time for call
■Fault Detection and Indication for each channel
■Connector: 2 x 22 contact card edge connector with a 0.0156-inch contact center with keyed slots.
■Operating Temperature: –40℃ to +85℃
