1.3 4092A Overview

The TSC 4092A IRIG-B Autosense Fault Switch is a 1U (1.75") high, 19-inch, rack-mount, autosense, fault switch that accepts two IRIG-B inputs and produces eight outputs (chosen from the two inputs). The unit can be configured with redundant hot swappable AC or DC power supplies. The TSC 4092A can also be configured to accept two 1-200 kHz sinewave signals but traditionally would be used as an IRIG-B Fault Switch.

The front panel provides green/red LED status for the inputs and for all output signals, as well as indicating the active input signal. A green/red LED on the front panel also provides power status. The front panel also has a locking toggle control switch that you can use to manually switch between input signals or to configure the unit to switch automatically upon input signal failure.

An Ethernet port on the rear panel provides the capability to remotely monitor the status of the power supplies, input, and all output signals. Any failure in the unit will immediately provide an alarm to this port.
