1582-03, -04 Data Switches

  
The 1582-03 detects presence of data on a main (Data 1) and secondary (Data 2) data channel by detecting positive level transitions on both inputs. If no data is detected on the Data 1 channel for 1 to 9 minutes (adjustable in 1 minute increments), an alarm will occur causing the switch to transfer the Data 2 channel to the SELECTED DATA output. If the Data 2 channel also has an alarm, no switching will occur or switching can always be forced to the Data 2 channel. After switching to the Data 2 channel, when the Data 1 channel alarm clears the switch transfers data back to the Data 1 channel. Switching is accomplished using a relay so if power is removed from the 1582-03, there is signal continuity from the Data 1 channel to the SELECTED DATA output. Front panel LEDs indicate alarm conditions for the Data 1 and the Data 2 channels. The channels can be manually switched via a front panel switch. Dual switching power supplies provide redundant power to the 1582-03. The unit is housed in a 1 3/4”, rack mount chassis. The 1582-04 is a dual version of the 1582-03 and contains two independent switches in a 1 3/4” chassis.
