1582-13, -14 Data Switches

  

The 1582-13 Data Switch provides Auto, Manual, or Remote relay switching between CH1 and CH2 data signals (RS232C or RS422) on pins 3 and 8 with pin 5 ground and the other pins of the DB9 connectors tied together. Alarm conditions are either if clock is lost for a preset 0.1 to 0.9 seconds on CH1 and CH2 or a contact closure. Switching logic can be selected as follows:

1) CH1 Prime Mode - Switches from CH1 to the CH2 only if CH1 alarms and CH2 is good. Switches back to CH1 when it is no longer in alarm or when both CH1 and CH2 are in alarm.
2) Latch to CH2 Mode - Switches from CH1 to CH2 if CH1 alarms and CH2 is good. Latches to CH2. Push Reset or ground Remote Reset pin to return to CH1 if it has no alarm or both CH1 and CH2 are in alarm.
3) Minimum Auto switching, Initial Channel Select (ICS) Mode - Switch stays on channel last selected by Manual or Remote selection after return to Auto if both channel alarms are clear or both channels are in alarm. Auto switching occurs only if current channel alarms and the other channel is clear.

When power is applied with no alarms, CH1 is selected. On power loss CH1 is the selected. The Manual Select switch and contact closures to Remote Select pins (when in Auto), select CH1 or CH2 independent of alarms. LEDs indicate alarm and switch conditions for CH1 and CH2, REMOTE or MANUAL operation, and power on. Data connectors are DB9, female. Contact closure I/O’s are via barrier strip. Dual power supplies provide redundant power. The 1582-14 Data Switch has two independent switches (A and B) in one 1 3/4” chassis.
