Frequently Asked Questions

The default configuration and alarm set for the RELAYIOCARD are: - Relay 1 - Summary Alarm - Any additional alarms that a compatible UPS provides outside of the preset contact alarm of relays 2-6 below. - Relay 2 - Power Fail - Input power to the UPS is lost and the UPS is On Battery. This can also be triggered by voltage and/or frequency out-of-range, or self-test operation. - Relay 3 - Battery Low – UPS battery system is nearly depleted. - Relay 4 - On Bypass – This alarm can occur for a number of reasons and is UPS-specific. See your UPS Owner’s Manual for reported bypass conditions. - Relay 5 - Overload – The connected load is drawing more power than the rated capacity of the UPS. - Relay 6 - Over Temperature - The UPS system’s internal temperature has exceeded its set threshold. Note: You can receive one or more contact alarms at the same time depending upon the available feature set from your UPS system.
The RELAYIOCARD can be configured through a terminal program like HyperTerminal or Putty. Use the included serial cable, which connects to the TX and RX, and GND-C ports of the terminal strip.
The terminal strip is screw type. The terminals accept wire gauges from 22-16 AWG.
