3.2.5. Failsafe Alarm Relay Wiring and Specifications
The “Failsafe” output relay is provided to signal critical error conditions that may occur on RS2000
series products. The contacts are energized upon power-up of the unit and remain energized
unless a critical error occurs. The proper relay connections are shown in the figure below. Control
of this output is user selectable and can be programmed via the Rugged Operating System (ROS).
One common application for this output is to signal an alarm if a power failure or removal of control
power occurs.

access to the management console. The connection is made using the DB9-Female to RJ45
console cable included in the device packaging shown in
Figure 3.23, “RS2000 Series Console
Cable” . Console connection settings are: 57600 bps, no parity bits, 8 data bits, and 1 stop bit.
