Configurable Relay Outputs
Each module has 3 configurable Relay Outputs. Each relay output can be
configured to reflect the state of any Boolean value within the module. Each
output can be configured to be inverting or non-inverting. If configured as
non-inverting, the relay will energize when the configured input is true. The first
configurable relay is defaulted to the output of the Alarm Latch.

Analog Output
A single 4–20 mA output is provided on each module to indicate the speed
sensed by that module. The 4–20 mA range can be configured to any speed
range desired. The accuracy of the analog output is better than ±0.5% of 20 mA
over the temperature range of the product.
Shielded twisted pair cable is required when connecting to the analog outputs.
