Because mechanical relays have limited lifetimes, mechanical KYZ relays are typically not suitable for
energy pulsing applications. For energy pulsing applications, consider using Form A outputs in KYZ
mode.

A typical connection and operational details are illustrated below..

The mechanical relays should be protected by external fuses.

Solid-State Relay Outputs

Specifications for the four digital relay (Form A) outputs (D1 through D4) are as 
follows:

Digital output D4 is configured at the factory to emit pulses for calibration testing purposes.
