GENERAL SPECIFICATIONS (CONT'D)
3. MEMORY: Non-volatile memory retains all programmable parameters. RD500
also stores the parameters in order to reprogram modules that are replaced.
4. ISOLATION LEVEL: 500 Vrms @ 50/60 Hz for 1 minute between the Signal Inputs
and the RD500 Power Supply Input.
5. COMMUNICATIONS: Provided by the RD500
6. CERTIFICATIONS AND COMPLIANCES:
