Programmable Contact Output Connections

Two types of programmable relays are offered with the 1133A: standard mechanical, Form-C
(SPDT) and optional solid-state, Form-C for use with KYZ pulse metering. Use protective measures
when using optional KYZ-rated contacts to guard against surges that will damage the contacts if
ratings are exceeded. See "Configuring Multimode Relays" in Section 7.10, for details on configuring
contacts.
