Customer Interface Device

CID-1

The SSI CID-1 Customer Interface Device is a low-cost, fused KYZ termination device designed to supplement the electric meter’s KYZ pulse initiator. It provides two sets of KYZ connector terminals — one for the meter’s K, Y, and Z output terminals and one for the utility customer’s energy control system input — in a single compact, watertight enclosure. It is the simplest and most direct way to provide a clean, fused, protected KYZ connection between a utility meter and a customer-owned system.

The CID-1 is housed in a watertight Noryl enclosure with a beaded-gasket lid that keeps the internal circuitry clean and dry. Four conduit knockouts for ½” electrical conduit support a wide range of mounting and connection configurations to the meter enclosure. Euro-type terminal strips ensure no exposed conductors are present when wired, providing maximum protection from accidental shock.

Product Highlights

The CID-1’s coordinated fusing scheme places the K fuse and either the Y or Z fuse in series at all times, protecting both the meter and the customer’s energy control system from overcurrent, incorrect wiring, and fault conditions. This configuration also supports master/slave fusing arrangements. A built-in snubber network suppresses excessive transient voltages without requiring external suppressors.

With a maximum voltage rating of 250VAC/VDC and an input/output resistance of just 50 milliohms, the CID-1 introduces negligible resistance into the metering circuit while providing meaningful protection at a minimal cost.

Features

The SSI CID-1 is a single-channel fused KYZ termination device bridging a utility meter's pulse output to a customer energy control system in a watertight Noryl enclosure.
  • Single-channel KYZ termination — provides two sets of K, Y, Z connector terminals for meter input and customer equipment output.
  • Coordinated series fusing — K fuse in series with Y or Z fuse at all times; protects meter and customer equipment from overcurrent and wiring faults.
  • 250VAC/VDC maximum voltage — rated for standard utility metering voltage levels.
  • 50 milliohm input/output resistance — negligible circuit resistance preserves pulse signal integrity.
  • Built-in snubber network — suppresses transient voltages without requiring external surge devices.
  • Watertight Noryl enclosure — beaded-gasket lid keeps circuitry clean and dry; excellent electrical insulation.
  • Four ½" conduit knockouts — supports flexible mounting and connection to meter enclosures in a wide range of configurations.
