9: External I/O Modules
9.8: Digital Solid State Pulse Output (KYZ) Module
9.8.1: Overview
The KYZ Pulse Output Modules have 4 KYZ Pulse Outputs and accept Read and Write
Commands with at least 4 registers of data per command. Digital Solid State Pulse
Output (KYZ) Modules are user programmed to reflect VAR-hours, Watt-hours, or
VA-hours. See the Modbus Communicating I/O Modules User Manual for details on
programming the module.
The Nexus® 1250/1252 meter supplies power for up to 4 connected KYZ Pulse Output
modules. See Section 9.2 for power and communication details. Refer to Section 5.6.2
to determine if you must use an additional power source, such as EIG’s PSIO.
