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.

Nexus 1250/1252 Unit supplies power for up to 4 connected KYZ Pulse Output modules. See section 9.2 for power and communication details. Refer to sections 5.12 - 5.13 to determine if you must use an additonal power source, such as the EIG PSIO.

The Modbus Map for the KYZ Pulse Output Module (and operating details) can be found in the Modbus Communicating I/O Modules Manual.

NC = Normally Closed; NO = Normally Open; C = Common.
