9.8.1: Overview
Q 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.
Q 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.
Q The Modbus Map for the KYZ Pulse Output Module (and operating details) can be found in the
Modbus Communicating I/O Modules Manual.
Q NC = Normally Closed; NO = Normally Open; C = Common.
