GE Grid Solutions Multilin 9450 - 9.8 Digital Solid State Pulse Output Module

CHAPTER 9: EXTERNAL I/O MODULES DIGITAL SOLID STATE PULSE OUTPUT (KYZ) MODULE
EPM 9450/9650 ADVANCED POWER QUALITY METERING SYSTEM – INSTRUCTION MANUAL 9–13
9.7.1 Overview
The Relay Output Module consists of four Latching Relay Outputs. In Normal Mode, the
device accepts commands to control the relays. Relay output modules are
triggered by limits programmed with the GE Communicator software. See the
GE Communicator Instruction Manual for details on programming limits.
The EPM 9450/9650 meter supplies power for up to 4 connected Relay 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 GE’s PSIO.
The Modbus Map for the Analog Output Module (and operating details) can be found in the
Modbus Communicating I/O Modules Manual.
Each latching relay will hold its state in the event of a power loss.
9.7.2 Communication
Maximum registers per request, read or write, is 4 registers.
The device will operate with the following default parameters:
Address: 247 (F7H)
Baud Rate: 57600 Baud
Transmit Delay Time: 20 msec
Some situations will cause the device to operate with the above Default Parameters. See
Section 9.4 for details of Default Mode.
9.7.3 Normal Mode
Normal Mode consists of one process: the device accepts new commands to control the
relays.
