The Analog Input Modules (0 ±1mA, 0 ±20mA, 0 ±5Vdc and 0 ±10Vdc) are available in 8-
channel format. Maximum registers per request, read or write, is 17 registers.
The EPM 9450/9650 meter supplies power for up to 4 connected Analog Input 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.
All inputs share a single common point. This is also an isolated connection (from ground).
The Modbus Map for the Analog Output Module (and operating details) can be found in the
Modbus Communicating I/O Modules Manual.
