Installation and commissioning
Option modules are monitored and controlled by the meter's ION modules. External I/O modules
are mapped to the corresponding ION modules:
Option module physical position
Module A to Module D
Option module terminal connector label
Analog inputs A1 to A(n)
Analog outputs Q1 to Q(n)
Digital inputs S1 to S(n)
Digital/relay outputs R1 to R(n)

Maximum number of option modules

Up to four option modules are supported per device.
Limitations:
• Only one Fiber Ethernet module may be installed.
• Depending on the type and quantity of option modules attached to your meter, you may need
to reduce your meter's maximum operating temperature or limit the number of option
modules. See
