INTRODUCTION
These external expansion modules add functionality to any
PRO
PLUS
in
the field. They can be added at any time and are easy-to-install.
Add a 4-relay expansion module and/or up to two I/O modules. The
menu items for these modules do not appear until the module is con-
nected, simplifying the basic menu.
The relay module consists of four 3 amp Form A (SPST) relays.
The I/O module has four digital inputs and four digital outputs per module.
External digital inputs can function similarly to the front panel function keys.
They can be configured to trigger certain events (i.e. acknowledge/reset
alarms, reset max and/or min values, disable/enable all output relays, and
hold current relay states), provide direct menu access point, or mimic front
panel keys. Digital outputs can be used to remotely monitor

relay output states, or the states of a variety of actions and functions ex-
ecuted by the meter.
RS-232 or RS-485 communications modules are also available; refer to
the accessories section for ordering details.
