Using the I/O Option Cards
Pulse Output (Solid State Relay Contacts) / Digital Input Card (-2)
The Pulse Output/Digital Input card is a combination of pulse outputs via solid state contacts and dry/wet contact
sensing digital inputs. The outputs are electrically isolated from the inputs and from the main unit.

Default Conguration:
The meter automatically recognizes the installed option card during Power Up. If you have not programmed a con-
guration for the card, the unit will default to the following outputs:
Status Inputs Defaulted to Status Detect
Pulse Outputs Defaulted to Energy Pulses
Pulse Channel 1 1.8 +Watt-hrs per pulse
Pulse Channel 2 1.8 -Watt-hrs per pulse
Pulse Channel 3 1.8 +VAR-hrs per pulse
Pulse Channel 4 1.8 -VAR-hrs per pulse
