Using the I/O Option Cards
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.

Continuous load current: 120mA
Peak load current: 350mA for 10ms
On resistance, max.: 35Ω
Leakage current: 1µA@350V
Switching Rate max.: 10/s
Isolation: AC 3750V system to contacts
Reset/Power down state: Open contacts
Inputs
Number of inputs: 4
Sensing type: Wet or dry contact status detection
Wetting voltage: DC (12-24V), internally generated

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
