Using the I/O Option Cards
The 1mA card transmits a standardized bi-directional 0-1mA signal. This signal is linearly proportional to real-time
quantities measured by the meter. The outputs are electrically isolated from the main unit.
Ω load are as follows:
Number of outputs: 4 single ended
Power consumption: 1.2W internal
Signal output range: (-1.2 to +1.2)mA
Max. load impedance: 10kΩ
Hardware resolution: 12 bits
Effective resolution: 14 bits with 2.5kHz PWM
Update rate per channel: 100ms
Output accuracy: ± 0.1 % of output range (2.4mA)
Load regulation ± 0.06 % of output range (2.4mA) load step of 5kΩ @ ± 1mA
Temperature coefcient ± 30nA/°C
Isolation: AC 2500V system to outputs
Reset/Default output value: 0mA
Operating temperature: (-20 to +70) °C
Storage temperature: (-40 to +80) °C
Relative air humidity: Maximum 95%, non-condensing
EMC - Immunity Interference: EN61000-4-2
Weight: 1.6oz
Dimensions (inch) W x H x L: 0.72 x 2.68 x 3.26
External connection: AWG 12-26/(0.29 - 3.31) mm

5 pin, 0.200” pluggable terminal block
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:
Channel 1 +Watts, +1800 Watts => +1mA
-Watts, - 1800 Watts => -1mA
Channel 2 +VARs, +1800 VARs => +1mA
- VARs, -1800 VARs => -1mA
Channel 3 Phase A Voltage WYE, 300 Volts => +1mA
Phase A Voltage Delta, 600 Volts => +1mA
Channel 4 Phase A Current, 10 Amps => +1mA
