Using the I/O Option Cards
20mA Output Card (-4)
The 20mA card transmits a standardized 0-20 mA signal. This signal is linearly proportional to real-time quantities
measured by the meter.
The current sources need to be loop powered.
The outputs are electrically isolated from
the main unit.
Specifications
the technical specifications at 25° C at 500
Ω
load are as follows:
Number of outputs:
4 single ended
Power consumption:
1W internal
Signal output range:
(0 to 24)mA
Max. load impedance:
850 Ω @ 24VDC
Hardware resolution:
12 bits
Effective resolution:
14 bits with 2.5kHz PWM
Update rate per channel:
100ms
Output accuracy:
± 0.1 % of output range (24mA)
Load regulation:
± 0.03 % of output range (24mA) load step of 200Ω @ 20mA
Temperature coefficient
± 300n A/°C
Isolation:
AC 2500V system to outputs
Maximum loop voltage:
28Vdc max
Internal voltage drop:
3.4VDC @ 24mA
Reset/Default output value:
12mA
the general specifications are as follows:
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/(0.129 - 3.31)mm
2
5 pin, 0.200” pluggable terminal block
default Configuration:
The meter automatically recognizes the installed option card during Power Up. If you have not programmed a
configuration for the card, the unit will default to the following outputs:
Channel 1
+Watts, +1800 Watts => 20mA
-Watts, -1800 Watts => 4mA
0 Watts => 12mA
Channel 2
+VARs, +1800 VARs => 20mA
- VARs, -1800 VARs => 4mA
0 VARs => 12mA
Channel 3
Phase A Voltage WYE, 300 Volts => 20mA
0 Volts => 4 mA
Phase A Voltage Delta, 600 Volts => 20mA
Channel 4
Phase A Current, 10 Amps => 20mA
0 Phase A Current, 0 Amps => 4 mA
