1mA Output Card (IQ250/260-IO3)
The 1mA card transmits a standardized bi-directional 0-1mA signal. This signal is linearly proportional to real-time
quantities measured by the IQ 250/260 meter. The outputs are electrically isolated from the main unit.
Specifications:
The technical specifications at 25° C at 5k
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 coefficient
± 30nA/°C
Isolation:
AC 2500V system to outputs
Reset/Default output value:
0mA
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/(0.29 - 3.31) mm2
5 pin, 0.200” pluggable terminal block
Default Configuration:
The IQ 250/260 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 => +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
