on, but the card is shown in red on the NetArrays IOC screen and cannot be enabled, this
indicates an error in the cards calibration data.
For long term accuracy, the calibration channels should be monitored to the desired accuracy
tolerance.
In order to measure current, the 3099/11 Termination Module contains eight (8) 0.01% precision
250
resistors that convert the input currents to voltages for measurement by the card. The
3099/11 termination module can also dist24 VDC fused power through a resettable fuse,
per channel, rated at 300 mA, 30 Volts max, to current mode sensors.
Another current measurement option, the S3099/11-001 Termination Module contains eight (8)
0.01% precision 100
resistors that convert the input currents to voltages for measurement by
the card. The S3099/11 Termination Module can also dist80 VDC fused power through a
replaceable fuse rated at 2.5 amps, 80 Volts max, to current mode sensors. Each channel on the
S3099/11-001 has a 125 mA replaceable fuse.
The 3108 and 3118 cards can be used with user supplied field termination. The card can be
connected to the field termination by using RTP supplied flying lead termination cable or user
supplied field wiring/cabling.
