Introduction
The 3108 and 3118 8-Channel High-Level Analog Input Cards provide high accuracy analog
measurements. Sampling transformers provide channel-to-RTP System and channel-to-channel
isolation. Very high noise immunity is characteristic of the transformer multiplexer, achieving in
excess of -140 dB of common mode rejection. Immunity to noise is further enhanced with a
double-pole low pass filter.
Analog to digital conversion is performed by a 16-bit switched capacitor successive
approximation A/D converter. Two precision voltage sources provide self-test function for the
card’s amplifiers and A/D converter and can be used to verify accuracy in user application logic.
The card also includes an onboard temperature sensor, which automatically compensates the
analog measurement for higher accuracy. This analog input card also has an internal 12-bit
DAC, which ramps periodically and verifies the operation of the ADC. No field adjustments are
necessary after the initial factory setup.
I/O bus checking diagnostics, card address tests, and configuration tests are performed each
time the controller accesses the card. All data and control transfers are performed twice, once
using the actual data and then using the inverted data. Both versions of the data are compared
to verify that all I/O bus data bits are functioning properly. The configuration code from the card is
compared to the I/O configuration to check that the correct card is installed in the rack. I/O Bus
slot address and control signal contention tests also are performed. Any fault detected sets
status bits in an error detection variable returned to the user application program.
An indicator LED, located near the top of the front panel, indicates the overall health status of the
card. If this LED is on, the card is functioning normally; if it is off, the card is offline. If this LED is

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 distribute +24 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 distribute +80 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.

Effect of Incorrect Field Wiring: Shorted connections produce zero analog input reading.
Open connections produce incorrect analog input reading in
voltage mode. In current mode, shorted connections will
produce zero analog input, which can be annunciated as
out-of-range in 4-20 mA configurations. Reverse
connections produce (sign) inverted analog input readings in
voltage mode. In current mode, reverse connections will
produce negative analog input reading, which can be
annunciated as out-of-range in the error status word.

Failure Rates in Accordance to IEC 61508
The following table summarizes the failure rates of the modules, which were calculated from
Failure Mode and Diagnostic Effects in accordance to standard IEC 61508. The information can
be used in calculating probability of dangerous failures using Reliability Block Modeling or Markov
Modeling. Such modeling should consider redundant 3108 analog input modules in a 1oo2, 2oo3
or 3oo4 configuration. Rates only applicable for 3108 only. 3118 is not safety-rated.

In dual redundant configurations, the users must exchange the card within Mean Time to Restore
(MTTR ≤ 9 days) in order to remain within SIL 3 requirements. Otherwise the card will continue
to operate in degraded SIL 2 mode.

Cabling
Adhere to the specified insulation strip length of 0.26 inches (6.5 mm) when you connect field
wiring to the terminal modules; excessive insulation strip lengths causes an electrical hazard. Do
not exceed the specified torque when you secure the wires into the terminal module; maximum
torque is 2.2 inch-pounds (0.25 N-m).
When not using an RTP termination module, input signals may be connected to the 8 channel
analog input card with user fabricated cable or RTP manufactured 3057/FL Flying Lead Analog
cable. 3057/FL cables have a diameter of 0.5 inches (1.27 centimeters) with a minimum bend
radius of 4.6 inches (11.69 centimeters).
Standard length for 3057/00 and 3057/FL cable is 5 feet.
You must disable (offline) an I/O card before you can hot-swap it. After you replace an I/O card,
you must enable it to return it to operation. While NetArrays is operating in Debug mode, use the
I/O Configuration Form to disable or enable I/O cards. To hot swap an I/O card, first display the
card’s icon in the I/O Configuration Form. If the I/O card’s icon is red, you can remove it. If the
I/O card’s icon is yellow or green, select the icon and disable it before you remove the card. After
you replace the I/O card, select the card’s icon and re-enable it. The color of the icon changes to
yellow or green to indicate the card is online.
WARNING! Dangerous high voltages may be present at the cards’ terminal blocks
during normal operation. When you service these cards, avoid contact with exposed
voltages on the card while you connect the field cabling. The field cabling terminal block
connectors also may have high voltages when disconnected from the card.
Warning! Never remove the card from the chassis with the termination cables
connected and the field power applied. Always disconnect the field power and cables
before removing the card from the chassis. Always insert the card into the chassis with
the cables and field power disconnected.
