Introduction
The 16-Channel Analog Output Cards provide high-precision analog output signals. This card
can be purchased factory-configured to generate 4 mA to 20 mA outputs for the current option; or
0V to +10V outputs or –10V to +10V outputs for the voltage option. All channels are isolated from
RTP chassis ground.
The 16-Channel Analog Output card’s model number determines the channel output options as
follows:
3236 Current Output Channels (4 to 20 mA)
3237 Voltage Output Channels (0 V to +10 V or –10 V to +10 V)
Each channel consists of a digital-to-analog converter. Individual D/A converters generate the
sixteen outputs. 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 data inverted. 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.
Watchdog timers on the card can open all of the output channels in the event backplane
communication errors persist.

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, indicates
an error in the cards calibration data.

Termination Module Connectors: 37 pin D-Sub connector for use with the 3056/00 Digital
Cables. These cables have a diameter of 0.5 inches (1.27
centimeters) with a minimum bend radius of 4.6 inches
(11.69 centimeters).
Termination Module: 3099/60-100 Single Termination Module 16 Channel AO
Voltage (used with 3237 card)

Current (used with 3236 card)
Effect of Incorrect Field Wiring: Outputs can be shorted to ground indefinitely. Connections
may be left open indefinitely. Reversed terminal connections
results in reversed polarity output applied to load.
Termination Module Dimensions: All Termination Modules are 4.38 inches (11.1 centimeters)
in height and have 3.75 inches (9.5 centimeters) of depth.
The width for each termination module and the compatible
field wiring size is tabulated as following:

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 can cause 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).
Standard cables to termination modules are minimum 5 feet in length.
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
green to indicate the card is online.
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.

Failure Rates in Accordance to IEC 61508
The 3236 and 3237 analog output cards cannot be used for safety-critical functions. However, the
module is non-interfering with other safety-critical modules and therefore can be used for non-
safety related functions.
