Introduction
The 3159, 32-Channel Digital Output Card provides the user with the means to switch up to 32
points of DC voltage under program control. It can support a range of source voltages from
10 VDC to 30 VDC.
Output switching is performed by optically isolated power MOSFET drivers. The 32 output
channels are factory configured as sourcing outputs. When connected to field devices such as
an indicator lamp, solenoid valve, interposing relay, and other discrete control devices, the 32-
Channel Digital Output card can source up to 0.5 amps per channel, 8 amps maximum per card.
Active circuit testing provides line open and line short checking, on and off testing of FETs for
stuck conditions and channel readback values. Any fault detected is reported in the integer status
word for the card.
The card has one safety switch for every eight channels and is rated for SIL-3 applications. The
safety switch provides a secondary means of de-energizing the output channels in response to a
fault condition or watchdog timer timeout. Diagnostics test each output channel’s safety switch to
verify operation and reports any faults detected.
.
Watchdog timers on the card can open all of the output channels in the event backplane
communication errors persist.
An LED, located near the top of the front panel of the card, indicates the status of the card. If this
LED is on, the card is online; if it is off, the card is offline.

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 3159 digital output modules in a 2oo2 or
3oo3 configuration.

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).
Standard length for 3055/00 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. It must be also disabled (offline), if making online
changes and removing it from a redundant configuration. 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.
All terminal blocks are 2-tier and across the bottom of the termination. Pins 1 - 32 are the top
row. Pins 33 - 64 are the bottom row.

3299-11S Termination Module terminal block connections are the same pin designations as for the 3159 - 32
Channel Digital Output Card J2 Connector. For example, the signal for the field device connected to Channel 23
of the card would be connected to Pin 3 of the 3299-11S termination module.
