The ST-MIX combination I/O modules are part of the
SixTRAK I/O product line. Up to 20 of these modules
(any mix) can be connected to the high-speed I/O bus
of SIXNET controllers, RTUs and I/O gateways.
(Note: The ST-MIX is supported only by IPm-based
SIXNET Controllers, RTUs, and I/O Gateways.
Consult SIXNET for details. )
Specifications are subject to change. Consult the factory for latest information.

Advanced I/O Features and Capabilities
Discrete I/O Features
There are several groups of discrete I/O in these combination I/O modules that offer different capabilities to
accommodate a variety of system needs. Refer to the notes below and the wiring diagrams (next page) for further details.
 Sinking or Sourcing Discrete Inputs (First four on ST-MIX12884 or all sixteen on the ST-MIX16880)
This group of inputs may be configured as sourcing inputs (ON when positive voltage is applied) or sinking inputs
(switch closures to ground). There is a selection jumper in the module’s base that is easily accessed by unplugging the
logic module and opening the hinged door. You must also make a similar selection in the Discrete Options window in
the I/O tool Kit software. The module performs a check to verify that the hardware and software selections match.
 Adjustable Threshold Voltage (First four discrete inputs on ST-MIX12884 only)
This group of inputs may be modified to transition at a threshold voltage lower than the factory setting. This is
accomplished by simply soldering an extra resistor into the base. Refer to the user manual for details.
 Sourcing Discrete Inputs (Second group of eight discrete inputs on the ST-MIX12884 only)
This group of eight discrete inputs on the ST-MIX12884 is sourcing only with the standard 10 – 30 volt range.
 Sourcing Discrete Outputs and Watchdog Output (both models)
The eight outputs are sourcing (positive voltage applied when ON) with the standard 10-30V range. The first discrete
output can be configured to be a watchdog output. This system performance monitor will be ON if the output module is
functioning normally, the gateway is functioning normally or the ST-Bus communications are occurring normally
 High Speed and Special Counter Inputs (both models)
The first eight discrete inputs can be configured as counters with a flexible choice of modes. These counters report their
values in corresponding 16-bit analog input registers. Options for fast (5 mS) or slow (25 mS for contact bounce
filtering) response providing a maximum count rate of 100 Hz or 20 Hz counting, respectively. The 1st channel is a high
speed counter and can count up to 20 KHz. Available counter modes are pulse, rate and run-time.
Analog I/O Features
 Self-resetting Analog Input Protection
Each 4-20 mA input channel has a 100 ohm, high precision (0.1 percent) shunt across its input to develop a 2 volt signal
when a full scale 20 mA input is applied. These shunts are located in the module’s base, giving you the advantage of
maintaining a continuous circuit even if the logic module is removed from the base. If excessive voltage is applied to an
input, a self-resetting fuse will open to help prevent the shunt from overheating.
 Open Loop Detection on Analog Inputs
This module can detect and report an open instrumentation loop on its analog inputs. By allowing the module to report a
negative value if the current falls below 4 mA, low limit logic in your DCS, PLC, RTU or computer can signal the loss
of current. To enable this feature, select the “Go Negative Below 4 mA” software setting for each channel.
 Reading Voltage Analog Inputs
As an option, a voltage divider may be factory populated to replace the 20 mA (100 ohm) shunt of one or more input
channels. These alterations are made in the wiring base, so they may be tailored for particular installations. (The logic
modules are not altered so they remain interchangeable!) Voltage operation may be configured in the I/O Tool Kit by
selecting the appropriate range for the corresponding input. Consult SIXNET for ordering instructions.
 LED Indicators for Analog Inputs and Outputs
There is a LED for each of the analog input and analog output channels. The LED will be ON when the channel is within
the normal operating range of 4-20 mA. The LED will be OFF when an open loop is detected.
