YUAA Universal I/O Modules
The Mark VIeS Functional Safety System is used in a wide range of process control and turbo-machinery applications. The
IS430SSUAH1A Universal Analog Input/Output (I/O) module is enhanced I/O device designed for distributed control
systems (DCS) and balance of plant (BoP) control systems (where there are typically up to tens of thousands of I/O points,
requiring high availability). The module offers a reduction of cost per I/O point as compared to traditional analog I/O modules
(while maintaining high availability). A three-wire channel is located on a single terminal block section that fits onto a row of
the header. Each block section can be independently wired and then inserted, allowing channel by channel commissioning.
This enables much faster and more reliable terminations and decreases time to commission / maintain the system.

The YUAA module consists of the YUAAS1A I/O pack connected to the SUAAS1A
terminal board. The initial release of the module meets a variety of international
regulations and standards, including RoHs components.
Sixteen Simplex analog channels can be configured individually as any of the following
types: Thermocouple, RTD, Voltage Input (± 5 V or ± 10 V), 4–20 mA current input, 0–
20 mA current output, pulse accumulator, or digital input. Configuration of I/O
channels is accomplished with the ToolboxST* application.
The boards internal to the I/O pack include one BPPC processor, one BCAR carrier
board, and four MIO- universal analog I/O boards. The BPPC processor is common to
many Mark VIeS I/O packs. The SUAA terminal board provides removable terminal
blocks to reduce maintenance down times. The YUAA module operates on simplex
control side power as supplied by a 28 V source. There are no internal jumpers,
switches, or fuses required to configure the module.
The YUAA continues to meet the same high level of reliability/availability standards as
other Mark control system products. Savings to the customer include fewer
panels/footprint and variations for replacement parts.
The operating voltage limits on the user terminals are -12 to 20 V with respect to power
COM for analog modes. The digital input mode has an operating limit of 0 to 20 V for inputs
with no series resistance and up to 30 V for inputs with line monitoring resistors added.
Operation outside of these limits may impact operation of adjacent channels.
