INTRODUCTION
1.1 GENERAL DESCRIPTION
ControlWaveLP Remote Terminal Units are comprised of a three board set (CPU Board,
Fixed Multifunction Input/Output Board & the Power Supply/Sequencer Board) that have
been designed and integrated to provide high performance with low power consumption.
The CPU Board employs the Ultra Low Power Intel 486SX microprocessor with core logic
support provided by an R400EX System Controller IC. The basic assembly includes 5
asynchronous PS/2 compatible communication ports. The Fixed Multifunction Input/Output
Board (FMI/OB) provides the circuitry and field interface hardware required to interface up
to 16 Discrete Inputs, 8 Discrete Outputs, 8 Analog Inputs and 4 High Speed Counter
Inputs. Additionally the FMI/OB provides LEDs for each DI, DO and HSC point as well as 6
CPU status LEDs, an LED for each of the five Comm. Ports and LEDs for Watch Dog, Idle,
Master Clear and Power Fail indications. Isolated power is generated and regulated by the
Power Supply/Sequencer Board (PSSB) that provides +5Vdc, +12Vdc and -12Vdc from a
bulk 9 - 30 Vdc source.
