Page 9: Section 1 - Introduction
SECTION 1 - INTRODUCTION OVERVIEW The Analog Output Module (IMAOM01) is a microprocessor based INFI 90 module that generates eight individual analog output signals used to control a process. It develops these sig- nals using data received from other INFI 90 devices. Algorithms performed in a master module determine the Analog Output Module (AOM) output signals. -

Page 16: Section 2 - Description And Operation
SECTION 2 - DESCRIPTION AND OPERATION INTRODUCTION This section explains the output circuitry, logic, data, logic power and connections for the Analog Output Module (AOM). The AOM generates analog output signals from values deter- mined by a Multi-Function Processor, Multi-Function Control- ler or Controller Module. -
Page 17: Control Logic
DESCRIPTION AND OPERATION ® Control Logic CPU Block The Central Processing Unit (CPU) consists of an eight bit microprocessor, 4K PROM, 1K RAM, data buffer, address decoders, programmable timer and digital clock. An eight bit bidirectional data bus and 16 bit address bus connect the dif- ferent components. -
Page 18: Isolation Circuit
DESCRIPTION AND OPERATION Frequency Divider Block A frequency divider network uses the 4 MHZ crystal oscillator on board the AOM to develop the various clock signals for mod- ule bus interface functions, and microprocessor and timer cir- cuit requirements. D/A Block The Digital to Analog (D/A) converter block consists of a volt- age reference circuit, 10 bit D/A converter and buffer amplifi- ers. -
Page 19: Analog Output Circuit
DESCRIPTION AND OPERATION ® sequences through the rest of the channels. Voltages from the S/H circuits drive the output circuits. The CPU cycles through each S/H circuit in sequence to refresh each corresponding output channel. It uses stored data to maintain the output levels or new data to change the outputs. -
Page 20: Output Circuit Connections
DESCRIPTION AND OPERATION OUTPUT CIRCUIT CONNECTIONS The output circuits connect to the 30-pin card edge connector P3. The outputs are routed to a TU/TM using a termination cable. P3 also supplies +24 VDC power from the TU/TM to the AOM. This voltage drives the analog output circuits. MODULE BUS The INFI 90 module bus is a peer-to-peer serial communication bus. -
Page 21: Read Point
DESCRIPTION AND OPERATION ® for only one output channel. The AOM converts a 24 bit per- centage value (REAL-2/3) to generate an analog output. The value in a write point message from a master module is dependent on FC 28 in the master module configuration. An output point (channel number) must be defined in a FC 28 block to output a control signal for that point. -
Page 22: Machine Fault Timer
DESCRIPTION AND OPERATION MACHINE FAULT TIMER A Machine Fault Timer (MFT) generated on board the AOM is a security feature common to all microprocessor based INFI 90 modules. The timer is reset periodically by the microprocessor. If it is not reset within a set time, the timer times out causing the module to shut down ( time out). -
Page 23: Section 3 - Installation
NOTE: Refer to Product Instruction I-E93-911 for termination device wiring instructions. SPECIAL HANDLING NOTE: Always use Bailey's Field Static Kit (P/N 1948385A2 - con- sists of wrist strap, ground cord assembly, alligator clip) when work- ing with modules. The kit is designed to connect a technician and the static dissipative work surface to the same ground point to pre- vent damage to the modules by electrostatic discharge. -
