CAE I/O Replacement

 

 

Overview

TMI has been providing I/O systems for the nuclear simulation industry for nearly 20 years. TMI offers many types of I/O systems as replacements for simulators. TMI has direct replacements for Singer (all versions)/EAI, CPI and RTP I/O systems, CAE and VMIC. TMI’s direct replacement I/O systems reduce the workload when upgrading as well as eliminates the need for cable adapters.

 

TMI has become the leader in the U.S.A. for I/O systems within the nuclear simulation market, in fact TMI delivers more I/O systems then all other vendors combined. TMI’s reputation has grown worldwide and as such, has been supplying I/O systems to Europe, Asia and Africa. TMI’s products are used predominately in the nuclear simulation industry and also have been used in fossil simulation. TMI’s focus is devoted to the simulation industry.

 

Hardware Description

The 765x I/O system is an Ethernet based distributed I/O system. It has an industry standard TCP/IP protocol. Each Ethernet Controller can handle over 3,000 I/O points. All the chassis are packaged in 6U VME size card cages. Each card cage can have 24 I/O cards (DO/DI/AO/AI). Any combination is acceptable. Connections on the DO/DI/AO/AI cards are through the P2 connector. The P2 is a 72 pin board edge connector.

 

Ethernet Controller Chassis

At the heart of the I/O system is the 7656-1 Ethernet Controller. This Ethernet based device connects directly to the simulator computer and is responsible for the direct communication and control of all the I/O cards within the chassis. The Ethernet Controller is located in the first slot of every card cage assembly.  A maintenance communication port is provided for running on line and off line diagnostics. The Ethernet Controller can directly drive up to 48 I/O cards (DO/DI/AO/AI).

 

Chassis Controller Chassis

The Chassis Controller Chassis (7657-1) is a satellite chassis of the Ethernet Controller Chassis. This Chassis connects directly to the Ethernet Chassis over a 40 pin bus know as the Chassis Bus. The Chassis Controller is located in the first slot of the card cage assembly. 

 

DO Card with Intelligent Drivers

The 7652-1 DO cards are 48 bits and use intelligent driver chips. The most common DO card uses sink drivers. These provide a ground (low level) to the I/O point, typically used to drive lamps and relays. The driver chips are socketed for ease of repair. These drivers sense over current and over temperature and reduce their output so they do not exceed the components parameters, in other words when they sense an out of tolerance condition they reduce their output current and protect themselves. They can directly drive LED’s without ghosting. TMI offers 3 options for the DO Board, these include high current/voltage sink drivers, and TTL level outputs as either high true or low true states. The high current drivers have a maximum working voltage of 60 volts and 1.0 amp. The TTL drivers are TTL levels at +/-24ma. All outputs are on the P2 connector. This is a 72 pin card edge connector.

 

DO Card with Source Drivers

The 7652-2 DO cards have 64 bits of output. The outputs provide a source voltage rather than a sink current. They are fully protected drivers which sense over current and over temperature conditions and shut down the output to protect themselves. All outputs are on the P2 connector. This is a 72 pin card edge connector.

 

DI Card with Protected Inputs

The 7653-1 DI cards are 64 bit DI’s and senses a low level to go to the true state. The inputs are internally pulled up to 15 volts and when driven below 5 volts the input is active. The inputs are protected to +/-36 volts. All inputs are on the P2 connector. This is a 72 pin card edge connector.

.

Analog Output Card (VOLTAGE)

The 7654-1 is a 32 channel voltage AO (analog output). The AO can be set for up to 4 output ranges, (0-5 volts, -5 to 5 volts, 0 to 10 volts and -10 to 10 volts). The AO’s use 16 bit DAC’s and source and sink +/-20ma. All outputs are on the P2 connector. This is a 72 pin card edge connector.

 

Analog Output Card (CURRENT)

The 7654-2 is a 32 channel current AO (analog output). The AO card supplies a current of 0-21ma per channel. The AO’s use 16 bit DAC’s. All outputs are on the P2 connector. This is a 72 pin card edge connector.

 

Analog Output Card (VOLTAGE)

The 7654-3 is a 8 channel voltage AO (analog output). The AO can be set for up to 4 output ranges, (0-5 volts, -5 to 5 volts, 0 to 10 volts and -10 to 10 volts). The AO’s use 16 bit DAC’s and source and sink +/-20ma. All outputs are on the P2 connector. This is a 72 pin card edge connector.

 

Analog input Card

The 7655-1 has 16 Analog Inputs. The AI is set for a 1 -5 volts range. Each input is protected up to 70 volts. The AI’s use 16 bit ADC’s. All inputs are on the P2 connector. This is a 72 pin card edge connector.

 

I/O Power Supply

The 7834-3 is a 600 watt AC/DC power supply chassis. The input voltage is 85 to 264VAC. The input contains an inline circuit breaker, line filter and on/off switch. The power supply is housed in a 3” x 7” x 19” rack mount enclosure..

 

Hardware Offline tests

TMI I/O systems provide the user with both online and offline tests. These tests allow the hardware personal to locate problems quickly. A DORT test is self contained in the Ethernet Controller. It does not require a PC to run. This is useful to verify the simulator as a whole or a section of panel. DORT tests consist of Lamp Step, AO Sweep, AO Set, AO Step, DI Test and Synchroscope Test. The online tests are “Preset and Monitor” tests. This allows the user to Preset an AO or DO or Monitor an AI or DI.

 

Hardware Requirement

The computer system used to drive the I/O must have an Ethernet (10/100 minimum) connection with TCP/IP. A 10/100/1000 switch is recommended.

 

Warranty

The system comes with a five (5) year warranty.

 

Installation

TMI can provide installation assistance if necessary. The installation includes mounting and cabling all the hardware supplied by TMI.

  

Maintenance

All TMI customers are self-maintainers. They need the documentation to perform their maintenance. All schematics, technical manuals are provided.
