Features

1.     Allows use of PT100 or thermocouple DIN board with IP-MADC-8403.

2.     Allows use of four 8403 on all 8002 carrier board sites

3.     Four 50-way connectors

4.     Programmable current outputs from 8403s

5.     On-board DC-DC converters supply 8403s and DC excitation

6.     Twisted pair pseudo-differential inputs.

Specification

Mechanical:                       Standard 6U high VME64X transition board

Number of channels:           64
Input/output voltage range: 0 to +2.5V
Input filter:                       1K in each arm with 0.1uF across them.
Common mode resistors:     1M to Agnd from each arm
Three pole jumpers:            Select single inputs from signal to common or differences between adjacent inputs.
Excitation:                         Programmable 0-1mA  supplied by 8403
Isolated digital output:        /CALEN allows  external switch control by 8403
ADC Isolation:                    100V with respect to VME 0V limited by 8403
Power:                              +5V @ 4A typical if DC-DC converters fitted.

Operating Modes

 Configuration

There are two basic operating modes:-

1. Signal to common
2. Signal to signal.

Jumpers

Jumpers on each signal return connect them either to the 8403 common input or to the next signal input so that single-ended or differential measurements can be made.

 Excitation

Two current sources and +/-12V are available:-

1. +/-12V D.C.
2. Programmable current source 0 to +1mA

Connectors

 Four 50-way connectors routed to carrier board sites A,B,C and D provide 16 single-ended voltage inputs or 15 difference inputs.
