Warning!

The first index (PCB layout 00) of VMOD-2 was designed for
improved noise immunity (via multi-layer shielding) and as such
have insufficient clearance around the piggybacks I/O pins and the
50-way external interface connectors pins to ensure the 2.5kV
breakdown isolation specified by certain piggybacks. Use index 01
or higher for such applications, or take additional measures to be
taken to ensure syste m/user safety.

Product Overview

1. Introduction

1.1 Product Overview

VMOD-2 is a "User Configurable" Industrial I/O module with the ability to fit any two (identical
or different) standard sized VMOD piggybacks. Each fitted piggyback shares half of the front
panel's 50-way connector allowing a flat-ribbon cable to be easily routed to either one or two
end devices. The VMOD-2 may not only be used with all existing (VMOD) piggybacks, but will
also accept the future generation of enhanced piggybacks, which may use the additional sig­nal lines only provided on the VMOD-2.

Upgrade paths/Compatibility. The original VMOD is no longer available and if ordered will
automatically be replaced with the new VMOD-2. The VMOD-2 can be used as a direct
replacement for any application using an older style VMOD. Full electro-mechanical compati­bility (and acceptance of the existing piggyback int erfaces) is guaranteed.

The VMOD-2 may be used as a direct replacement for an y existing VMOD and will accept the
fitted piggybacks from that existing VMOD without any modification. (See also special note
below)

A VMOD may be used in place of the new VMOD-2 with the loss of some new features, and
then only with piggybacks developed up to the end of 1990. Any enhanced piggybacks which
need additional signals from the VMOD-2 will not work on the old VMOD. To identify which
piggybacks are only suit able f or use on the VMOD-2 loo k for a f our digit o rder number suc h as
the PB-BIT has. i.e. 5230-11. Any and all piggybacks with three digit numbers 523-xx, will
function with both VMOD and VMOD-2 modules alike.

Special Note! Caution!

VMOD-2 boards with an index 00 offe r increased inter-board shielding by
using tight-routed ground and V cc planes in their multi-layer layout. This
will compromise the 2.5 kV breakdow n isolation offered by many VMOD­piggybacks. If the 2.5 kV fault isolation is important for the application,

please use a VMOD-2 with a board index of 01 upwards since this will
have an increased galvanic isolation gap around the 50-way external
interface and 26-way piggyback I/O pin areas.

1.4 Hazards

The VMOD-2 can be fitted with one or two piggybacks carrying voltages classed as danger­ous (i.e. over 50V dc). These are usually powered by external devices and therefore are not
powered subject to the status of the VMEbus systems power switch. This can result in a
VMOD/VMOD-2 being removed from a powered-down rack with an external device still con­nected and presenting its voltage to the solder-side of both the VMOD/VMOD-2 and the back
of the respective piggyback. A typical example is the PB-REL an eight relay SPST switching
module, which can in certain circumstances present an unsuspecting user with up to 175V dc
when pulling out (or installing) a VMOD-2 with the external powered interface leads con­nected. (For continued fault isolation to 2. 5 kV use a VMOD-2 of index 01 or higher).

The VMOD-2 is a simple low-cost product designed for maximum flexibility while keeping the
single-height, single-slot modular concept of the PepCard. To ensure user/system security
against fault conditions is maintained with and when using opto-isolated piggybacks, the
VMOD-2 has a large area of unpopulated board space under the front half of both piggyback
locations. This unused area is part of the VMOD-2's Galvanic isolation (see special note on
page 1-1) and no additional wiring should be routed to/from component s in the rear-most area
of the VMOD-2 and the component groups (connectors) at the front of the VMOD-2. A "local­Reset" logic line is however routed to the three-p in j umper near the 50- pin fr ont pane l conne c­tor, but this follows distancing and opto-isolation rules to ensure that the galvanic capability of
the opto-isolated piggybacks is not compromised.

The VMOD-2 is shown above with both the 50-way front panel connector and the 50-way on­board header. It can only be ordered with one or the other. Further the VMOD-2 is shown with
the two piggyback locations occupied, which is how the majority of users employ their
VMOD's, but is delivered without any piggybacks, these items being added to the above illus­tration to help see where the connectors and piggybacks are to be found /used.

Each of the two piggybacks are fitted so their 26-way connector pins fit into the correspondi ng
26-way socket-holes provided for each piggyback location. The rear connectors pins will then
fit into the correct rows of the 30/45-way sockets regardless of whether the piggyback has a
30-pin or 15-pin connector.

All the jumpers, with the exception of B20 (local reset), are to be found at the back end of the
VMOD-2 in several small groups. Jumper B01 is an "L" shaped group of three-pins nearest
the top edge of the board, and the rest are consecutively numbered progressing down the
VMOD-2 until the last (Jumper B19) is reached nearest the bottom of the board. The function

12/15/97

VMOD-2/VMOD-2D

of these jumpers, and a detailed illustration of their locations and pin-numbering, are to be
found in chapter 3 of this manual.

The remaining components on this simple low-cost industrial base board are in CMOS SMD
logic and GALs to ensure reduced power consumption/thermal generation over it's predeces­sor.

Product Overview

1.7 Advantages and Features of the VMOD-2 PepCard

The VMOD-2 is an improved version of the original VMOD, which was designed with a major
objective in mind: to provide a low cost and easy to implement user configurable I/O interface
for industrial interface applications and/or space-savings in many different customer applica­tions.

This result is a maximized choice of design flexibility. The VMOD-2 provides a very cost­effective solution, with quick and easy implementat ion, and fu ll compatibil ity with the ex tensive
range of existing VMOD-piggybacks and the ability to accept the planed "enhanced" piggy­backs of the second generation.

With the flexibility offered by the VMOD-2 and the exi sting range of indust rial I/O modules, you
are able to configure many complex and usually very intense interfaces, in a very quick and
compact way. This may be especially important when needing to add interfaces to an already
existing system, or where when using other products several additional slots or a larger rack/
sub-frames or additional power supplies/cooling, were needed/used with their financial over­head.

Now with the VMOD-2 you may replace several of these existing cards, or external interface
boxes, with a single VMOD-2, fitted with two piggybacks containing the desired interfaces,
and also offering the added feature of a local res et input.

1.7.1Features of the VMOD-2 Module

Features of the VMOD-2 are:

* Widest possible range of base address selection to allow up to thirty-two VMOD-2's to

be used in any one system. (Prev iou sly onl y eight origi nal VMOD's coul d be fi tt ed due to

their fixed base addresses).
* Each piggyback location now supports 11 address lines. (A1...A11 to each piggyback).
* Each piggyback location now has 8/16-bit Databus lines. (D0..D15 to each piggyback).
* Galvanic Isolation between each interface and to the VMOD-2's VMEbus circuitry

depending upon the piggybacks fitted.
* External Reset facility, can be used to cause "local-reset" of the VMOD-2's piggybacks.
* Two Individually configurable piggyback locations, with board ID byte for remote (soft-

ware) configuration identity checking.
* Compact size, VMOD-2 plus two piggybacks containing your chosen interface circuitry,

are all contained within standard single-height, single-slot PepCard dimensions. Choice

of interface connector options, so where needed the connection method can be kept

internal, i.e. via a 50-pin on-board connector.
* Easy maintenance (i.e. swap-and-test, reduce service down-time)

VMOD-2/VMOD-2D

Hardware Features:

* Full electro/mechanical compatibility with the existing VMOD piggybacks and with the

very latest VMOD-2 enhanced piggybacks.
* All necessary VMEbus lines are made available to each of the piggybacks.
* 2.5 kV Galvanic VME to external isolation (not on index 00 boards), and PB to PB inter-

faces supporting opto-isolated piggybacks and the opto-isolated external "local" reset

input circuits.
* Extended temperature ver sions of bot h the VMOD-2 and many of the currentl y availab le

piggybacks, allowing combinations suitable for harsh industrial environments to be con-

figured.

1.10Piggyback Selection Assistance

As there are so many different types of piggyback available for the VMOD-2, and many offer
different options such as common ground or Vcc for their inputs, etc. the following selection
help chart has been provided. It may be used in conjunction with the piggyback overview table
on the next page. The prototyping piggyback is not shown in this figure.

All grey edged "coins" are decisions or group titles, all black edged coins are actual product
names and order numbers.
