Performance to Improve Productivity

The VersaMax Micro family is designed to provide the

power and performance of customized solutions with the

convenience and economy of off-the-shelf technology.

VersaMax Micro PLCs have two  channels of high-speed

control, two independent 65kHz pulse and direction outputs,

and user configurable inputs and outputs to effectively

increase machine performance. With VersaMax Micro PLCs

you  can reduce costs and save time on machine configurations

without compromising the ability to customize the features

that are right for your application.

Simplified Programming for PLCs

With PAC Machine Edition software, programming your

VersaMax Micro PLCs is an intuitive process. Mix Relay Ladder

Diagram and Instruction List programming within an

application. Develop and save custom view tables. View PLC

and I/O system fault tables on demand. PAC Machine Edition

deploys HMI, motion, and multi-target control in an integrated

development environment. This provides a common user

interface, drag-and-drop editing, and a rich set of development

tools. The Micro 20. Micro 40 and Micro 64 support a portable

program FLASH Memory Module that provides a simple cost

effective way of upgrading field controllers.

The Micro 64 PLC is big on features, expandable to 176 I/O points to fast cycle times, 

robust instruction set, and generous memory to allow more flexible programming.

The optional second port provides you with the option of an additional RS-232 port, RS-485. USB, or Ethernet.

The serial expansion ports come with two analog input channels.

A user-friendly memory module is available to easily download changes to the controller without the need of a PC.

And it’s all packaged in a sturdy modular design for easy access and long-term durability.

This all-in-one PLC gives you everything you need to control a wide variety of applications.

AC Power Source Connections

The Hot, Neutral, and Ground wires from the

20 VAC power source or L1, L2. and

Ground wires from the 240 VAC power source connect to the system through the top three

terminals of the terminal strip on the front of the power supply.

DC Power Source Connections

Connect the + and – wires from the

25 VDC (nominal) power source to the top two

terminals on the terminal connector.  These connections are not polarity-sensitive on an

AC/DC input power supply.  (However, the DC Input-only type supplies, which are

discussed later in this chapter, are polarity sensitive.)

Input Overvoltage Protection Devices

This information applies to all Series 90-30 power supplies except IC693PWR322

and IC693PWR328.  The overvoltage protection devices for this power supply are

connected internally to pin 4 on the user terminal strip.  This pin is normally connected to

frame ground (pin 3) with the supplied jumper strap which is installed at the factory.  If

overvoltage protection is not required or is supplied upstream, this feature can be disabled

by  removing the jumper strap from pins 3 and 4.

The IC693PWR330 High Capacity Power Supply is rated for 30 watts output.  For applications

requiring greater +5V current capacity than is available with the standard supply

(IC693PWR321), this supply allows all 30 watts to be consumed from the +5V supply.  It can

operate from an input voltage source in the range of 85 to 264 VAC or

100 to 300 VDC. This power  supply provides the following outputs:

• +5 VDC output.

• +24 VDC Relay power output which provides power to circuits on Series 90-30  Output Relay

modules.

• Isolated +24 VDC, which is used internally by some modules, can also be used to provide

external power for 24 VDC Input modules.

Field Wiring Connections for the AC/DC Input Power Supplies

The two AC/DC input power supplies have six terminals for user connections.  These connections

are described below.

Output Data Transfer:

Data for each analog output

channel is written directly into an on-board register

location dedicated to a specific channel.  The data is

then periodically retrieved from the register, and

converted to an analog voltage which is transferred to

one of 32 output sample-and-hold buffers.

A/D Data Format (Built-in-Test Data):

Analog

inputs are first digitized, then the 12-bit digital values

(D11 to D00) are read at a single memory word location.

In two’s complement mode, the upper four bits (D15.

D14. D13. and D12) are read as the sign extension of the

12-bit digital value, otherwise they are read as logical zeros.

Built-in-Testing:

Built-in-Test logic provides the user

with the capability to test all of the active components on

the board, including the output switches. This test

scheme utilizes an on-board analog-to-digital converter

(ADC) and multiplexers, as shown in Figure 1.

Memory Testing:

This product is designed with

dual-port on-board registers that may be tested by

executing a user-defined memory test program for

additional performance verification.

System Reset:

Application of the system reset signal

via the VMEbus initializes the board into a state with all

analog outputs disconnected from the output.

FUNCTIONAL CHARACTERISTICS

VMEbus Compliance:

The analog output board is a

standard double height printed circuit board which is

compatible with the VMEbus specification (Rev. C.1).

VMEbus A16:D16

Board Address:

The physical address for the board

may be selected by on-board jumpers.  VMEbus address

lines A07 through A15 are decoded for board selection.

VMEbus Access:

Address modifier bits are

jumper-selected and decoded to support both

nonprivileged short I/O, supervisory short I/O, or both.

The board is factory-configured for supervisory short I/O.

provides 32 discrete input points that operate at levels up to 30V.  Power to operate field

devices can come from an external supply or from the module’s isolated +24 VDC output.

48VDC 32 Point Positive/Negative Logic Input module, IC694MDL658. provides

32 discrete input points that operate at levels up to 60V.  Power to operate field

devices must be provided using an external supply.

The blue band on the front label indicates a low-voltage module.

These modules do not report special fault or alarm diagnostics.  Green LEDs

indicate the ON/OFF status of each input point.

These modules can be installed in any I/O slot in the RX3i system.

LOCATIONS ONLY

• WARNING – EXPLOSION HAZARD – SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR

PACSystems RX3i 32-Point Positive/Negative Logic input modules provide 32

positive or negative logic input points in four isolated groups of eight. Each group is

referenced to its own common connection.

5/12VDC (TTL) 32 Point Positive/Negative Logic Input module, IC694MDL654.

shown at left,  provides 32 discrete TTL voltage threshold input points that operate

at levels up to 15V.  A single, regulated +5V supply (current limited to approximately

150mA) is available through the I/O connectors on the front of the module.  This

supply is generated on the module and is isolated from the backplane.  Its power

input comes from the +5V logic supply on the PLC backplane.  By installing jumpers

on the I/O connector, you can choose to power the inputs from this internal supply

instead of powering them with an external user provided supply.
