1 INTRODUCTION
The CIO-RELAY16 is a 16 channel relay interface board for ISA bus computers. The
board provides 16 Form C (SPDT) relays. The CIO-RELAY08 board is designed for
applications that require fewer relays and is identical to the RELAY16 board except
that only 8 relays are installed. The CIO-RELAY32 is two CIO-RELAY16s on a single board while the CIO-RELAY24 is are CIO-RELAY32 with eight of the relays not
installed.
The /M versions (e.g. CIO-RELAY16/M and CIO-RELAY08/M) are identical to the
standard versions, but use Mercury wetted relays and offer quicker switch times, less
contact bounce and lower on-resistance than the standard models.
The CIO-RELAY16 family has been designed for control applications where a few
points of high voltage (or current) need to be controlled.
WARNING!
High voltages will be present on the CIO-RELAY16 family boards
when high voltage is connected to the CIO-RELAY16 connector.
Use extreme caution! Never handle the CIO-RELAY16 when signals are connected to the board through the connector.
DO NOT REMOVE THE PROTECTIVE PLATES FROM THE
CIO-RELAY16!
1.1 ACCESSORIES
The CIO-RELAY16 family are digital I/O boards with relay based signal conditioning
installed. Most accessory boards are intended to provide signal conditioning or easy
to access signal termination. In general, the CIO-RELAY16 will not require additional signal conditioning.
We recommend that under no circumstance should a screw terminal board be used to
connect high voltage s to the CIO-RELAY16 series boar d. The CIO-RELAY16 is
intended to control high voltages. If you use a screw terminal board you will expose
yourself and others to those high voltage signals.
We recommend that you construct a safe cable to carry your signals directly from your
equipment to the CIO-RELAY16 connector.

2 QUICK START
The installation and operation of all four CIO-RELAY series boards is very similar.
Throughout this manual we use CIO-RELAY as a generic d esignation for the CIORELAY08, CIO-RELAY16, CIO-RELAY24 and CIO-RELAY32. When required due
to the differences in the boards, the specific board name is used.
The CIO-RELAY boards are easy to use. This quick start procedure will help you
quickly and easily setup, install and test your board. We assume you already know
how to open the PC and install expansion boards. If you are unfamiliar or uncomfortable with board installation, please refer to your computer’s documentation.
We recommend you perform the software installation described in
the following sections prior to installing the board in your computer.
The
InstaCal
TM
operations below will show you how to properly set the switches and jumpers on the board prior to physically
installing the board in your computer.
2.1 Install the
Insta
CalTM software
Windows 95, 98 and NT users instal l InstaCAL by running the SET UP.E XE pro gram
included on your InstaCAL floppies or CD.
Windows 3.x and DOS user s install the pr ogram by running the INST ALL.EXE pro gram supplied on your InstaCAL disk.
These installation routines will create all required folders/directories and unpack the
various pieces of compressed software. Simply run install and follow the on-screen
instructions. Remember where the installed files are placed, as you will need to access
them in the next step (the default location is on your main hard drive in a directory or
folder named C:\CB\).

The form C relay has a COMMON, normally open (NO) and normally closed (NC)
contact. When a 0 is written to the output, the common and NC are in contact. When a
1 is written to the output the common and NO are in contact.
5.3 FORM A RELAYS (/M versions)
Shown here is the schematic for a form A relay as used on mercury wetted (/M)
models.
The form A relay has COMMON and normally open (NO) connections. When a 0 is
written to the output, the common and NO are disconnected. When a 1 is written to
the output the common and NO are in contact.

3 HARDWARE INSTALLATION
3.1 Mercury whetted (/M) board special considerations
The Mercury whetted boards must be mounted in the computer such that they will
remain within 30 degrees of vertical. Note that installation of these boards in most
tower computer cases will require the tower be rested on its side for proper operation.
3.2 BASE ADDRESS
The base address switch controls the I/O location where the CPU can access the registers of the CIO-RELAY board.
The factory default is 300H (768D).
If you have a board installed at address 300H, you will have to choose a new address
from those available on your computer. You may use the list of PC I/O address
assignments found on the fol lowing page and add notes a bout the boards you have
installed in your computer.
Choose a new base address from those available and set the switch using the guide
below.
Please note that the switch shown below is for the CIO-RELAY08 and CIORELAY16 boards. Since the CIO-RELAY32 and CIO-RELAY24 board require 4 I/O
address, their base address switch does not provide switch 2. All other settings are
identical.
If address 300H is available on your computer, we recommend that you select it. for
your board. The software examples are written for base = 300H.

3.3 WAIT STATE
There is a wait state jumper on CIO-RELAY series boards. The factory default is
wait state disabled. You will probably never need the wait state because PC expansion slot busses are limited to 8 or 10 MHz.
If you were to get intermittent operation from your CIO-RELAY board, you may try
enabling the wait state to see if that solves the problem.

CIO-RELAY24 and CIO-RELAY32 Connector
This connector is the center of the board. The connector for relays 0 through 15
is the connector that is closest to the computer back-plate. PINS corresponding
to relays 24 through 31 are not connected on the RELAY24 version.
The form A relays used on the /M versions
have NO and COM connections only!
WARNING!
High voltages will be present on the CIO-RELAY boards when you
have connected high voltage inputs or outputs to the CIO-RELAY
connector. Use extreme caution! Never handle the CIO-RELAY
when signals are connected to the board.! DO NOT REMOVE
THE PROTECTIVE PLATES FROM THE CIO-RELAY.

4 PROGRAMMING
The CIO-RELAY boards are easy to program. Eight bit registers located at the base
address and the base address plus an offset are written to control relays or can be read
to determine the state of relays.
In addition to direct I/O programming, the boards are fully supported by the powerful
Universal Library program as well as most third party application programs.
4.1 DIRECT I/O REGISTER PROGRAMMING
The CIO-RELAY family uses between one and four I/O addresses. Each address controls 8 relays and the relays are controlled by writing to these registers. The base
address maps of the CIO-RELAY boards are shown below.
BASE ADDRESS Relay 0-7 Read/Write
BASE + 1 Relay 8-15 Read/Write (RELAY16, 24, 32)
BASE + 2 Relay 16-23 Read/Write (RELAY24, 32)
BASE + 3 Relay 24-31 Read/Write (RELAY32 only)
The registers are written to and read from as a single 8 bit byte. Each bit controls an
output (write) or represents the state of a relay (read).
All registers are read left to right. The leftmost bit being the most significant bit. Following this format bit 7 of BASE+0 corresponds to relay 7 and bit 0 to relay 0.
To construct a control word, use the following table:

For example, to assemble the control byte that will turn on relays 0. 1. 3. 5 and 7 we
can see from the chart below we need to write decimal 171 (hex AB):

4.2 PROGRAMMING NOTES
WRITE = CONTROL: Write a byte to the register to control the relays. A one in the
relay bit position turns the relay on.
READ = STATUS: Read the status of the relay control register. A one in the relay
bit position indicates the relay is on.
ON & OFF for FORM C RELAYS:
On means that FORM C relay common is in contact with the Normally Open contact.
Off means that FORM C relay common is in contact with the normally closed contact.
