Safety Precautions

This module (CD332) is a change detect DC input module for Toshiba’s Programmable Controller

PROSEC-T3 or T3H (hereafter called T3 generically). Read this manual thoroughly before using

this module. Also, keep this manual and related manuals so that you can read them anytime while

this module is in operation.

Safety Symbols

The following safety symbols are used on the product and/or in the related manuals.

Pay attention to information preceded by the following symbols for safety.

Indicates a potentially hazardous situation which, if not avoided,

could result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,

may result in minor or moderate injury. It may also be used to alert

against unsafe practices.

Safety Precautions

•Turn off power to the T3 and to the CD332 before removing or mounting the CD332.

Failure to do so can cause electrical shock or damage to this product.

•Read the Safety Precautions described in the T3 User’s Manual before using the T3

and the CD332.

•Follow the instructions described in this manual and in the T3 User’s Manual when

installing and wiring the T3 and the CD332.

•The CD332 has been designed for the T3. Use your CD332 only on the rack of the T3.

•Remove the CD332 from the rack before setting the jumper plugs on the CD332.

Do not touch other components on the CD332’s printed circuit board. It may cause

damage to the CD332.

•The CD332 consumes maximum 0.3 A of internal 5 Vdc power. Confirm that the total

5 Vdc consumed current per one power supply module is within the limit (7A).

If it exceeds the limit, the T3 cannot operate properly and this may cause unsafe

situation.

6Change Detect DC Input Module (CD332)

1. CD332 Overview

1.1 Introduction

The change detect DC input module CD332 (hereafter called CD332) is an 8 points 12

- 24 Vdc input module with interrupt generation function for Toshiba’s Programmable

Controller PROSEC-T3 or T3H (hereafter called T3 generically).

When the input signal status of the CD332 is changed, the CD332 generates an

interrupt for the T3. Then the T3 immediately stops ordinary operation and starts to

execute the pre-assigned I/O interrupt program.

The task switching time in the T3 is less than 500 µs. (under interrupt enable state)

The interrupt generation timing of the CD332 can be selected as follows for each input

point. This selection is made by the DIP switches provided on the front of the CD332.

(1) Rising edge (from OFF to ON)

(2) Falling edge (from ON to OFF)

(3) Both edges (both OFF to ON and ON to OFF)

This CD332 has 8 input points. By using one CD332, up to 8 interrupt factors can be

processed. On the other hand, up to 8 I/O interrupt programs are available in the T3.

Therefore, total up to 64 (= 8 ×8) interrupt factors can be processed by the T3 by using

8 CD332s.

The input voltage of the CD332 is 12 to 24 Vdc. The input delay time can be selected

either normal or high speed as 8 points block by setting the internal jumper plugs.

NOTE

The T3 supports 8 I/O interrupt programs. Therefore, maximum 8 CD332s

can be used with the T3.
