contents of the package you received as outlined below.

If you have any problems or questions with the product,

please contact M-System’s Sales Ofﬁce or representatives.

■PACKAGE INCLUDES:

Discrete I/O module ............................................................(1)

■MODEL NO.

Conﬁrm Model No. marking on the product to be exactly

what you ordered.

■INSTRUCTION MANUAL

This manual describes necessary points of caution when

you use this product, including installation, connection and

basic maintenance procedures.

POINTS OF CAUTION

■CONFORMITY WITH EU DIRECTIVES

• The equipment must be mounted inside the instrument

panel of a metal enclosure.

• The actual installation environments such as panel con-

ﬁgurations, connected devices, connected wires, may af-

fect the protection level of this unit when it is integrated

in a panel system. The user may have to review the CE

requirements in regard to the whole system and employ

additional protective measures to ensure the CE conform-

ity.

• Install lightning surge protectors for those wires connect-

ed to remote locations.

■POWER INPUT RATING & OPERATIONAL RANGE

• Locate the power input rating marked on the product and

conﬁrm its operational range as indicated below:

24V DC rating: 24V ±10%, approx. 40mA

■GENERAL PRECAUTIONS

• Before you remove the unit or mount it, turn off the power

supply, input and output signal for safety.

• Before you remove the terminal block or mount it, turn

off the power supply, input and output signal for safety.

• DO NOT set the switches on the module while the power

is supplied. The switches are used only for maintenance

without the power.

■ENVIRONMENT

• Indoor use.

• When heavy dust or metal particles are present in the

air, install the unit inside proper housing with sufﬁcient

ventilation.

• Do not install the unit where it is subjected to continuous

vibration. Do not subject the unit to physical impact.

• Environmental temperature must be within -10 to +55°C

(14 to 131°F) with relative humidity within 30 to 90% RH

in order to ensure adequate life span and operation.

• Be sure to close the terminal cover for safety.

■WIRING

• Do not install cables close to noise sources (relay drive

cable, high frequency line, etc.).

• Do not bind these cables together with those in which

noises are present. Do not install them in the same duct.

■AND ....

• The unit is designed to function as soon as power is sup-

plied, however, a warm up for 10 minutes is required for

satisfying complete performance described in the data

EXAMPLE OF OPERATION MODES

■MAINTAINED OUTPUT MODE

Example of Y0 is shown below.

Bit 0 OFF

OFF

■MOMENTARY OUTPUT MODE

Y0 and Y1, Y2 and Y3, Y4 and Y5, Y6 and Y7 are respectively combined to realize momentary switching with one-shot output.

Bit 0, 2, 4, 6 are used to control each set of outputs, while Bit 1, 3, 5, 7 are unused.

An example of Bit 0 controlling Y0 and Y1 outputs sequentially is shown below.

1) Output data Bit 0 is turned from 0 to 1.

2) Following the rising edge of Bit 0, Y0 one-shot output turns ON for a ﬁxed period of time (SW1 time setting).

3) Bit 0 is turned from 1 to 0.

4) Following the sinking edge of Bit 0, Y1 one-shot output turns ON for a ﬁxed period of time (SW1 time setting).

Note: If Bit 0 receives multiple data during the one-shot output time period, the Y0 provides only the last output data received

within approx. 25 milliseconds after the period.
