INSTRUCTION MANUALNPN TRANSISTOR OUTPUT MODULE, 16 points MODEL R8-DCT16A2(with short circuit protection, Tension clamp terminal block)
BEFORE USE ....
Thank you for choosing us. Before use, please check contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact our sales office or representatives.
■ PACKAGE INCLUDES:
NPN transistor output module............................................(1)■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.

■ AND ....
• The unit is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required forsatisfying complete performance described in the datasheet.

INSTALLATION■ HOW TO MOUNT THE MODULE ON DIN RAIL
• I/O ModuleA■ INSTRUCTION MANUALThis manual describes necessary points of caution when
you use this product, including installation, connection andbasic maintenance procedures.

POINTS OF CAUTION■ CONFORMITY WITH EU DIRECTIVES• The equipment must be mounted inside a panel.
• The actual installation environments such as panel configurations, connected devices and connected wires may
affect 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 CE conformity.

BConfirm that the locking clamps of the I/O module are set.
Insert the module in parallel to the next one while aligning the grooves ofboth modules (A & B in the above figure).
Maintain it perpendicularly to the rail.

■ GENERAL PRECAUTIONS• Before you remove or mount the unit, turn off the power
supply and output signal for safety.
• Switches on the side of the module can be set for maintenance only while the power supply is off. Do not accessthem while the power is supplied.
■ ENVIRONMENT• Indoor use.
• When heavy dust or metal particles are present in theair, install the unit inside proper housing with sufficientventilation.
• Do not install the unit where it is subjected to continuousvibration. 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% RHin order to ensure adequate life span and operation.

More I/O modules can be added in the same manner.

■ WIRING• Do not install cables close to noise sources (relay drivecable, 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.
■ EXCITATION SUPPLY• Output connector: Rated current 3 A DC (rated current 3A for internal fuse (slow blow fuse i2t (A2sec) max. 5.04).

R8-DCT16A2■ HOW TO UNMOUNT THE MODULE FROM DIN RAIL

• Protective Cover

Release the locking clamps and pull out straight the module.
HookGroove

The protective cover is to be attached over the connected I/O module
at the right end.
Align the hooks on the cover with the grooves of the module and slide itstraight until the hooks are latched.

• Removing an intermediate module

When removing the cover, pull it out while squeezing the hooks inward.

Caution !
1) Be careful not to hurt your hand by pointed edges of the internal
communication bus connector.
2) I/O modules cannot hold tightly on the DIN rail by themselves without
power/network module.
Secure them to the position if necessary by using DIN rail end plates.
