Digital I/O Terminal 2-tier Terminal Block Type
GX-@D16@1/OC1601
High-speed digital I/O terminal with the
screw type terminal block for EtherCAT
communications
• Detachable screw terminal block facilitates the maintenance.
• The expansion unit can be connected.
(One expansion unit per one I/O terminal unit.)
Input/output point can be flexibly increased depending on the
system.
• Input response time can be switched for high-speed processing.
• Selectable node address setting methods: setting with rotary
switch and with tool software.
When setting the nodes with rotary switch, setting is easy and
node identification becomes possible for maintenance.
Expansion Units
One Expansion Unit can be combined with one Digital I/O Terminal (GX-ID16@1/OD16@1/OC1601). The following Expansion Units are available.
They can be combined in various ways for flexible I/O capacity expansion.

Precautions for Correct Use
•
With a current of between 2 and 3 A (8 to 10 A per common), either ensure that the number of points per common that simultaneously turn ON does not exceed
4 or ensure that the ambient temperature does not exceed 45
°C.
Also, there are no restrictions if the current does not exceed 2 A (8 A per common).
•
The rated current is the value for assuring normal operation, and not for assuring durability of the relays. The relay service life depends greatly on factors such
as the operating temperature, the type of load, and switching conditions. The actual equipment must be checked under actual operating conditions.
