Omron, GX-[]D16[]1 / OC1601 Series

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.

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.
