The Omron NX-TC3405 Machine Automation Controller Temperature Control Unit provides 4 channels for multi-zone temperature regulation. Compatible thermocouples and resistance thermometers can be used as measurement inputs, while 4 voltage outputs provide SSR drive signals for connected control equipment. Standard Control operation and a 50 ms conversion time support regular temperature measurement and adjustment across the channels. The NX-TC3405 increases thermal-control capacity within an NX architecture by combining multiple temperature channels in one module. Its configuration complements the PLC temperature control range used across Omron machine control applications.
