The Omron NX-TC3407 Machine Automation Controller Temperature Control Unit supports heating and cooling control across 4 temperature channels. It accepts compatible thermocouples and resistance thermometers for temperature measurement and provides 8 voltage outputs for SSR drive. These outputs enable separate heating and cooling control actions across multiple thermal zones. A 50 ms conversion time supports regular processing of measured temperature values during operation. The NX-TC3407 provides a dedicated configuration for systems requiring both heating and cooling functions. This capability extends the PLC temperature control range within Omron machine automation systems.
