Red Lion Controls TCU12004 Temperature Controller

Red Lion Controls TCU12004 Temperature Controller is a compact, 1/8‑DIN temperature control unit designed for panel mounting in industrial processes. It accepts RTD sensor inputs across common types (Type B, E, J, K, N, R, S, T) and provides reliable closed‑loop temperature control for heating and cooling applications. The unit features a NEMA 4X alarm for rugged environments and RS‑485 communications for remote monitoring or integration with host controllers, plus a VDC analog output for signaling to other equipment. Marketed as an HMI/PLC‑based temperature controller, the TCU12004 is well suited for applications such as ovens, furnaces, and other temperature‑critical processes where robust environmental sealing, sensor versatility, and digital communication are valuable. This Red Lion controller combines straightforward installation with durable construction to support continuous operation in demanding factory settings.
