Autonics TZ4L-24R Digital Temperature Controller

Autonics TZ4L-24R is a 1/4‑DIN digital temperature controller with dual PID control, designed for precise regulation of process temperatures. It features a 4‑digit LED display and a relay output for reliable on/off control, along with two independent alarm outputs to flag out‑of‑range conditions. The TZ4L‑24R accepts sensor inputs from thermocouples or RTDs (types E, J, K, N, R, S, T, W), offering broad compatibility for a range of applications. It is powered from a 100–240 VAC supply (50/60 Hz) and is intended for front‑panel mounting on a 96×96 mm footprint (approximately 3.78 in square), commonly described as a 1/4‑DIN format. In terms of actuation, the relay output is rated for up to 250 VAC and 3 A, providing ample capacity for heating or cooling loads typical of small to medium industrial processes. Autonics lists TZ4L‑24R as discontinued in several regional catalogs, as part of the TZ4L family that includes multiple footprint and supply variants, reflecting its legacy role in dual‑PID temperature control technology.
