AutomationDirect SL4848-CR Temperature Controller

The AutomationDirect SL4848-CR is a 1/16-DIN SOLO standard temperature controller designed for single-loop process control. This 48 × 48 mm panel device features a two-line LED display and accepts multiple sensor inputs (current, voltage, RTD, or thermocouple). It provides a 4–20 mA analog control output and a primary switching path via a 5 A Form A SPST relay, plus two 3 A Form A alarm relays; all outputs are powered from 100–240 VAC, 50/60 Hz, with a nominal 5 VA consumption. In addition to its analog and relay outputs, the SL4848-CR supports RS-485 communications for digital integration, enabling Modbus RTU and ASCII protocols to connect with PLCs, HMIs, or SCADA systems. The device is RoHS compliant and is designed for compact, front-panel installation in control panels where space is at a premium. Typical uses include heating and cooling control in industrial ovens or furnaces, temperature regulation for process vessels, or laboratory/bench-top test setups that require reliable single-loop regulation with simultaneous alarm monitoring. Built for reliability in industrial environments, the SL4848-CR combines flexible input options, multiple output channels, and standard communication to streamline temperature control tasks in a compact 1/16-DIN package.
