Dwyer Instruments 15111 Temperature Controller

Overview

The Dwyer Instruments 15111 is a compact, panel-mounted temperature controller designed for precise temperature regulation in industrial and laboratory applications. It accepts thermocouple or RTD inputs and provides solid-state relay or relay output for direct equipment control. The front panel is sealed to NEMA 4X (IP65) standards for use in wet or corrosive environments.

Key Features

• Output: Solid-State Relay (SSR) or mechanical relay (SPST)
• Display: 4-digit, 7-segment 0.3″ high LED display
• Accuracy: ±0.25% of span ± 1 least significant digit
• Status indicators: Set Point and Alarm LEDs, °F/°C selector
• Power supply: 100–240 VAC (50–400 Hz) or 132–240 VDC, 5 VA maximum
• Operating temperature: 14–131°F (-10 to +55°C)
• SSR output: 3.5A @ 240 VAC max
• Relay output: 3A resistive, 1.5A inductive @ 250 VAC
• Sensor break protection: De-energizes control output on sensor failure
• Alarm output: Optional relay, isolated from main output
• NEMA 4X (IP65) front panel rating
• Weight: 227 g (8 oz)
