Description
Overview
The Dwyer 26111 is a dual-output industrial process controller for temperature and process monitoring and control applications. It features two SSR (solid-state relay) outputs for independent proportional or on-off control loops, combined with selectable input options to accommodate thermocouples, RTDs, DC voltage, or DC current signals. The dual LED display shows both process value and setpoint simultaneously, making it ideal for applications requiring independent control of multiple systems in harsh environments.
Key Features
- Dual SSR outputs (Output A and Output B) for independent proportional or on-off control
- Selectable inputs: Thermocouple, RTD, DC voltage, or DC current
- Dual 4-digit LED displays (0.56" high) for process and setpoint values
- ±0.25% of span accuracy with ±1 LSB resolution
- Supply voltage options: 100–240 VAC or 132–240 VDC
- Alarm relay output (SPST, 3 A @ 240 VAC)
- NEMA 4X (IP66) front panel rating for corrosion and moisture resistance
- Operating temperature range: –10 to 55°C
Applications
- Dual-zone heating or cooling control
- Independent temperature and pressure control
- Cascading control systems
- Industrial process management with multiple control loops
- Food processing equipment with independent zone control
