Description
Overview
The Dwyer 26115 is a flexible industrial process controller for temperature and process monitoring and control applications. It features one SSR (solid-state relay) output for proportional or on-off control, combined with a 0–20 mA current output for remote signal transmission and SCADA integration. Selectable input options 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 integrated analog control and data acquisition in harsh environments.
Key Features
- Output A: SSR (solid-state relay) for proportional or on-off control
- Output B: 0–20 mA DC current loop for remote signal transmission (scalable into 600 Ω maximum)
- 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
- Systems requiring analog current loop signals for SCADA or remote monitoring
- Integration with distributed control systems
- Industrial process automation with remote feedback
- Remote pressure or temperature monitoring and transmission
- Systems requiring both local control and remote data acquisition
