The Dwyer Instruments / Love Controls 26133-926-934 is a microprocessor-based temperature and process controller from the 2600 Series. It delivers precise monitoring and control across industrial heating, cooling, and process applications through universal sensor inputs and configurable control logic. The unit accepts thermocouples (J, K, E, T, L, N, B, C, S, R), RTDs (100Ω Pt NIST, 100Ω Pt DIN, 120Ω Ni Industrial, 1000Ω Pt DIN), differential inputs (-10 to +10 mV DC), and process signals (0 to 20 mA DC, 0 to 10 VDC).
## Technical Specifications
• **Input Types:** Thermocouple (J, K, E, T, L, N, B, C, S, R); RTD (100Ω Pt NIST, 100Ω Pt DIN, 120Ω Ni Industrial, 1000Ω Pt DIN); Differential (-10 to +10 mV DC); Process (0 to 20 mA DC, 0 to 10 VDC)
• **Power Supply:** 24 VDC isolated, regulated output for 4-20 mA transmitters
• **Input Voltage:** 100-240 VAC, 132-240 VDC
• **Display:** Digital
• **Enclosure Rating:** NEMA 4X (IP65) front panel
• **Output 1/3:** Switched 15 VDC standard
• **Option 934:** Analog retransmission 0 to 20 mA DC (scalable to 1-5 mA, 4-20 mA)
• **Option 936:** Analog retransmission 0 to 10 VDC (scalable)
## Key Features
• Four password-protected security levels for data integrity
• 16-segment ramp/soak programming with program end control
• Self-tune capability with manual PID adjustment and preset PID responses
• Front panel programmability
• Isolated 24 VDC power supply for transmitter operation
## Typical Applications
Temperature monitoring and process control in industrial environments requiring multi-input flexibility, data security, and programmable thermal profiles.
## Compatibility & Integration
Use 16 AWG or larger conductors rated 75°C minimum (copper only) for supply connections. Thermocouple, RTD, and Class 2 signal wiring must not share conduit with power leads. Extension leads must match thermocouple type.
