Series-2600

Supported Applications

The Dwyer Series 2600 Microprocessor Based Temperature/Process Controllers are designed for temperature and process control applications. The series features a universal input capable of accepting thermocouple types J, K, E, T, L, N, B, C, S & R; RTDs including 100Ω Plt. NIST, 100Ω Plt. DIN, 120Ω Ni Industrial, and 1000Ω Plt. DIN; differential input (-10 to +10 mV DC); and process inputs (0 to 20 mA DC, 0 to 10 VDC). Standard features include Self-Tune, Fuzzy Logic, fully adjustable PID, Auto/Manual control with bumpless transfer, percent output indication, peak and valley indication, loop break protection, and a front panel activation key.

Operating Conditions & Performance

The Series 2600 operates within an ambient temperature range of 14 to 131°F (-10 to 55°C). Accuracy is specified as ±0.25% of span, ±1 least significant digit. For process inputs, the display is fully programmable from -1999 to +9999 with a selectable decimal point location; most thermocouple and RTD inputs can show whole or tenth degree displays. The unit includes a standard 24 Volt isolated, regulated power supply designed to operate most standard 4-20 mA transmitters.

Physical dimensions are listed as height: 3-19/32 [91.3], width: 4-9/16 [115.8], and depth: 17/32 [13.5]. The enclosure rating is NEMA 4X (IP65). Weight is 13 oz (369 g).

Power Supply

• AC: 100 to 240 VAC nominal, +10%-15%, 50 to 400 Hz, single phase
• DC: 132 to 240 VDC +10% -20%

Configuration Options

The Series 2600 is available with single or dual setpoint outputs and can be programmed for on-off, PID, heat/cool, or latching alarm modes. All outputs are isolated from the inputs.

Outputs & Signals

• Relay: 10 Amp relay output available (Output A and/or Output B).
• Current: 0-20 mA DC, scalable into 600 ohms maximum load resistance.

Options & Accessories

• -924: Remote Set Point 0 to 10 VDC
• -926: Remote Set Point 0 to 20 mA
• -928: Remote Set Point 0 to 10 K Ohms
• -934: Process Signal Output, Non-Isolated 0 to 20 mADC
• -936: Process Signal Output, Non-Isolated 0 to 10 VDC
• -992/-993: RS-XXX Serial Communications Love Link™ Protocol (RS-485 or RS-232)
• -995/-996: RS-XXX Serial Communications Modbus® RTV Protocol (RS-232 or RS-485)

Additional accessories include the MN-1 Mini-Node™ USB/RS-485 converter, LoveLinks III configuration software, and A-600 R/C snubber.

Key Product Differences

The series includes specific model configurations based on output combinations:

• Model 26130: Alarm enabled; Output A is Relay; Output B is None.
• Model 26150: Alarm enabled; Output A is Current; Output B is None.
• Model 26133: Alarm enabled; Output A is Relay; Output B is Relay.

Note: When switching inductive loads (relays, motors, solenoids), an R/C snubber should be used across the coil. For thermocouple input, extension leads of the same type designated for the specific thermocouple must always be used.
