RampTrol Ramping Power Control w/ Type J Thermocouple

Item #: 20022

Normal Availability: 4-5 business days

Product Description

This microprocessor-based ramping control provides four-file/24-step program capability or easy-to-use non-ramping set-point operation. Ramping operations include four files with six steps each. Programming options include ramp-rate or time-based profiles, guaranteed soak deviation, program looping, and program status selection after power outage. Files may be linked to create a single, 24-step program. Also allows automatic setting of control parameters with little user input. RampTrol automatically sets the PID parameters (proportional band, reset/integral, and rate/derivative) through a "learning" sequence in the auto-tuning mode. The primary analog input is a thermocouple. The back panel features a nine-pin serial port for communication with a PC. A secondary output is available for cooling, along with a 4-20 ma retransmit output for temperature recording and an RTD input. Information is stored in non-volatile memory. See below for specifications.


  • Control Mode: Single output. Optional retransmit of set point or process variable.
  • Operator Interface: Dual, four-digit LED displays: upper, 0.4 inch (10 mm) for process (red); lower, 0.3 inch (8 mm) for set point (green). Mode, Hold/Run, Display, Up, and Down keys.
  • USB output for configuration of control and data acquisition.
  • Accuracy: 0.1% of span, temperature stability +/-0.2%°F/°F change in ambient.
  • Input: Factory set for thermocouple; grounded or ungrounded (request with order).
  • Ambient Temperature Range: 32-130 °F.
  • Lab Bench Case: 8" w x 6" d x 3-3/8" h.
  • Electrical rating: 15 A @ 120 V, 1,800 W or 10 A @ 240 V, 2,400 W.
  • Range: 0 to 816 °C, -200 to 1,1250 °C, or -200 to 399 °C.
  • Thermocouple Types: 120 V: universal (comes with a Type J; others sold separately; see item # 20080).
  • Ranges: Thermocouple dependent. With included type J: 0 - 750 °C.
  • Weight: 4.0 lbs (1.81 kg).

This item is available in 120 and 240 V versions.

NOTE: Effective 2023, the 120 V units now come with a universal thermocouple connector which means you can attach any thermocouple you want to cover a specific temperature range. The 240 V units are still sold in defined temperature ranges; the universal thermocouple feature will be coming to those versions at some point but we do not have a specific schedule yet
