DIGITROL II

The DigiTrol II uses a microprocessor-based,user-selectable control mode temperature control. The control features a digital dual output display for set point and process temperature indication. The automatic-tuning feature ensures increased temperature accuracy with minimum overshoot. Easy set-up and simple input commands make this control very “user friendly.” The load and the thermocouple receptacles are located on the front panel for easy accessibility.
Features automatic cold junction compensation and thermocouple break protection.

Furnished with an immersion thermocouple with 6"-long stainless steel probe.
Specifications
Electrical: Lighted on/off power switch with auxiliary LED indication, fuse protection,3-wire load receptacle, and 3-wire line
cord with molded plug.
Control Type: PID parameters with auto/manual mode option.
Accuracy: 0.1% of span.
Display: Dual, 4-digit LED.
Set Point: Up/down keys. °F or °C display,user selectable.

Lab Bench Case: Low profile cabinet,8"w x 6"d x 3-3/8"h.

RAMPTROL

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 4-20ma retransmit output for temperature recording and an RTD input. Information is stored in non-volatile memory.

Specifications
Control Mode: Single output. Optional retransmit of set point or process variable.
Four-file/24-step ramping or non-ramping, set-point control. Ramp-rate or timebased programming. Selectable control
status following power loss.
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.

Accuracy: 0.1% of span, temperature stability +/-0.2%°F/°F change in ambient.
Input: Factory set for thermocouple; grounded or ungrounded.
Lab Bench Case: 8"w x 8"d x 4 3/4"h.
