Control Mode
• On-Off
• Nominal switching hysteresis:
Type J thermocouple; 1.7°C (3°F);
Type K thermocouple; 2.2°C (4°F)
Operator Interface
• 76 mm (3 in.) dial scale calibrated to compensate for sensor
non-linearities
• Dual °C and °F scales
• D-shaft pot and adjustable ratchet knob
Input
• Thermocouple with automatic cold junction compensation
• Sensor may be isolated or grounded
• Sensor break protection de-energizes output
Output
• Electromechanical relay with contact suppression, 3A, SPST: 3A
@ 230V~ 3A @ 30V Î (dc), 125VA pilot duty @ 120 or 230V~
• Solid-state relay, Form A, 0.5A @ 24V~ min., 230V~ max.,
opto-isolated burst fire switched, without contact suppression.
Off state output impedance is 31M
Ω
.
• Switched dc signal provides a non-isolated minimum turn on
voltage of 3V Î (dc) into a minimum 500W load maximum on
voltage not greater than 28V Î (dc) into an infinite load.
Accuracy
• Calibration accuracy and sensor conformity: ±1% of span, at 25°C
± 3°C (77°F ±5°F) ambient and rated line voltage ±1%
• Set point accuracy: ±2% of dial scale
• Accuracy span: 540°C (1000°F) minimum
• Temperature stability: 9µV/°C (5µV/°F) ambient, maximum
referred to the input
• Voltage stability: ±0.01% of span per % of rated line voltage

SATISFACTION
The Watlow Series 101 is an on-off temperature
controller that comes in three common temperature
ranges or can be custom ordered to meet your require-
ments. The input sensor can be either Type J or K
thermocouple. The setpot is integral and has both degree
Celsius and Fahrenheit scales.
