The GB5 Programmable Temperature Controller requires a sending unit for each oven. Sending units for platinum thermocouples (Type R or S) are different from the standard Type K sending units.

Power Reqirements
3 watts at 110–120 volts A.C., 60 Hz, grounded outlet (220–240 volts, 50 Hz available)

Temperature Input for Each Oven
Type K: 32–2400°F (0–1300°C) or Type S or R: 50–3200°F (10–1700°C)
Automatic cold junction compensation
