1/16 DIN Solid State Temperature Controller–
Relay Output–Solid State Output–For Heating
Model Numbers: TEC-901, TEC-902, TEC-905
Temperature controls in this series are designed to fit panel cutouts that are 1-25/32" (45mm)
square. 4-1/8" minimum depth is required to provide clearance for rear terminal connections. All
models have the following specifications in common:

- Page 2 The solid-state relays can be single or three-phase. The TEC-905 possesses universal line voltage capability from 90–264VAC. The TEC-901 and TEC-902, however, are not interchangeable between different line voltages; only the specified line voltage must be used. When wiring the thermocouple, make sure that the thermocouple and extension wire conform to the thermocouple type specified by the instrument.
