The OTT2 unit converts mV input signals from a thermocouple into light pulse reections, and transmits them to the OTR2  
unit via €ber optics cable (A), while the OTR2 converts the light pulse reections into analog signals and output them to a  
temperature controller.  
The OTR2 transmits also ON-OFF control signals from the controller in the same manner via €ber optics cable (B), to the  
OTT2 unit while produces voltage pulse signals for driving the SSR for the heater.  
The SSR must accept a DC input and have zero-cross function.  
Specifications are subject to change without notice.
