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.
