IDENTIFYING THE SOLID STATE RELAYS
The firing mode for TE200S SSRs is Logic ON/OFF.
The SSR can be controlled by DC or AC logic signals (configured at the factory depending
on the order code).
The electronics of TE200S SSRs are self-supplied from the power voltage and do not require
external connections.
A TE200S SSR is equipped with:
• A ‘driver board’
• A ‘firing board’ which triggers thyristor firing.
The filter which provides immunity against electromagnetic interference is located between
the power phases.
The user terminal block below the SSR is used for input signal connection without needing
access to the inside of the unit.
A green LED, labelled ‘ON’, indicates thyristor firing and is located on the front facia.
TE200S SSRs are designed to be bulkhead or DIN rail mounted.
The 63A rated unit must be permanently fan-cooled.
The fan power supply is 115Vac or 230Vac (to be specified when ordering the SSR).
In the event of the SSR overheating, a thermal switch stops thyristor firing in the 63A rated
version of the TE200S.
Firing becomes possible again after return to nominal thermal conditions.
