SELECTION GUIDE: Trip amplifiers

Select from: <Single channel> <Dual channel> <Three channel>

PLEASE NOTE with most trip amps, other inputs within the
following ranges can be provided.
Current from 0-1mA to 0-30mA, Voltage from 0-1V to 0-250V.

CURRENT LOOP INTEGRITY FEATURE:
with B12, 107 and 112 type trip amplifiers the current input loop
is maintained when the module is unplugged.

Only the B12-TT and D16-T are microprocessor based.
