Miniature measuring amplifier

The miniature measuring amplifier TSA723 satisfies with a compact and rugged design. The housing fits optimally into the arrangement of terminal blocks in a control cabinet.

For mounting with double-faced adhesive tape or for the use in laboratories the measuring amplifier is available without rail-mounting adapter.

Connection is effected by plugs with screw terminals. This offers a very efficient wiring possibility.

Features

voltage output 0 to ±10V; optional current output 0-20mA or 4-20mA
ZERO and CAL adjustment by multi-turn potentiometer
input power supply of 24V DC, reverse-polarity protected
compact and robust aluminium housing
