Description
The Minco TI334 is a two-wire, loop-powered digital meter that accepts a 4 to 20 milliamp DC
signal. The meter measures the input current and accurately displays the corresponding
temperature in °C or °F. The meter derives power from the current loop, so no external power
supply is required. With only a 2.8 volt drop across the meter, it can operate from lower-
voltage DC power supplies and you can connect the meter in series with other loop-powered
devices.
The TI334 case is a 3” X 5” Polycarbonate NEMA 4X electrical case with knockouts.
Wiring
Use this meter to monitor temperature anywhere from the control room to the sensing location.
Wire it into the current loop anywhere observing the +/- polarity of the loop. Remove screws
which hold the front cover in place. Pull terminal block off from PC board, screw wires onto
block then re-plug block onto board. On the meter, terminal 1 is positive and terminal 2 is
negative. Wiring in Figure 1 below is typical.
°F and the °C stickers are supplied and can be applied to the front of the case.
Most Minco transmitters can be mounted inside the meter’s housing.
