The TMZ (TPRG)
The TMZ
The TMZ is a PC-Programmable, user-configurable,
signal converter. It has a digital output and retains the
high accuracy of an Analog to Digital converter without
the limitation of low resolution which is associated with
analog outputs. The multi-drop nature of the RS-485
port allows the connection of up to 32 units on a single
drop of cable that consists of two pairs of wires. The
TMZ has a READY LED to indicate the health of the
unit and an INPUT LED to indicate status.

of our instruments to track all information on each
