ZT Series Tonnage Load Module

The ZT is a signal conditioner used with Allen-Bradley and Siemens PLC's for press tonnage measurement

The ZT Series tonnage load module is designed for critical force measurement applications where accuracy, extreme stability, and dependable noise rejection is essential. It is equipped with an LED bar-graph voltmeter for easy setup and diagnostic. The ZT is DIN rail mountable and is designed to interface with a PLC analog card and to display output through a human machine interface (HMI).

The ZT module is available in Single-Channel (the ZT-1 as pictured above) and in Four-Channels (the ZT-4 as pictured to the right).







Features

  ZT-1 ZT-4
Designed to work with strain gauge
  sensors and load cells. The ZT
  can also accept input from 4-20mA
  current output sensors or voltage
  output sensors.
Simultaneously provides normal peak,
  reverse peak, and track voltage
  outputs.
Simultaneously provides normal peak,
  reverse peak, and track 0-20mA current
  outputs.
 
Built-in threshold trigger simplifies
  installation. External probe trigger
  can also be used when situation
  required.
LED bar-graph voltmeter for easy setup
  and diagnostic.
Built-in 1 Mega Ohm calibration shunt
  resistor.
User selected external shunt resistor
  can be used for load cell applications.
 
x1 and x10 amplifier gain ranges to
  work with either strong or weak signal
  from the load sensor.
Auto-Zero can be selected using dip
  switches to compensate for zeroing
  errors caused by environmental changes
  such as temperature, humidity, and etc.
Electrical noise rejection filter can
  be enabled when situation required.
Plug-in connectors for easy wiring and
  installation.
Standard DIN Rail mount simplifies
  systems integration.
Modular with common bus design allows
  future upgrade and expansion.
CE Certified
