The TTLM I/O load module is designed for critical force measurement applications where accuracy, extreme stability, and dependable noise rejection is essential

The signal conditioner is a load measurement device and is used as an analog output (+/- 10 VDC), from a peak hold circuit, to be used with such PLC families as Allen-Bradley & Siemens as well as other data acquisition systems. These systems will provide the display and alarm control functions.

The TTLM has high sensitivity levels that work well in an electrically "noisy" environment. It has two amplifier gain ranges (span ranges) and can accept either weak or strong signals from the load sensor.

The TTLM module is available either in an AC version [customer selectable between 110V and 220V] or a 24 VDC version, depending on the power source the customer wishes to use. The 24 VDC version is certified to be in conformance with European CE standards. Either version is available in one, two or four channels.

The TTLM is included in our tonnage kits. These kits include the TTLM (signal conditioner), PM Kits (strain gauge sensors) and the ladder logic and screen programming needed to include tonnage monitoring into your existing PLC logic.
