MODEL

Telemetering System

TMA

Functions & Features

• Transmitting 1-point analog signal (water level,

pressure, flow or ingredients analysis) through NTT

(Nippon Telephone & Telegraph) personal telecom-

munication line of 50 b/s • Both transmitter (TMA-

S) and receiver (TMA-R) modules are approved of

Technical Requirements Compliance Approval by

Japan Approval Institute for Telecommunications

Equipment • Approval No. M90-N239-0 (TMA-S),

M90-N240-1 (TMA-R) • No interference by induc-

tion noise • Output circuit isolated from input and

power circuits • Compact plug-in construction easy

to install and maintain
