MODEL: 18TS 18TS SPECIFICATIONS ES-1812 Rev.7 Page 1/4 http://www.m-system.co.jp/ Rack-mounted DCS Signal Conditioners 18-RACK THERMOCOUPLE CONVERTER Functions & Features

• Accepting direct input from a thermocouple and providing two standard process signals
• 5-segment linearization
• Burnout protection
• High-accuracy cold junction compensation
• Second channel output available at the front terminals and at the Standard Rack connector Typical Applications
• High-accuracy cold junction compensation benefits narrow span measurements
• 0.1 μA burnout sensing enables long distance transmission with minimum offset drifts
• Electric furnace (isolation)
• No burnout type can connect to a single T/C in parallel with a recorder MODEL: 18TS–[1]6[2]–R[3]
