Rack-mounted DCS Signal Conditioners 18-RACK  
THERMOCOUPLE CONVERTER  
(field-programmable)  
Functions & Features  
• Accepting direct input from a thermocouple and providing  
two standard process signals  
OUTPUT 1  
• Microprocessor based  
Voltage  
• Field-programmable T/C type and temperature range  
• Linearization  
6: 1 – 5 V DC (Load resistance 2000 Ω min.)  
• Burnout protection  
• High accuracy cold junction compensation  
• Loop testing via hand-held programmer PU-2x  
• Second channel output available at the front terminals  
and at the Standard Rack connector  
OUTPUT 2  
Voltage  
6: 1 – 5 V DC (Load resistance 2000 Ω min.)  
POWER INPUT  
Typical Applications  
DC Power  
• Ideal for quick spare part  
R: 24 V DC  
• High-accuracy cold junction compensation benefits narrow  
span measurements  
(Operational voltage range 24 V ±10 %, ripple 10 %p-p max.)  
• 0.1μA burnout sensing enables long distance transmission  
with minimum offset drifts  
[2] OPTIONS  
Burnout  
• Electric furnace (isolation)  
• No burnout type can connect to a single T/C in parallel  
with a recorder  
blank: Upscale burnout  
/BL: Downscale burnout  
/BN: No burnout  
RELATED PRODUCTS  
• Programming Unit (model: PU-2x)  
• PC configurator software (model: JXCON)  
Downloadable at M-System’s web site.  
A dedicated cable is required to connect the module to the  
PC. Please refer to the internet software download site or  
the users manual for the PC configurator for applicable  
cable types.
