Industrial signals are loosely associated as process are 0-5VDC, 0-10VDC, millivolts DC and the most popular 20mA loops (e.g. 4-20mA). These are scaled as a range in engineering units e.g. 0-10VDC = 0-500 Litres Per Hour.
The Tracker Instruments that can accept ±20mA, ±10VDC and ±100mV are:
All of the above have as standard or can be fitted as an option:
All the instruments listed above can also connect directly to thermocouples and RTD temperature sensors making their inputs "Universal". |
