Fieldbus (pH): Four AI blocks assigned to pH, temperature, reference impedance, and glass impedance.
Fieldbus (ORP): Three AI blocks assigned to ORP, temperature, and reference impedance.
Fieldbus (pH and ORP): Execution time 75 msec. One PID block; execution time 150 msec.
Device type 4085. Device revision 1. Certified to ITK 4.5.
Minimum power supply voltage is 12 Vdc. Maximum power supply voltage is 42.4 Vdc (30 Vdc for intrinsically safe operation). Power supply voltage should cover the voltage drop on the cable plus the external load resistor required for HART communications (250 Ω minimum).
