Output Signal:
4 to 20 mA DC (maximum load resistance 550 Ω)
Average-value Output; 3 points
(Note) Number of average-value output is 2 when suffix code “ -F” (FOUNDATION Fieldbus communication) is
selected.
(Note) When the individual insulation is specified, three points of average-value output and individual output are
insulated, but, between the three points of average-value are not insulated.
Independent Output; Output to each channel
Common isolation / Individual isolation selectable.
(Note) Used exclusively for communication when suffix code “ -F” (FOUNDATION Fieldbus communication) is
selected.
Digital Communication: FOUNDATION Fieldbus
HART; 250 to 550 Ω, depending on number of field devices connected to the
loop (multi-drop mode).
(Note) HART is a registered trademark of the HART Communication Foundation.
Contact Output:

Normally open / normally closed selectable
Common Contact Output; 5 points, Four of the output points can be selected to either normally
energized or normally deenergized status.
Contact output 5 is normally energized.
Contact Output for Individual Channel Fail; Output to each channel, Normally energized.
Solenoid Valve Contact Output: Contact capacity 30V DC 1A, 250V AC 1A, voltage free contacts,
DC 24V power supply (option). Maximam DC 300 mA
Contact Input:
2 points, voltage free contacts
Ambient Temperature: -5 to +50°C
Storage Temperature: -20 to +70°C
Humidity Range:

Category based on IEC 61010: II (Note)
Pollution degree based on IEC 61010:2 (Note)
Note: Installation category, called over-voltage category, specifies impulse withstand voltage. Category II is for electrical
equipment.
Pollution degree indicates the degree of existence of solid, liquid, gas or other inclusions which may reduce dielectric
strength. Degree 2 is the normal indoor environment.
