INSTALLATION

Current consumption

•DC: Approx. 90 mA

Operating temperature: -10 to +55°C (14 to 131°F)

Storage temperature: -20 to +65°C (-4 to +149°F)

Operating humidity: 30 to 90 %RH (non-condensing)

Atmosphere: No corrosive gas or heavy dust

Mounting: DIN rail (35 mm rail)

Weight: 200 g (0.44 lb)

PERFORMANCE

Conversion rate / Conversion accuracy: 2 msec. / ±0.1%

Data range: 0 – 10000 of the input range

Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)

Response time: Conversion rate × 2 + scan time (0 – 90 %)

Scan time depends on the Final Satellite (FS) value of

Center IC (master) configuration and transfer rate (TBPS). It

is calculated with the following formula. Scan time = 354 ×

FS × TBPS (seconds)

E.g) When “Final satellite value = 63, transfer rate = 12

Mbps, scan time is = 354 × 63 × 1/12 M = 1.859 msec.

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 1500 V AC @ 1 minute (input to FLEX

NETWORK to power to FG)
