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)
