Dimensions (wxhxd)
W x H x D: 146 mm x 42 mm x 42 mm
(dimensions in mm 25.4 = 1 inch)
Software
Internal software for reading data from HART field devices and communicating over WirelessHART and/or Bluetooth®
Operation
Integral via DIP-switches,
Cell Phone configuration via SmartBlue App and Bluetooth®,
Field Xpert configuration via Bluetooth® or HART-modem,
PC configuration via FieldCare and HART-modem,
PC configuration via FieldCare and WirelessHART Gateway
Operating Voltage
24 V DC (min. 4 V DC, max. 30 V DC): min. 3.6 mA loop current required for start-up
Voltage drop if internal HART communication resistor is deactivated:
3.2 V in operation, < 3.8 V at start-up
Voltage drop if internal HART communication resistor is activated (270 Ohm):
< 4.2 V at 3.6 mA loop current, < 9.3 V at 22.5 mA loop current
