Specifications
Mounting
Standard 35 mm DIN rail mounting with filtering
components.
Connections
Three 2-pin cage-clamp style connectors accept up to
12 AWG wire
Power Requirements
Input Current: 4-20 mA DC (nominal)
Input Voltage: At 20 milliamps DC, 2 volts above
input voltage required by the field instrument
(2 volt drop across filter at 20 milliamps DC)
Ambient Operating Temperature
-40 to 85_C (-40 to 185_F)
Ambient Relative Humidity
5 to 95%
Electromagnetic Compatibility
Meets EN 61326-1 (First Edition)
Immunity—Industrial locations per Table 2 of
the EN 61326-1 standard. Performance is
shown in table below 1.
Emissions—Class A
ISM equipment rating: Group 1, Class A
Dimensions
75 mm (3 inches) long by 12.5 mm (0.5 inches) wide
by 60 mm (2.4 inches) deep
Approximate Weight
0.1 kg (4 oz)
Option
HF341 communications tap: Standard 35 mm DIN rail
mounting without filtering components (straight
through with capacitor blocking on COMM
terminals). In case of an accidental short circuit across
the COMM terminal, a capacitor blocking circuit
prevents disruption of the 4 to 20 mA DC control
signal.
