– M20
Cable specification Permitted temperature range
• –40 °C (–40 °F) to +80 °C (+176 °F)
• Minimum requirement: cable temperature range ≥ ambient tempe20 K
Power supply cable
Standard installation cable is sufficient.
Signal cable
Current output
For 4-20 mA HART: Shielded cable recommended. Observe grounding concept of the plant.
Pulse/frequency/switch output
Standard installation cable is sufficient.
PROFIBUS DP
The IEC 61158 standard specifies two types of cable (A and B) for the bus line which can be used for
every transmission rate. Cable type A is recommended.
Cable type A
Characteristic impedance 135 to 165 Ωat a measuring frequency of 3 to 20 MHz
Cable capacitance <30 pF/m
Wire cross-section
>0.34 mm 2 (22 AWG)
Cable type Twisted pairs
Loop resistance ≤110 Ω/km
Signal damping Max. 9 dB over the entire length of the cable cross-section
Shielding Copper braided shielding or braided shielding with foil shield. When grounding
the cable shield, observe the grounding concept of the plant.
Modbus RS485
The EIA/TIA-485 standard specifies two types of cable (A and B) for the bus line which can be used
for every transmission rate. Cable type A is recommended.
Cable type A
Characteristic impedance 135 to 165 Ωat a measuring frequency of 3 to 20 MHz
Cable capacitance <30 pF/m
Wire cross-section
>0.34 mm 2 (22 AWG)
Cable type Twisted pairs
Loop resistance ≤110 Ω/km
Signal damping Max. 9 dB over the entire length of the cable cross-section
Shielding Copper braided shielding or braided shielding with foil shield. When grounding
the cable shield, observe the grounding concept of the plant.
EtherNet/IP
The standard ANSI/TIA/EIA-568-B.2 Annex specifies CAT 5 as the minimum category for a cable
used for EtherNet/IP. CAT 5e and CAT 6 are recommended.
