Dräger Polytron Pulsar 2 maximum permissible power cable lengths
The following tables give the maximum cable lengths for differing worst case power supply voltages and core sizes.
In using this information please note that the worst-case (lowest possible) supply voltage should be used not the nominal stated.
The lengths stated are determined by the power supply cores. If cable size and distance become excessive it may be more economic to
install a local power supply. There is no practical limit on the distance for the signal cables, although the 4-20 mA loop resistance is lim-
ited to 500 Ω total.
Cable run in metres: To both Transmitter AND Receiver
Worst case supply: 20V 21V 22V 23V 24V 25V 26V...32V
