Dräger Polytron Pulsar 2 Maximum Permissible Power Cable Lengths; Cable Run In Metres: To Both Transmitter And Receiver; Cable Run In Metres: To Transmitter Only - Dräger Polytron Pulsar 2 Technical Manual

Electrical Installation
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
