Front connector assignments
Voltage or current input
or connection of two-wire transducer
Resistance thermometer
Two-wire transducers can only be connected in the 500 mV mode.
Connect L- to the central ground point (reference potential).
1)
Observe permissible potential difference between sensor and reference
potential of modules or between sensors.
2)
Two-wire transducer
3)
Only required to switch off the tripping current without broken wire detection;
(0 V at common ground point with L-).
