Analogue Inputs; Inputs For Pt 100 Thermistors - HEIDENHAIN TNC 415 Technical Manual

11.1.3 Analogue inputs

The PA 110, the PL 410 and the PL 410 B (Id.-Nr 263 371 02) have 4 analogue inputs (± 10 V) and 4
inputs for Pt 100 thermistors. These inputs must be activated by a DIL switch on the PL 410 /
PL 410 B and a machine parameter in the TNC. When the analogue inputs are active, two outputs
(O61/O62 or O93/O94 on PL #2) and eight inputs (I120 to I127 or I248 to I255 on PL #2) of the PLC
cannot be used. (See chapter "Machine integration", section "Analogue inputs").
