HEIDENHAIN iTNC 530 HSCI - Further examination of position and speed encoders

314 HEIDENHAIN Technical Manual iTNC 530 HSCI
X112/X113 pin layout on PLB 62xx as of variant-03 and UEC 11x (FS):
(15-pin D-sub, triple-row)
Load capacity of output voltages of X112, X113:
 Socket 10, +24 V NC: max. 0.8 A
 Socket 5, +5 V NC: max. 0.8 A
The currents are total currents for X112 and X113 together; they are not the
output currents per connector.
Readiness of the TS at socket 3 is detected at a voltage of +8 V NC to +24 V
NC.
Note
The interface complies with the requirements of EN 60204-1:2006 for
protective extra-low voltage (PELV).

Danger
Please note that the outputs of connectors X112 and X113 are supplied
internally with 24 V NC and thus supply NC voltages derived from it at the
outputs.
For the entire HSCI system, the +24 V NC supply voltage is required to be
safely separated voltage. The +24 V NC supply voltage must not, under any
circumstances, be connected with the +24 V PLC supply voltage, because
this removes the double basic insulation.
