PNOZ s8 Safety relay PNOZ s8 The unit meets the requirements of EN 60947-5-1, EN 60204-1 and VDE 0113-1. The contact expansion module is used to increase the number of instantaneous safety contacts available on a base unit. Base units are all safety relays with feedback loop monitoring. The category that can be achieved in accordance with EN ISO 13849-1 depends on the category of the base unit. The contact expansion module may not exceed this.

PNOZ s8 Wiring Please note: } Information given in the "Technical details" must be followed. } The outputs 13-14, 23-24 are safety contacts. } Semiconductor output Y32 should not be used for safety circuits! } To prevent contact welding, a fuse should be connected before the output contacts (see technical details). } Calculation of the max. cable length lmax in the input circuit: Rlmax = max.
PNOZ s8 } } Feedback loop – with PNOZsigma base unit: The feedback loop is connected and evaluated via the connector. – without PNOZsigma base unit: Feedback loop does not need to be monitored because the contact expansion block monitors its own output contacts. Semiconductor output *Connect together the 0V connections on all the external power supplies Information If a base unit and a contact expansion module from the PNOZsigma range are linked via the connector, no additional wiring is necessary.
PNOZ s8 Error indicators Fault Diagnostics: Internal error, unit defective } Remedy: Switch supply voltage off and then on again, change unit if necessary. Faults - malfunctions } Contact malfunctions: If the contacts have welded, reactivation will not be possible after the input circuit has opened.
