PNOZ s7.1 Safety relay PNOZ s7.1 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 s7.1 Control cabinet installation } The safety relay should be installed in a control cabinet with a protection type of at least IP54. } Use the notch on the rear of the unit to attach it to a DIN rail (35 mm). } When installed vertically: Secure the unit by using a fixing element (e.g. retaining bracket or end angle). Push the unit upwards or downwards before lifting it from the DIN rail. Expansion options Please note the max.
PNOZ s7.1 Please note the max. power consumption of the contact expansion modules (see technical data PNOZ s7.1). Expansion options : Contact expansion module PNOZ s7.1 with terminator : Contact expansion module PNOZ s7.2 : Expansion module PNOZ s7, s8, s9, s10, s11 as a terminator : Base unit : Contact expansion module PNOZ s7.1 : Contact expansion module PNOZ s7.2 : Contact expansion module PNOZ s7.1 : Contact expansion module PNOZ s7.2 : Contact expansion module PNOZ s7.

PNOZ s7.1 } Connection to PNOZsigma base unit Base unit: Safety relay PNOZsigma The feedback loop is connected and evaluated via the connector. Information If a base unit and a contact expansion module from the PNOZsigma range are linked via the connector, no additional wiring is necessary. Do not connect A1 und Y1/Y2 to the expansion module! Operation LEDs indicate the status and errors during operation: LED on Status indicators In1 Channel 1 actuated. In2 Channel 2 actuated.
PNOZ s7.1 Service life graph The service life graphs indicate the number of cycles from which failures due to wear must be expected. The wear is mainly caused by the electrical load; the mechanical load is negligible. Example } Inductive load: 0,2 A } Utilisation category: AC15 } Contact service life: 2,000,000 cycles Provided the application requires fewer than 2,000,000 cycles, the PFH value (see technical details) can be used in the calculation.
