## **Unit description** 

Bestimmung/Gertebeschreibung Kontakterweiterungen Schalt_PNOZThe 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 954-1 and EN ISO 13849-1 depends on the cate- 

## **Safety features** 

Sicherheitseigenschaften Kontakterweiterungen allg_PNOZThe unit meets the following safety requirements: 

- The contact expansion module expands an existing circuit. As the output relays are monitored via the base unit's feedback loop, the safety functions on the existing circuit are transferred to the contact expansion module. 

- The safety function remains effective in the case of a component failure. 

- Earth fault in the feedback loop: Detected, depending on the base unit that is used. 

- Earth fault in the input circuit: The output relays de-energise and the safety contacts open.

][Verdrahtung_Si_unverz_1Hi_unverzPlease note: 

- Information given in the “Technical details” must be followed. 

- Outputs 13-14, 23-24, 33-34, 4344, 63-64, 73-74, 83-84, 93-94 are safety contacts, output 51-52 is an auxiliary contact (e.g. for display). 

- To prevent contact welding, a fuse should be connected before the output contacts (see technical details). 

- Calculation of the max. cable runs lmax in the input circuit: 

   - ������ 

- ����� 

- ������� 

Rlmax = max. overall cable resistance (see technical details) Rl /km = cable resistance/km 

- Use copper wire that can withstand 60/75 °C. 

- Sufficient fuse protection must be provided on all output contacts with capacitive and inductive loads.

## **Service life graph** 

Lebensdauerkurve_Relais_Text vor KurveThe service life graphs indicate the Lkv **e** bnsda **ur** number of cycles from which failures 8 due to wear must be expected. The i=) wear is mainly caused by the electrical x© 10000 — load; the mechanical load is negligible. 

> Lebensdauerkurve_Relais_Text nach Kurve_SIF Bsp **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. 

To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With contactors, use freewheel diodes for spark suppression.

No. stands for order number. 

Si-Kennzahlen_Zusatz_Relais_Lebensdauer_PDBIt is essential to consider the relay's service life graphs. The relay outputs' safety-related characteristic data is only valid if the values in the service life graphs are met. 

The PFH value depends on the switching frequency and the load on the relay output. If the service life graphs are not accessible, the stated PFH value can be 

used irrespective of the switching frequency and the load, as the PFH value already considers the relay's B10d value as well as the failure rates of the other components. 

All the units used within a safety function must be considered when calculating the safety characteristic data. 

## Si_Kennzahlen_Erläuterung_2 **INFORMATION** 

A safety function's SIL/PL values are **not** identical to the SIL/PL values of the units that are used and may be different. We recommend that you use the PAScal software tool to calculate the safety function's SIL/PL values. 

The standards current on **2006-10** apply.
