The safety relay meets the requirements of EN 60204-1 and IEC 602041 and may be used in applications with » E-STOP pushbuttons The safety relay is not suitable for noncontact barriers because 

a dynamic start is not possible the unit can be started during the delay-on de-energisation time.

## **up to Category 2, EN 954-1** PNOZ X1 

## **Function description** 

- Single-channel operation: no redundancy in the input circuit, earth faults in the reset circuit are detected. 

- Automatic start: Unit is active once the input circuit has been closed. 

- Manual reset: Unit is active once the input circuit is closed and then the reset circuit is closed. 

- Increase in the number of available contacts by connecting contact expander modules or external contactors/relays.

## **Wiring** 

Please note: 

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

- Outputs 13-14, 23-24, 33-34 are safety contacts, output 41-42 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.

E-STOP relays 

## **up to Category 2, EN 954-1** PNOZ X1 

## **Terminal configuration** 

## **Installation** 

## **Dimensions** 

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. Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing element (e.g. retaining bracket or an end angle).
