Wieland Electric supplier in Romania
Safety relays and connection terminals for panels
Headquarters: Bamberg, Germany
Who is Wieland Electric and what does it make?
Wieland Electric is a German manufacturer of safety and connection technology for electrical panels and industrial machines, based in Bamberg. The safety range covers basic safety relays, versions with a time delay function, contact expansion relays and motion monitoring relays, alongside programmable safety controllers from the SAMOS Pro family. On the connection side, the company makes terminal blocks of the selos generation (with screw or push-in connection). For the Romanian market we can quote from both the safety relay range and the connection terminal range for electrical panels.
What sets Wieland Electric apart in safety relays is the performance level reached (up to PL e according to ISO 13849 and SIL3) combined with its own range of connection terminals, which means an electrical panel can be fitted entirely from the Wieland range, from functional protection to the physical connections. Among safety relays and controllers, Wieland Electric also offers motion monitoring relays with standstill detection without an additional sensor. The new selos terminals reduce the space taken up in the panel by up to 66% in the three-level version compared with the previous generation.
The Wieland Electric range comes into play where functional safety certification is required for emergency stop or guard door monitoring, and where an existing panel is being upgraded with more compact connection terminals.
What do we supply from the Wieland Electric range?
| Product | Description |
|---|---|
| Basic Safety Relays | Relays for monitoring a single safety function, with switching capacity of up to 8A and safety rating PL e/SIL3. Typical application: emergency stop or guard door monitoring on an industrial machine. The customer must specify the safety function monitored and the supply voltage. |
| Safety Relays with Time Delay | Version of the basic safety relays with an output delay function, useful for controlled stop sequences. Typical application: staggered stopping of several motors on an emergency command. Requires the desired delay time and the associated safety function to be specified. |
| Motion Monitoring Relays | Relays dedicated to monitoring motor speed or standstill, with standstill detection without an additional sensor and compatibility with HTL encoders. Typical application: confirming that a spindle has stopped before a guard door is opened. The customer must indicate the motor type and the speed signal available. |
| Selos Connection Terminals | Connection terminals for electrical panels, available in screw version (selos WTN, cross-sections 1.5–240 mm²) or push-in version (selos WTPN, cross-sections 1.5–16 mm²), with a compact multi-level design. Typical application: wiring an industrial electrical panel. Requires the conductor cross-section and the connection type required to be specified. |

How do we supply Wieland Electric in Romania?
For the Wieland Electric range we work from the manufacturer's technical documentation; exact availability is checked case by case for each code. We source safety relays, SAMOS Pro controllers and selos connection terminals to order, through European supply channels, usually in 1–4 weeks from order confirmation. For a correct quotation we need the safety function monitored or, for terminals, the conductor cross-section and the connection type required. Immediate availability is not something we can assure for every reference in the range.
Certification of a complete functional safety application and design of the circuit are carried out with a safety engineer on the customer's side.
Frequently asked questions about Wieland Electric
What products does Wieland Electric make?
Wieland Electric makes safety relays for industrial machines, SAMOS Pro programmable safety controllers and connection terminals for electrical panels from the selos range. It is a German manufacturer specialising in safety and connection technology, based in Bamberg.
How do I choose the right Wieland Electric safety relay?
The choice depends on the safety function monitored (emergency stop, guard door or motor speed), the performance level required (PL e/SIL3) and the switching capacity needed. For more complex logic, a SAMOS Pro controller is recommended instead of a simple relay.
What is the selos series from Wieland Electric?
Selos is the current generation of connection terminals for electrical panels from Wieland Electric, with screw and push-in versions and a compact multi-level design. The right cross-section and type are checked for each application.
What lead time do you offer in Romania for Wieland Electric safety relays?
We source Wieland Electric safety relays, SAMOS Pro controllers and connection terminals to order, through European supply channels, usually in 1–4 weeks from confirmation, depending on availability at the manufacturer.
What do I need to send for a Wieland Electric quotation?
We need the safety function monitored and the performance level required for relays, or the conductor cross-section and the connection type required for terminals, so that we can identify the correct reference in the range.
How do I request a Wieland Electric quotation?
Send the Wieland Electric code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
