More and more components for automation technology are suitable for use in the field thanks to high IP protection and M12 connection technology. As a rule, they have semiconductor outputs with 24 V levels and maximum switching currents between 20 and 300 mA. If other voltages, higher switching currents or electrical separation are required, relays are a popular solution - for which, however, a detour via a control cabinet was necessary until now. With the relay adapters from ifm, field-compatible relays are now available which can be connected easily and reliably thanks to the M12 connection technology commonly used in the field.
