Features and benefits
Snap on DIN rail mounting as standard with this product allowing easy additions & removals, allowing you the flexibility and portability you require.
240 of lightweight, durable plastic (glass fibre) reinforced thermoplastic. The structure is also ventilated meaning it dissipates heat quicker allowing the device to remain cool.
The material of the contact is a standard AgSn0. It has a positive action and is also self-cleaning.
Automatic or manual start button input allowing you further control over your device (optional monitored).
A feedback circuit as standard with this product allows the unit to detect any welding of the contact point, which is particularly useful in keeping the relay running instead of shutting down upon contact.
