Ex telephone connection relay

[Type dTA3]

The dTA3 telephone connection relays can be used to switch up to two external devices separately with ring tone signals – such as a siren and a flashing light. The bridging of the calling pause can be set for each of the attached devices. Both the dTA3 are designed for permanent use and are suitable in their Ex variation forms for temperatures between -20 °C and +40 °C.
