Details

The RTA421 limit switch from Endress+Hauser is used for monitoring and safeguarding industrial processes. The device evaluates current signals (0/4...20 mA) and voltage signals (0/2 to 10 V) and switches two independently operating relays at the output if previously defined limit values are exceeded or not reached. Both limit values can be read simultaneously in the display. Applications, e.g. pump controls in wastewater technology, level monitoring in tanks can thus be implemented at low cost.
