RTA421

Contactor with loop power supply for monitoring current or voltage signals

Highlights
  • LC display for alarm set points and bar graph
  • Input 1 x analog (U, I)
  • Output 1 x transmitter power supply
  • Relay output 2 x changeover contacts
  • Auxiliary power supply / Loop power supply 196...250V AC, 97...127V AC, 20...250 V AC/DC
Product Description

The RTA421 contactor monitors industrial processes for safe operation. The unit analyzes current (0/4...20 mA) and voltage signals (0/2...10 V) and switches two independent output relays if the values either exceed or undercut the preset alarm set points. On the display both limit values are indicated in parallel. The bar graph informs on the connected signal at any time. Applications include pump control in the waste water industry. Level measurement in silos can be economically achieved.

Fields of application
  • Plant and machine construction
  • Panel builders
  • Process monitoring
  • Process control
