Water movement in a chemical plant

Application

Chemical plant  

Relays are the interface for various plant processes

Water is required for all manufacturing processes in chemical plants. For example, it can drive turbines or function as a heating medium. As such, the movement of the water is controlled by 24 V DC solenoid valves.

A PLC controls the solenoid valve while simultaneous feedback is required regarding the valve state. A challenge here is the limited space.

Solution

Application graphic: two relays switch four solenoid valves  

Two relays switch four solenoid valves

Phoenix Contact has a selection of compact relay modules for space-saving applications. The PLC-2R ... modules provide two independently-controllable relays in a slim 6.2 mm housing. This enables different functions to be realized in a particularly space-efficient way.

The use of two integrated relays means the user benefits from twice the channel density. On the output side, the two relays provide separate plus and minus potentials.

Your advantages

  • Particularly space saving, thanks to the slim overall width of just 6.2 mm
  • Double channel density, thanks to two integrated relays
  • Time-saving potential distribution, thanks to jumpers
  • Your choice of easy connection technology: screw, spring-cage or push-in connection technology
