PR515 module in horizontal DIN rail enclosure, front view with pluggable screw terminals

0-5 V to relay, adjustable limit and hysteresis, with OLED display

Article number PR515x601

The PR515x601 compares a 0-5 V signal, for example from a pressure sensor or ratiometric sensor, with a set limit and switches a relay contact when it is exceeded. The hysteresis prevents the relay from chattering around the limit. You choose whether the relay switches on above or below the limit. The OLED display shows the current value and the relay state.

Supply 12 and 24 V DC, operating range 11 to 30 V DC
Input 0-5 V DC
Output relay contact (normally open)

Setup

Connect the supply, the 0-5 V source and the relay contact according to the wiring diagram supplied with the module.
On the display, set the limit and the hysteresis, and choose whether the relay switches on above or below the limit.
Check the current value and the relay state on the display and store with SAVE.

Application

Using a pressure or level sensor with a 0-5 V output as a switch
Switching an alarm or signal lamp at too high or too low a value
Switching a compressor or pump at a set pressure

PR515 series: controllers and converters with OLED display

The modules in the PR515 series have an OLED display and push buttons, so they can be set up without a computer and show the current values of inputs and outputs. They run on 12 and 24 V DC systems. Most versions can be extended on request, for example with an extra relay output, a PWM output, a bus connection (CAN bus or Modbus) or a different sensor input.
