West - P6700, P8700, P4700 Limit Controllers

  • High or low trip points
  • 5 amp latching limit relay
  • Remote reset option
  • Exceed and relay indicators

Product description

The West range of 6700, 4700 and 8700 have a programmable safety cut out with optional outputs for annunciators and alarms. A latched relay cuts power to your process if safe values are exceeded. These units must be reset before the process can continue. They have the improved Plus Series hardware and user interface for optimal ease of use.

Specification

Features:

 

 

Output configuration

Up to 3 possible, for latching trip relays, alarm/annuncator relays, 24VDC transmitter power supply
