Analogue Dual Input Module CHQ-DIM2(SCI)

Model CHQ-DIM2(SCI) is a Dual Input Module designed to interface to a variety of inputs such as door contacts, sprinkler flow/door switches and plant equipment. Also available as a DIN Rail mountable version; both models feature an integral short-circuit isolator.

A back box is also available (CHQ-BACKBOX) which, when used in conjunction with the CHQ-DIM2(SCI), increases the IP rating to IP65.

  • Single Loop Address
  • Loop Powered
  • 2 Independent Inputs for Monitoring of Volt Free Contacts
  • Each Input can be Configured to Monitor either Normally Open or Normally Closed contacts
  • DIN-Rail version available
  • Both models feature an integral SCI
  • Both models approved by LPCB
  • SIL Level 2 approved variant available
