Analogue Dual Input Module CHQ-DIM

Features – 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 – “Smart-Fix” Housing System for flexibility – Available as DIN-Rail version – Both versions available with or without integral SCI

Model CHQ-DIM 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, with or without an integral short-circuit isolator.
A back box is also available (CHQ-BACKBOX) which, when used in conjunction with the CHQ-DIM, increases the IP rating to IP65.
