Description

IO952NI Apollo Twin IO Unit is the new twin input/output unit which provides the function of two Input/Output units within one enclosure. The two units are electrically independent of each other. There is a DIL switch on each unit to set the address. Both units provide supervision of one or more normally open contacts connected to a single pair of cables and a set of changeover relay output contacts.

Mechanical Construction

The IO952NI Apollo Twin IO Unit is available in the new faceplate style enclosure. It is designed to be surface mounted to the wall and consists of 3 parts:

  • a back box with knock-outs for cable entry
  • a PCB assembly
  • a protective front cover

 

Ease Of Installation

Improved design for ease of wiring meaning faster installation – unit can be fitted to back-box before wiring is connected. Color coded terminal blocks for easier identification (green for loop wiring, yellow for mains wiring, grey for inputs and low voltage relays).
