The Edwards SIGI-CRHI is a Signature Series high power control relay module with an integrated isolator, for Edwards EST4 (EN54) analogue addressable systems. Like other Signature relay modules it switches external equipment on command from the Signature loop controller, with the integrated isolator protecting the rest of the data loop from wiring shorts. It is listed in Edwards' EN54 version EST4 submittal guide (data sheet E85001-0710).
Key features
- High power control relay output
- Integrated line fault isolator
- All decisions are made at the module, giving very fast control panel response
- Signature Series intelligent device with on-board microprocessor (distributed intelligence)
- Self-diagnostics and history log stored in non-volatile memory
- Automatic device mapping by the Signature loop controller
- Fast, stable digital communication - shielded or twisted wiring is not required
Technical specifications
- Type: high power control relay module
- Isolator: integrated
- Data sheet reference: E85001-0710
- Signature loop controller: 3-SSDC2-E (single) or 3-SDDC2-E (dual) on the EST4 panel
