Understanding the Eliwell SB655 C is essential for refrigeration technicians and industrial maintenance teams who manage temperature-controlled environments. While these units are known for their longevity, finding a comprehensive "repack" or condensed guide for the SB655 C can be difficult since many legacy manuals are out of print.
| Terminal | Description | | --- | --- | | 1-2 | Power supply (24V AC/DC) | | 3-4 | Sensor input 1 ( thermocouple or PT100) | | 5-6 | Sensor input 2 (optional) | | 7-8 | Relay output 1 (heating/cooling) | | 9-10 | Analog output (optional) |
The repack includes a for common alarm codes: - E1 / E2 : Probe 1 or 2 open/short circuit → Check wiring or replace probe. - HA / LA : High/Low temperature alarm → Ventilation or door switch issue. - EE : Internal EEPROM failure → Replace controller.
A quality transforms the controller into an intuitive tool. You get:
