General Notes:

Many step controllers applications may be upgraded to use Selectronix controllers, especially when the capabilities are supplemented with those of a programmable electronic thermostat.  

Contact our Tech Support to determine if your application may benefit from an integrated solution!  

Note 1:   Series 4000

bulletStandard board size contain 4 or 8 relays.  The quantity to put in service is field-configurable.
bulletStandard field-selectable input voltage and current ranges, plus User-defined Input voltage or current  
bullet Up to 32 stages by cascading identical units, field-configurable as expansion units.
bulletIntegral Load Limit input limits peak demand
bulletProvides an integral 0-10VDC vernier output, with indicating LED (available on SLC4000-4-01, SLC4000-8-01, SLC4024-4-01, or SLC4024-8-01)
bullet120 VAC control power  (For 24VAC/DC input power order SLC4024-4 or SLC4024-8)
bullet120VAC,  240VAC, or 24VAC contactor coil
bulletOpen board with standoffs.  Optional SLC4010, NEMA 4X enclosure with SLC4000-ready back panel is available.

 

Note 2:   2100 Series

bulletFixed number of relays.  
bullet2 board sizes.  The small board accommodates from 1 to 6 relays, while the large board accommodates from 1 to 12 relays. 
bulletWith the maximum of 2 Expansion boards, the maximum stages is 36.
bulletSee the ‘2100 Series Ordering Guide’ to select the applicable part number. 
bulletNo vernier output signal is provided, use Series 4000, if required.
bulletNo direct thermistor input compatibility, use external thermostat.
bulletField selectable inputs of 135 ohm, 4-20ma, 2-10V.  0-10V input available by special order.
bulletProgressive sequencing, if Linear sequencing is required, use Series 4000  
bullet120 VAC control power  
bulletFor 120 VAC or 24VAC contactor coil
bulletFor 240 VAC contactor coil,  special order for 240VAC or use Series 4000

 

Note 3:  SLC4000-4, SLC4000-8

bulletInput power is 120VAC instead of 24 V AC/DC 
bulletRelay output vs. Triac output
bulletVernier output is 0-10V analog (available on SLC4000-4-01 or SLC4000-4-03)

Note 4:  2100 Series is compatible, see Series 4000 for new designs

Note 5:  2100 Series is compatible with special order for 0-10V, see Series 4000 for new designs  

Note 6:  

  1. This is a functional replacement when combined with either an external slidewire or electronic thermostat.  This may be an electronic unit such as a Honeywell T775 model, or a non-electronic slidewire unit such as a Honeywell T991A model. The original controller uses a thermistor sensor as the temperature sensor .  

  2. Expansion (slave) units require a compatible expandable controller.

  3. Indeeco Series 204 and 205 have an enclosure.  SLC2100 and SLC4000 are open boards.  If an enclosure is required, procure a separate enclosure for SLC211.  For SLC4000 order SLC4010, NEMA4X enclosure, which is available separately.

  4. Call tech support to verify suitability for the specific application.   

                 

Note 7: SLC2108 for systems with 8 total relays.  Use SLC2108X for systems with more than 8 relays, and select an expansion board SLC215x to fulfill balance of system relays. For instance, a 12 step system order an SLC2108X and SLC2154, or for  a 16 step system order an SLC2108X and an SLC2158.  The connecting cable is included with the expansion board.

Note 9: . The replacement unit requires an external temperature, pressure, or electronic controller that provides a suitable control signal. 
Note 10: Verify that the temperature or pressure controller is a 135 ohm slidewire device, or one that provides 2-10VDC, 0-10VDC or  4-20ma.  Examples of acceptable controllers are Honeywell L91, T921, or T991   Honeywell T775 electronic controllers also provide a compatible signal to drive the Selectronix step controllers.
Note 11: Cam Mini-Trailer boards are obsolete, so both main controller and trailer board must be replaced.  Determine the total number of relays on both boards to determine a suitable replacement.  Either SLC2100 series or Series 4000 step controls are suitable replacements
