Note:
• Each switch output can switch a maximum of 250-300 mA at 230 V.
• A relay must be used at these outputs to switch loads.
• The wiring of the mating CPC 14 socket can vary between kiln manufacturers! Non-observance can
result in damage to the controller and kiln.
2.6. Kiln contactor protection circuit
The coil of each kiln contactor should be suppressed with an RC circuit. RC circuits must be connected directly
across the coil terminals on each contactor. ROHDE kilns are delivered this way as standard. For kilns from other
manufacturers, suitable products are available as accessories from contactor manufacturers.
