1.3.3 Connections and Mounting
The Series RMB controllers are designed for installation in a Hot Runner
mainframe (or other compatible mainframe). Removal of an RMB controller
from the mainframe requires removal of a locking pin (standard controllers) or
locking screw (CE-compliant controllers).
1.3.4 Inputs
Thermocouple J or K
Supported Sensor Range 32 to 999°F (0 to 537°C)
1.3.5 Output
TRIAC, 15 amps at 120/240 Vac (30 amp optional), driven by optically isolated
interface circuit. Protected with a pair of 15 amp (or one 30 amp) field-
replaceable fuses. Instructions for replacing the fuses are in 6.3. Replacement
fuses must be Type F fast-acting 250 Vac fuses rated at 15 amps (or 30 amps).
A 15 amp (120/240 Vac) relay (30 amp optional) interrupts power to the heater if
the controller detects shorting of the TRIAC output or other system failures.
A ground fault detection circuit is also standard.
