Series RMA
The Athena Series RMA is a microprocessor-based,
single-zone temperature controller specifically
designed for runnerless molding applications.
It features an easy-to-use operator keypad, two LED
displays, and discrete indicators for heat output, alarm,
degree F/C indication, manual, and closed loop mode.
▲ Compatible with industry standards control
modules and mainframes
▲ Accepts Type J thermocouple
▲ Bumpless auto/manual transfer
▲ CompuStep® bake out feature prevents moisture
at startup
▲ Built-in loop break for open heater, shorted triac,
reversed or shorted thermocouple
▲ Open thermocouple break protection with jumperselectable shutdown or average power output
based on operation
▲ Preset alarms at 30°F (17°C)
▲ SafeChange™ “hot swap” feature allows safe
removal and replacement of module
▲ CE compliant
