PPE's RMA Series module 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 three discrete indicators for heat output, alarm, degree F/C
indication, manual and closed loop mode. RMA modules are available in 15 amp version and
are compatible with all previous "G" series mainframes.
RMA modules provide fully self-tuning, line voltage compensating, automatic closed-loop
temperature control over a wide range of operating conditions. A single chip microprocessor
performs all the proportional, integral and derivative (PID) control functions required to maintain
setpoint temperature. No operator calculations or presetting of values is needed.
