DATA SHEET

The 16A Series temperature / process controls set a new standard in 1/16 DIN power, flexibility, and value. This family of controls offers family interchangeability with different levels of features.

The 16A2 offers universal input (10 thermocouple types, 4 RTD types, voltage, and current), single or dual set point, alarm (optional), Fuzzy Logic, Self Tune, Peak / Valley indication, Per Cent Output indication, and Heater Break protection.

The 16A3 adds to this impressive list Auto / Manual capability, and 16 Segment Ramp and Soak with adjustable time base.

Options for the 16A2 and 16A3 include Process Output Retransmission (Voltage or Current), Remote Analog Set Point (Voltage, Current, Resistance), RS-232 Serial Communication, RS-485 Serial Communication, and 4-Stage Set Point.

Designed and built in the USA, the 16A family of controls offers the highest levels of features, function, and quality available today.
