Description

The Chromalox 2104 1/4 DIN Temperature and Process Controller is a low cost, high performance single loop controller that can be used for temperature, flow, pressure and level control applications. With universal sensor inputs and front panel operator setup, one 2104 controller can be easily field configured for a wide variety of applications, and simply reconfigured as application needs change. This makes it an exceptional choice for OEMs and distributors with multiple control needs, manufacturing facilities, testing facilities and testing applications.

Features

Five (5) Possible Outputs for Single Output or Heat/Cool Control, plus up to three Alarm or Event Outputs.

Universal Sensor Input accepts thermocouple, RTD or analog signals, provides 24 Vdc Output for loop power.

Self-Tuning with Fuzzy Logic optimizes PID control and minimizes overshoot.

Digital Input for remote switching of one of the following:

• PID1/PID2

• Remote/Local Setpoint

• Main/Auxiliary Setpoint

• Ramp/Soak Operation

• Manual/Auto Control

• Alarm Reset for Latching Alarms

16 Interval Ramp/Soak Program with guaranteed soak, 3 event outputs and looping.

Programmable Analog Output and Remote Setpoint Input

AUX Pushbutton and LED for front panel switching of:

• PID1/PID2

• Remote/Local Setpoint

• Main/Auxiliary Setpoint

• Ramp/Soak Operation

• Manual/Auto Control

Security Code Protection prevents unauthorized access.

Setpoint Ramp Rate provides Soft Start at powerup, or on setpoint changes, to prevent uneven heating and overshoot.

Control Loop Protection provides process protection from:

• Open Sensor

• Shorted Sensor

• Sensor Reversed

• Control Output Open or Shorted

• Power Control Device Open or Shorted

• Load Power Missing and Self Diagnostics.
