A18 Series intelligent temperature controller - A18

A18 Series intelligent temperature controller

1. INTRODUCTION.

• A18 series temperature controller is an economical and easy to operate industrial temperature controller. It is designed for various applications, for plastic industries, food processing equipment's, packaging equipments's, environmental test instrument's and general In-process temperature controls (eg. Furnace, Drum heating, Pipe line heating).
• Using Advance artificial intelligence control algorithm with Auto tuning , A18 reduces the "overshoot" problem without the need of going through a complicated PID parameter setting pre-run. A18 can achieve precise controls with minimum set up time.
• The temperature controller has an advanced Modular Output structure allow various outputs options be configured for quick delivery. This also allows easy field service and to implement regular maintenance program ( example, replace a new Relay Module for every 100,000 hours of estimated switching operations)
• It can be operate with universal line voltage, of 100~240VAC 50/60 Hz power supply.

Slots of modules

A-18/A18P series instruments have five slots for modules to be installed (D dimension instruments have 3 slots: OUTP, AUX and COMM/AL1; D2 dimension instruments have 2 slots: OUTP and COMM/AUX). By installing different modules, the controller can meet the requirements of different functions and output types

• Multiple function Input / Output (MIO): Can input signal from 2-wire transmitter or 4-20mA signal by installing I4 (current input) module and I4 module can provide 24VDC to transmitter. If an I2 (on-off signal input) module is installed, the instrument can switch between set points SV1 and SV2 by an external switch. Cooperating with OUTP and installing a K3 module can realize three-phase thyristor zero cross triggering output.
• Main output (OUTP): Commonly used as control output such as on-off control, standard PID control, and HM PID control. It can be used as retransmission output of process value (PV) or set point (SV). Installing L1 or L4 modular can realize relay contact output; installing X3 or X5 module can realize 0-20mA/4-20mA/0-10mA linear current output; installing G module can realize SSR voltage output; installing W1 or W2 module can implement TRIAC no contact switch output.
• Main output (OUTP): Commonly used as control output such as on-off control, standard PID control, and HM PID control. It can be used as retransmission output of process value (PV) or set point (SV). Installing L1 or L4 modular can realize relay contact output; installing X3 or X5 module can realize 0-20mA/4-20mA/0-10mA linear current output; installing G module can realize SSR voltage output; installing W1 or W2 module can implement TRIAC no contact switch output.
• Alarm (ALM): Commonly used as alarm output. Support 1 normally open + normally close relay output (AL1) by installing L1 or L2 module or 2 normally open relay outputs (AL1+AL2) by installing L5 module.
• Auxiliary output (AUX): In a heating/refrigerating dual output system, module X3, X5, L1, L4, G, W1, W2 can be installed for the second control output. It can also output alarm by installing L1, L2 or L5 module, or be used for communicating with computer by installing R module (RS232C interface).
• Communication Interface (COMM): Module S or S4 can be installed in for communicating with computer (RS485 communication interface), and it can also be used as power supply for external sensor when equipped with a voltage output module.

FRONT PANEL AND OPERATION

Basal display status: When power on, the upper display window of the instrument shows the process value (PV), and the lower window shows the set point (SV). This status is called basal display status. When the input signal is out of the measurable range (for example, the thermocouple or RTD circuit is break, or input specification sets wrong), the upper display window will alternately display "orAL" and the high limit or the low limit of PV, and the instrument will automatically stop output
