Features
Control Types - Full PID with Pre-tune, Self-tune, Manual Tuning, or On-Off control. Heat only or heat & cool. Auto/Manual - Selectable from front panel or external selection via digital input, with bumpless transfer. Output Configuration - Up to 3 possible, for control (Heat & Cool), Alarm or retransmit of Process Value or Setpoint. Alarm 1 & 2 Types - Process high, process low, SP deviation, band, logical OR with adjustable hysteresis. Also 1 loop alarm for process security. Human Interface - 4 button operation, dual 4 digit 10mm & 8mm high LED displays with choice of Red/Green (standard) and Red/Red or Green/Green plus 5 LED indicators. Manual or PC Configuration - Off-line configuration from serial port to dedicated config socket (comms option not required).
Input
Thermocouple - J, K, C, R, S, T, B, L, N & PtRh20%vsPtRh40%. Scalable within selected range. RTD - 3 Wire PT100, 50ohm per lead maximum (balanced). Scalable within selected range. DC Linear - 0-20/4-20mA, 0-50/10-50mV, 0-5/1-5/0-10/2-10V. Scaleable -1999 to 9999, decimal point selectable. Impedance - >10Mohm for Thermocouple and mV ranges, 47Kohm for V ranges and 5ohm for mA ranges. Accuracy - +/- 0.1% of input range +/- 1 LSD (T/C CJC better than 1°C). Sampling - 4 per second, 14 bit resolution approximately. Sensor Break Detection - <2 secs (except zero based DC ranges), control O/P's turn off, high alarms activate for T/C and mV ranges, low alarms activate for RTD, mA or V ranges.
