Instant Accuracy Technology Ensures Maxmum       Accuracy in Thermally Unstable Environments

PC or DIP Switch Configuration

Eliminates Ground Loops with 1800V Input-to       Output Isolation

Field Configurable Output; Any Range within       0/20mA or 0/10V

Easy Field Configurable Input Ranges for RTDs,       Thermocouples, Ohms & mV

The ActionI/Q model Q488 is a DIN rail mount, RTD, thermocouple, mV or Ohm input signal conditioner with 1800V isolation between input, output and power. The field configurable input and output offers flexible, wide ranging capability for most temperature signal conditioning applications.

The field configurable input of the Q488 is configured via DIP switch for the thermocouple type (B, C, E, J, K, N, R, S, T) or the RTD type (Pt, Ni & Cu). Additionally, functions such as signal linearization, up or down scale burnout, number (2, 3, 4) of RTD leads and voltage or current output are also set via DIP switches (see Tables 1, 2, 5 & 6).

An optional Microsoft Windows® based (PC) program on CD ROM and serial port adapter cable are available (model C681) for those who would prefer PC configuration capability. The Graphic User Interface (GUI) program takes the place of setting DIP switches and using the push button for ranging. The C681 GUI program can significantly speed configuration and an input signal calibrator is not required for ranging since the values only need to be entered and down loaded.
