The T723 offers a choice of J/K/T or E/R/S input ranges and 2 output ranges, which are field selectable via top-accessed DIP switches (see Tables 1-2). The T723 provides 600 VDC input to output of isolation with outputs of either 4-20mA or 10-50mA. The current output is linear to the equivalent mV thermocouple signal and non-linear to temperature. This is useful in data acquisition systems that utilize linearizing software. Upscale burnout is standard. This provides a maximum output with an open thermocouple.

A major advantage of the T723 is its wide ranging capability. The T723 enables 80% zero and span adjustability within any user selected input ranges shown in Table 1 and 2. For example, Range K1 of Table 1 specifies 0 to 500 C with a minimum span of 100 (500-100 = 400, or 80%). This 80% adjustability factor allows the user to field calibrate the unit for the maximum (0 to 500) down to any minimum (100C) span (e.g. 14C to 114C)--as long as that adjusted span remains within the selected 0 to 500C range. The same is true for any adjustable span, minimum or otherwise, in any user selectable range: all spans are field adjustable from 20% (minimum span) to 100% of the specified range.
