12 V compliance at 20 mA. Output derived from filtered or unfiltered signal input. This option is compatible with all Laureate meters and counters, and turns these into highly accurate, sourcing, 4-wire transmitters. The output for thermocouples, RTDs and custom curves is linearized to the displayed reading. The analog output can track the unfiltered signal for fastest response, or the digitally filtered signal for best noise rejection. Scaling of the output is easily entered via front panel pushbuttons or via the serial digital interface.
Isolation is provided by a separate on-board power supply, which is powered by the meter.
This supply can drive 20 mA current into loads up to 600 ohms, for 12 V compliance. Isolation to signal ground and power ground eliminates problems caused by ground loops. The 0-10 V output capability of the analog output board is ideal to drive a strip chart recorder. The output is linearized to the reading, a major benefit with thermocouple and RTD inputs. The 4-20 mA signal can be transmitted via twisted pair wires to a control room for supervisory process monitoring and control.
