OTEK's new system panel meter, model SPM, now offers a variety of plug-in options, such as signal conditions for Strain-Gage, RTD, TC, pH, ORP, %RH, flow, events, V/mADC and RMS. The SPM is Powerless™ for 4-20mA, VDC, mADC, VAC, AAC, Hz and watts inputs. For AC, V, A, W and Hz, the SPM is powered from existing P.T and/or C.T. to display their values. For 4-20mA or V/mADC inputs, the SPM "steals" the under 100mW required to power the electronics and high efficiency display (LED or backlit LCD). If the signal cannot spare the under 100mW of energy, users can externally power the SPM with 5-48 vDC or 90-265 vAC and get relays, O.C.T., serial I/O, math functions, analog out, or other functions as long as they fit in the 1/8 DIN case.
