Otek's ANSI 4-inch digital panel meter, the NTM-N, is a form, fit and function replacement for analog meters such as the GE/Yokogawa DB40, Weschler/Westinghouse k231/k241, Dixson BEW51 and Crompton 077. A single channel bar-digital meter, the NTM-N is available in loop power (at 4-20mA), A.C. signal power, or external power options. Externally powered, the NTM-N can accommodate 4 relays, isolated DAC, over 30 signal conditioners and isolated input power, as well as ethernet. Powered by the loop or signal, the NTM-N offers isolated serial I/O options in USB or RS485. The NTM-N carries a 4-digit ultra-bright LED display with an automatic tricolor bar that includes intensity control. Features include an input fail alarm with runtime stamp, self-diagnostics, a configurable bar direction with commands for up/down/center zero, math functions, a 4-20mA/30V output and power requirements of only 100mW@5VDC.
