Programmable meters with bargraph with RS-485 interface, analog and relays outputs - NA22 |
|
|
Programmable meters with bargraph indicators NA22 types are destined to measure a.c. current, a.c. voltage, temperature, resistance and other non-electrical magnitudes like level, flow, pressure, humidity converted into an electrical signal.
-
input: programmable
- voltage 0...300 mV, 0...200V, - 5...60V,
- current 0...200 mA, 0...2A,
- temperature: thermocouples, resistance thermometers,
- 0...400W
- output: programmable - relay, analog, digital RS-485 with MODBUS protocol,
- display field:
- NA22 type - 2 displays with 3 LED digits 7,6mm high,
2 bargraphs 92mm high, 2 measuring channels.
- supply: 95...230...253 V a.c./d.c., 20...24...40 V a.c./d.c.
Next to programmable measuring functions meters have many additional functions:
- signalling of alarm states,
- re-count of the input signal into indication based on individual linear characteristic,
- programmable bargraph resolution,
- programmable continuous output,
- programmable indication value,
- supply of object transducers,
- RS-485 digital output with MODBUS (ASCII or RTU) transmission protocol,
- galvanic isolation,
- fixing in the panel.
External dimensions:
- 36 x 144 x 130mm (NA21 and NA22 type)
