The instrument accepts four analog signals of either DC or AC Voltage, DC or AC Current, RTD Pt-100 or Thermocouple Sensors and simultaneously displays all four parameters on a 4-line x 20-character bright OLED display. The instrument offers four configurable control Relay outputs – one per channel. The instrument also offers four analog retransmission signals – one per channel. The complete data of all four channels may be communicated on RS485 port on Modbus RTU or TCP/IP protocol. The instrument operates on universal AC power supply of 90 to 270 VAC, 50/60 Hz.
