N1040i

Description

The N1040i Universal Indicator N1040i combines high precision microprocessor based analogue circuitry with a simple configuration interface capably of monitoring all standard analogue process variables in one compact and convenient 1/16 DIN enclosure.

This low cost, rugged yet versatile indicator accepts all common thermocouple, Pt100 RTD and linear 4 to 20 mA and mV inputs, easily user programable using the intuitive interface to select the sensor type, range and decimal point using just the keypad, as well as all the other internal parameters. The N1040i therefore allows electricians with limited instrumentation knowledge easy installation and start up in most applications.

The N1040i has various build options available giving relay, retransmission, comms and 24Vdc transmitter power supply outputs. The alarms have 6 programmable functions to select from.
