Description

The N1500 series of Universal Process Indicators are high performance instruments used for monitoring analogue signals in the vast majority of industrial and laboratory processes.
Configuration from the front panel is fast and easy, accepting thermocouples, PT100 and 4-20mA or voltage signals without any hardware change.
The basic version comes with key panel programmable range, selectable decimal point, universal switching power supply, 24vDC output for field transmitters excitation, ultra bright five digit LED display and 2 relay alarms with 6 function options. 4 to 20mA output for retransmission of measured variable to a recorder or PLC, two extra alarm relays, 1 digital input, RS485 digital communication interface and 10vDC output for load cell excitation are available as options.
The indicator is also available with the option of two further alarm relays and a 4-20mA output (for retransmission of a measured variable to a recorder PLC).
