General  Description

This series of meters accepts industrial sensors to allow various physical measurements to
be made, such a weight, temperature, pressure, humidity etc. Different models are available
for different sensor types.

The main function of this series is to give a numeric readout of the variable being monitored.
Most models include an excitation power output, to power the sensor directly.

Various optional output modules are also available to give alarm relay outputs, analogue
output or digital communications, or any combination of these options.

Meters are programmed using front panel pushbuttons. The buttons may be locked with a
rear switch.

Meters have two power supply options : 100-240 VAC or 11-30VDC

These meters are designed to mount into a protective enclosure which will protect users from
contact with power and signal wiring.

These units must be installed fully assembled, and must be installed according to local electrical
installation rules. When properly installed, they provide ingress protection to IP65 / NMA4X
from the front

Safety

Obey all safety warnings in this manual, and install the meter according to local wiring and
installation regulations. Failure to follow these guidelines may cause damage to the meter,
connected equipment, or may be harmful to personnel.

Any moving mechanical device controlled by this equipment must have suitable access guards
to prevent injury to personnel if the meter should fail.
