• Temperature display
• Frequency display / tachometer
A variety of temperature or frequency signals can be processed.
On the output side, optional analogue signals are available, as
well as either two or four relay contacts for alarm monitoring.
The PMX400 HZX frequency display module offers, as default,
two open-collector outputs as the relay contacts. The outputs
are designated for the alarm function. An integrated power
supply can be used for supplying external sensors and input
devices.
