Universal electronic control and monitoring device EXZT/IGZ

For single-line, multi-line and sequential lubrication systems

The IGZ 51 and EXZT universal electronic control and monitoring units are used in multi-line and sequential lubrication systems and are available in two supply voltages. These units are designed for stationary industrial equipment and can be installed in a control cabinet or inside a compact lubrication unit. They can be used as time- or pulse-dependent controllers to initiate the lubrication cycle. EXZT units monitor pump runtime and simultaneously monitor pulses from the pulse generator or metering sensor. All units are equipped with built-in functions tailored to customer requirements and can be configured to meet system requirements.

Technical characteristics and advantages

Combined universal control and monitoring device
Easy installation with U-shaped mounting rail
Adjustable operating modes
Timed response, depending on the load or stroke of the mechanism
The package includes a low level monitor and an EEPROM.

Application areas

Stationary industrial installations
Installation in a distribution cabinet for stationary equipment for general industrial purposes
