Combined active and passive integrators

SENSOR-actuator integrators with bus systems combine two fundamental concepts: on the spot assembly and pluggable connection technology with efficient wiring of the bus.

However, the bus station itself is the weak link in some applications, and frequently proves just as difficult to wire. Thus, I/O modules react vulnerably to vibrations and impacts.

Furthermore, it is not always possible to unite two sensors in one module position. Bus cables are also less drag-chain suitable than conventional cables.

Weidmuller solves the problems described above by combining active and passive SAI modules into the SAI-Combi - this module proving to be a convincing addition to Weidmuller's SAI family.

There is a base module with two 12-pole M16 plug-in connectors or a module with four 8-pole M12 plug-in connectors available. Active, pluggable modules are available in different variants for DeviceNet or Interbus.

SAI integrators are available in protection class versions IP67 or IP68 and as such do not require a protective enclosure.
