Sensor/actuator terminal block, nom. voltage: 24 V, nominal current: 18 A, connection method: Spring-cage
connection, number of connections: 4, cross section:0.08 mm² - 4 mm², AWG: 28 - 12, width: 5.2 mm, color:
gray, mounting type: NS 35/7,5, NS 35/15
Your advantages
Three-conductor output terminal block of the same shape with PE connection in the lower level for wiring actuators
Power terminal blocks can be located at any point on the terminal strip for supply or extension purposes
Versions with LED for indicating the switching states
Easy bridging and potential distribution using the patented plug-in bridges from the CLIPLINE complete system
Potential is supplied via the STIO-IN power terminal blocks
For space and time-saving wiring of three-conductor initiators and actuators
The upper level is for signal wiring, whereas the two lower levels are used to distribute the positive and negative potential
