KL1859 | Bus Terminal, 8-channel digital input + 8-channel digital output, 24 V DC, 3 ms, 0.5 A
The KL1859 digital input terminal combines eight digital inputs and eight digital outputs in one device. The signal state of the channels is indicated by LEDs. The reference ground for all inputs is the 0 V DC power contact; the outputs are fed via the 24 V power contact.
Special features:
- compact design through the combination of inputs and outputs in one terminal
- no bouncing due to mechanical switches thanks to 3 ms input filter
- short-circuit proof outputs protected against reverse polarity with output current up to 0.5 A
- tool-free connection by direct plug-in technology for solid wire conductors
- increased packing density with 16 connection points in the housing of a 12 mm terminal block
