● Each output is rated for 0.5 A current and is electronically protected.
● 4 digital outputs can be operated simultaneously each with up to 0.5 A (up to 1.0 A in
total).
● The outputs are optically isolated through optocouplers.
Input Inport (0), (1), (2), (3)
● The inputs are optically isolated through optocouplers.
● Level Low 0 ... 3 V; High 3.6 ... 24 V
● Sampling rate < 20 ms
