Key Features
- Digital input channels: 16 digital inputs in groups of 1; above +60 °C, a maximum of 4 non-adjacent inputs can be controlled simultaneously.
- Input voltage: Rated input values are 24 V, 48 V and 125 V DC, or 24 V, 48 V and 125 V AC at 50 – 60 Hz.
- Signal ranges: Signal 0: -5 … +5 V. Signal 1: +11 … +146 V; typical current is 3 mA at 24 V DC.
- Input delay: Parameterizable DC input delay: 0.05 / 0.1 / 0.4 / 1.6 / 3.2 / 12.8 / 20 ms; AC input delay is fixed at 20 ms.
- Diagnostics and interrupts: The module has diagnostics, diagnostic alarms, hardware interrupts, wire-break detection to I < 550 μA, and green or red diagnostic LEDs.
- Electrical isolation: Channels are electrically isolated from one another in groups of 1 and isolated from the backplane bus; permissible difference between different circuits is 146 V DC/132 V AC.
