FAQ for HIMAX X-DI3201

• Q1: How does line control work with the DI 32 01?

A: Line control detects short-circuits and open-circuits on safety inputs (e.g., emergency stop circuits per Cat. 4):
Connect pulsed outputs (DO 1...DO 8) from a DIO 24/16 01 module to DI 32 01 inputs
Configure DI Number of Pulsed Outputs (0-8) and DI Pulse Slot (1-6) in SILworX/ELOP II Factory
Configure DI Pulse Delay (waiting time for line control detection)
Configure DI[xx].Pulsed Channel to assign which DO channel pulses each input

• Q2: What is the switching point for the digital inputs?

A: Typical switching point is 7.5 V.
Input voltage > 7.5 V → High level (energized) → LED ON
Input voltage < 7.5 V → Low level (de-energized) → LED OFF
High level range: 10...30 VDC
Low level range: ≤ 5 VDC (max.)

• Q3:  Can I use external power supplies for the inputs?

A: The module provides short-circuit-proof supplies (LS+) for each input group:
LS+ provides 20 V / 100 mA at 24 V per group
Each group (7 inputs except last group of 4) shares one LS+
