ABB SDCS-IOB-3-COAT 3ADT220090R0020 Analog I/O Board

Frequently Asked Questions (FAQ)

Q1: How many analog channels are available on the SDCS-IOB-3 board?
A1: The board supports 5 analog input channels and 3 analog output channels.

Q2: What are the input voltage and current ranges?
A2: Voltage input range is -10V to +10V; current input range is -20 mA to +20 mA.

Q3: What is the maximum output current?
A3: Each analog output channel supports up to 5 mA.

Q4: Are the encoder inputs isolated?
A4: Yes, encoder inputs are optically isolated and support both differential and single-ended modes.

Q5: How should the board be installed?
A5: It must be mounted outside the DCS module, with conductive supports properly grounded.

Q6: What encoder supply voltages are supported?
A6: 5V, 12V, and 24V; for 5V, it is recommended to use sense lines to compensate for voltage drops.

Q7: Does the board support temperature sensing?
A7: Yes, it supports PTC and PT100 sensors with current sources of 1.5 mA and 5 mA, respectively.

Q8: What is the maximum cable length allowed?
A8: Maximum 1.7 meters between X1 and X2, and 0.5 meters between X1 and X3 due to EMC considerations.
