Schneider BMXDDO1602 Discrete Output Module

Frequently Asked Questions (FAQ)

Q1: Can BMXDDO1602 directly drive relays?
A1: Yes, it can drive small DC relays, provided the coil current does not exceed 0.5 A per channel.

Q2: Does the module support output channel paralleling?
A2: Yes, two channels can be paralleled, but ensure the total current stays within the module’s rated maximum.

Q3: Is short-circuit protection built into the module?
A3: No, external 2 A fuses are required for each output channel to protect against short circuits.

Q4: How can I check the module status?
A4: Status can be verified via LEDs on the module—RUN, channel diagnosis, module error, and I/O fault indicators.

Q5: Are there altitude limitations for operation?
A5: Yes, operation above 2000 m requires load derating according to the manufacturer’s specification.

Q6: What is the response time of the module?
A6: The output response time is 1.2 ms, suitable for moderate-speed automation tasks.

Q7: Does it include reverse polarity protection?
A7: Yes, the module has a built-in reverse diode to protect against incorrect wiring.

Q8: Are there restrictions on load type?
A8: Yes, the module is intended for resistive loads only, and load impedance must be greater than 48 Ω.
