Installation Guide

1. Install the BMXDDO1602 into a standard I/O slot on the Modicon X80 backplane (M340 or M580 rack).
2. Connect the 20-way removable terminal block to the module front.
3. Wire 16 output channels to field devices (actuators, solenoids, relays) observing positive logic polarity.
4. Connect 24 VDC power to the module via the terminal block.
5. Install 2 A external fuses per channel if required by your application.
6. Ensure load impedance > 48 Ω per channel.
7. Power on and verify RUN LED (green) illuminates; check per-channel green LEDs for active outputs.
8. Monitor ERR LED (red) for overload, short-circuit, or module fault conditions.

FAQ

Q: Is BMXDDO1602 relay or transistor output?
A: Transistor (solid-state) output. Some third-party sources incorrectly describe it as relay output. The BMXDDO1602 uses transistor technology for fast switching and high reliability. For relay outputs, use BMXDRA1605 or BMXDRC0805.

Q: Is BMXDDO1602 source or sink type?
A: Source type (positive logic). The module sources current to the load when the output is energized. For sink type (negative logic), use BMXDDO1602H or other sink variants.

Q: What is the difference between BMXDDO1602 and BMXDDO1602H?
A: BMXDDO1602 is the standard version. BMXDDO1602H is the conformal coated version for harsh environments (moisture/salt spray/mildew resistant). Both have identical electrical specifications.

Q: What is the difference between BMXDDO1602 and BMXDDO1612?
A: BMXDDO1602 has 0.5 A per channel (10 A module max). BMXDDO1612 has 0.1 A per channel (1.6 A module max) with faster 0.1 ms response time for high-speed applications.

Q: Can I parallel outputs for higher current?
A: Yes, up to 2 channels maximum. Paralleling two channels provides up to 1 A combined current. Do not exceed module maximum of 10 A.

Q: Is BMXDDO1602 compatible with M580?
A: Yes. The BMXDDO1602 is part of the Modicon X80 platform and is compatible with both M340 PAC and M580 ePAC systems using the X80 backplane.

Q: What is the maximum inrush current?
A: The module supports electronic overload protection with current limiting at 1.5× to 2× rated current (0.75–1 A per channel). For higher inrush loads, consider relay output modules.
