Modicon X80 Relay Output Characteristics

The BMXDRA1605H provides 16 relay-based discrete output channels with positive output logic. The relay contacts support field circuits from 19 to 264 VAC and 19 to 30 VDC within the specified nominal ranges. The minimum switching current is 1 mA at 5 VDC. Output response is specified at less than 8 ms for activation and less than 10 ms for deactivation.

The module operates from the Modicon X80 common I/O platform used with Modicon M580 and M340 Programmable Automation Controllers. Its conformal coating and stated environmental classifications support installation in severe environmental conditions. The module has an IP20 enclosure rating and requires appropriate cabinet-level protection against direct exposure to liquids and conductive contamination.

Q: What is the specified output response time?

A: Output activation is specified at less than 8 ms, while output deactivation is specified at less than 10 ms.

Field Installation Guidelines

Install the BMXDRA1605H in the appropriate Modicon X80 rack and verify that the module position and terminal arrangement correspond to the system configuration.

Before wiring, isolate field power and verify the intended AC or DC circuit voltage. Select conductors and external protection according to the connected load and applicable electrical installation requirements.

Keep relay output wiring separated from low-level analog, communication, and sensitive signal wiring where practical. Route high-current or inductive load conductors separately from signal circuits to reduce conducted and radiated interference.

Terminate cable shields according to the plant grounding design. Do not use the module enclosure or signal wiring as an uncontrolled protective-earth path.

Because the module is IP20 rated, install it inside an enclosure providing the required environmental and electrical protection. Verify temperature, humidity, contamination, and mechanical conditions against the specified installation environment before energizing the rack.
