The workhorse. Full 3.0 A per motor for torque to start heavier product and more usable speed under load — where most two-zone cards cap at 2.5 A.
The density play. At 2.0 A per motor, more modules chain from a single supply — for lighter loads and longer runs of zones per drop.
See the power architecture below for how far each model reaches from one supply.
Both models share the field interface, enclosure, and mounting — so a line can mix them freely.
High voltage travels to a conveyor-mounted supply box; only short 24 V cordsets leave it, chaining module to module. Both models share the same supply, connectors, and cabling — the lower-current model simply reaches further.
At 24 V, voltage drop — not current — caps cable length. High voltage runs the distance to a conveyor-mounted box; only short 24 V cordsets leave it.
The power cordset gangs three pins per rail at ~6 A each. Three MDX230 modules draw ~18 A across the 20 A circuit and series-chain straight through — no separate power trunk.
Same 20 A circuit, same connectors: MDX230 runs three modules, and the lighter 4 A MDX220 reaches four — so a denser line needs no different power hardware.
// Recommended continuous loading per 20 A circuit: MDX230 three modules (18 A), MDX220 four (16 A); two circuits per supply box. Connector/wire ceiling is higher but not advised for continuous conveyor duty.
