Product Overview
The Omron DRT2-OD32ML is a Smart Slave 32-point NPN transistor output terminal for DeviceNet It is manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports. It delivers 32 NPN outputs at 0.3 A per point and 4 A per common from a 24 VDC I/O supply, with 0.5 ms ON delay and 1.5 ms OFF delay. Residual voltage is 1.2 V max between each output and G; leakage is 0.1 mA max. For 16 outputs on screw terminals pick the DRT2-OD16-1. Key specs: I/O Configuration 32 outputs, NPN transistor (sinking), one common; Output Rating 0.3 A per point, 4 A per common, residual voltage 1.2 V max, leakage 0.1 mA max; I/O Supply Voltage 24 VDC nominal (20.4 to 26.4 VDC); MIL connector for the 32 outputs; Comm Power 11 to 25 VDC supplied from the DeviceNet communications connector; 70 mA max at 24 VDC; Response Time 0.5 ms ON delay, 1.5 ms OFF delay; Network Protocols DeviceNet slave; supports automatic baud rate detection (125 / 250 / 500 kbps); Smart Features Sensor disconnection detection.
Key Features

Best-Fit Applications
- Solenoid bank control on a 32-station rotary indexing table where the DRT2-OD32ML outputs drive 24 VDC valves through the MIL connector
- Indicator and stack-light cluster on a packaging line where the DRT2-OD32ML drives 32 LED drivers from one DeviceNet drop instead of running home-run cables
- Spare replacement on a bottling line where the original DRT2-OD16-1 panel-mount block is upgraded to the MIL-connector DRT2-OD32ML to halve the DeviceNet node count
Buying Checklist
- Pick the DRT2-OD32ML for 32 NPN outputs on a single DeviceNet node with MIL connector and IP67 smart-slave diagnostics.
- Pick the DRT2-OD32ML-1 instead when the cabinet needs 32 PNP sourcing outputs on the same MIL connector and IP67 body.
- Pick the DRT2-OD16-1 instead when the panel only needs 16 PNP outputs on screw terminals at a lower cost per point.

FAQ for DRT2-OD32ML
What is the Omron DRT2-OD32ML used for?
It is a DRT2-Series Smart Slave remote I/O terminal that delivers 32 NPN transistor outputs to a DeviceNet master. Each point sinks up to 0.3 A from a 24 VDC load and the common carries 4 A. The MIL connector on the front carries the 32 outputs on one ribbon cable, and the IP67 housing tolerates oil and water spray. Typical uses are solenoid banks on rotary indexers, indicator clusters on packaging lines, and any place where running 32 home-run wires would be too expensive.
DRT2-OD32ML vs DRT2-OD32ML-1 - what is the difference?
Both share the 32-point MIL connector body, IP67 housing, and same smart-slave feature set. The DRT2-OD32ML is NPN sinking (switches the load to 0 V); the DRT2-OD32ML-1 is PNP sourcing (switches the load to +24 V). Pick the NPN version for legacy Japanese wiring that switches ground; pick the -1 for European panels that switch +24 V.
What cable connects to the DRT2-OD32ML MIL output?
A standard 40-pin MIL flat-cable harness with 32 outputs plus grounds and commons. The MIL cable is sold separately from the DRT2-OD32ML. Omron offers pre-wired MIL-to-Phoenix breakout cables (XW2Z series) for panel wiring. Maximum recommended cable length is 3 m to keep the MIL-connector signal integrity.
Does the DRT2-OD32ML need an external 24 VDC supply?
Yes, for the I/O outputs. The DeviceNet trunk supplies the 11 to 25 VDC communications power from the bus, but the 24 VDC that feeds the output loads must come from an external 24 VDC source landed on the I/O power terminals. The DRT2-OD32ML passes that supply through to the output commons.
