I/O modules

The GE D0M202 output module drives actuators from a VersaMax control system. This unit weighs 0.18 kg and measures 9.5 cm x 7.0 cm x 5.5 cm. It provides 2 discrete output channels for field device control. The module contains two power transistors and one logic interface IC. For energy storage, it includes one 47µF electrolytic capacitor. Consequently, the GE D0M202 maintains output states during brief power interruptions.

Technical Specifications

The table below lists all verified parameters for the GE D0M202. Use this data for your system integration planning.

Output Channel Features

Each of the 2 output channels uses a separate power transistor with protection. The GE D0M202 provides sourcing outputs at 24V DC operation. Therefore, you can drive solenoids, contactors, and indicator lamps directly. Each channel delivers 2.0 A continuously without overheating. For short circuits, the module includes self-resetting protection on every channel.

Switching Performance

The turn-on time reaches just 0.5 milliseconds for fast response. The turn-off time stays under 1.0 millisecond for reliable control. Thus, this output module suits high-speed automation sequences effectively. The inrush current capability reaches 5.0 A for 20 milliseconds. Therefore, the GE D0M202 handles lamp loads and capacitive devices reliably.

Protection Features

This output module includes short circuit protection that resets automatically. After removing the fault, the channel restores normal operation. Additionally, thermal overload protection prevents damage from prolonged overcurrent. Hence, the GE D0M202 survives harsh field conditions without failure. The logic interface IC isolates the field outputs from the backplane.

Power and Energy Storage

The GE D0M202 draws 30 mA from the 5V DC backplane supply. Additionally, it requires 24V DC field power for the outputs. Hence, the logic power consumption equals just 0.15W. The 47µF electrolytic capacitor provides 5 milliseconds of hold-up time. This short backup protects output states during minor voltage sags. Furthermore, the module includes reverse polarity protection on its field power input.

Installation and Wiring

You can mount the GE D0M202 on a standard DIN rail. The module snaps directly into any VersaMax I/O carrier. The 5-pin terminal block accepts wire sizes from 0.2 mm² to 2.5 mm². For inductive loads, install external flyback diodes across each device. The GE D0M202 works seamlessly with the RMS-TSG-TZ-C static trip unit.

Environmental Durability

This output module operates reliably from -10°C to +55°C. It also withstands 90% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the GE D0M202 suits most compact automation systems perfectly.
