ABB 200C-OB16P – Digital Output Module for High-Speed Switching

The ABB 200C-OB16P drives solenoids, relays, and indicator lamps in control systems. This module measures 120 mm in width and 100 mm in height. It has a depth of 65 mm, so it fits standard DIN rail enclosures. The unit weighs 0.35 kg, making installation quick and effortless.

Internal Architecture and Channel Configuration

This digital output module contains two separate circuit boards inside its plastic housing. One board handles logic interfacing, while the other manages output switching and protection. The ABB 200C-OB16P includes sixteen sourcing output channels on its front panel. Each channel uses a power MOSFET rated for 0.5 amps continuous. The module stores 100 µF of capacitance for output filtering only.

Output Specifications and Field Wiring

You can connect each output channel to loads from 5V DC up to 30V DC. The ABB 200C-OB16P provides a total current rating of 8 amps across all channels. Each output channel includes short-circuit protection with automatic shutdown. The module offers eighteen screw terminals for field wiring connections. These terminals accept wire gauges from 24 AWG to 16 AWG comfortably.

Power Requirements and Communication Interface

You must supply 24V DC logic power to the dedicated terminals on this module. The ABB 200C-OB16P draws 45 mA at 24V DC for internal logic operation. A 20-pin ribbon cable carries output data from the main controller. The module updates all sixteen channels every 1 millisecond. For surge protection, each output includes a flyback diode for inductive loads.

Output Response and Environmental Tolerance

The module turns outputs on within 50 microseconds of receiving a command. The ABB 200C-OB16P turns outputs off within 30 microseconds for fast response. LED indicators on the front panel show each channel’s current on/off status clearly. The device operates reliably from 0°C to 55°C ambient temperature. It tolerates humidity levels up to 90 percent without any condensation issues.

Below is a complete summary of its technical specifications.

The ABB 200C-OB16P replaces older digital output cards in AC500 systems directly. You do not need any special adapters or additional configuration software. This module also protects each channel with thermal shutdown for safety. Therefore, it suits solenoid control and relay actuation in factory automation.
