ABB 200-OB16 Digital Output Module

This digital output module drives actuators and indicators from ABB PLC systems. It provides 16 independent channels for controlling solenoids, contactors, and lamps. Therefore, this component suits factory automation and process control applications.

Physical Dimensions and Weight Specifications

The ABB 200-OB16 features a compact housing for DIN rail mounting. Its width measures 56 mm for standard industrial enclosures. The total depth reaches 73 mm including the terminal block. Consequently, technicians can install this module in crowded control cabinets.

Interface Types and Connection Layout

The ABB 200-OB16 provides spring-clamp terminals for field device wiring. A 10-pin backplane connector supplies power and data from the CPU. The front panel carries 16 green LED indicators for output status. Hence, operators can monitor all channels at a quick glance.

Component Count and Channel Configuration

This digital output module contains one main board with 16 MOSFET output channels. Each channel provides 0.5A continuous current at 24V DC. You will also find optocoupler isolation between the backplane and field side. An onboard serial-to-parallel converter reduces backplane pin count.

Energy Storage and Power Consumption

The ABB 200-OB16 draws 80 mA from the 5V backplane supply. It requires an external 24V supply for output load power. A small capacitor bank absorbs voltage spikes from inductive loads. This storage protects the MOSFETs during solenoid switching events.

Output Performance and Diagnostic Features

The module updates all 16 outputs within a 0.5 ms cycle time. Each channel includes short-circuit detection with automatic shutdown. Users can read diagnostic status via the PLC bus system. This feature reduces downtime during field wiring faults.
