ABB 07 YS 03B-E Digital Output Module

The 07 YS 03B-E drives 32 digital output channels for Procontic systems. This module switches 24V DC loads like solenoids and indicator lamps. It includes short-circuit protection on each output channel.

Key Technical Specifications

Physical Dimensions and Component Layout

This module measures 16.0 cm in length and 9.0 cm in width. Its total height reaches 5.5 cm including the terminal block. 07 YS 03B-E weighs 0.32 kg for DIN rail mounting. You will find 148 discrete components on a six-layer PCB.

Furthermore, each output channel includes a dedicated protection circuit. This circuit limits current during short-circuit conditions. The module automatically restores operation after fault removal.

Output Channel Design and Characteristics

Each of the 32 channels uses a power MOSFET for switching. The transistor sources 24V DC to the field load. Each channel delivers up to 0.5 A continuously without overheating. Consequently, you can directly drive small solenoids, lamps, and relays.

Protection Features and Diagnostics

Short-circuit protection activates when the output exceeds 0.7 A. Thermal protection shuts down an overheated channel automatically. An LED indicator shows fault status for each individual output. The CPU receives a group fault signal for centralized alarming.

Connector Interface and Field Wiring

A 40-pin screw terminal block accepts field wiring for all 32 outputs. Eight additional terminals provide four separate 24V DC supply connections. Each terminal accepts wire sizes from 26 AWG to 14 AWG. LED indicators sit above each channel for visual status monitoring.

Typical Application Scenarios

You can deploy 07 YS 03B-E in ABB Procontic racks for high-density industrial control. It also works well for controlling actuators, pilot lights, and alarm horns. This module switches small valves, contactor coils, and indicator lamps. Its 32 channels suit medium to large automation tasks.
