ABB 07 YS 81: High-Density Binary Output Module for Procontic

The ABB 07 YS 81 delivers sixteen binary output channels in a compact form. This module drives solenoids, contactors, and indicator lights directly. You can mount it inside any Procontic controller rack seamlessly. Its transistor-based design ensures fast switching without mechanical wear.

Technical Specifications and Hardware Architecture

This binary output module measures 130 mm in height. Its width reaches 55 mm, and the depth equals 110 mm. The ABB 07 YS 81 weighs approximately 0.4 kilograms. Sixteen discrete transistor outputs populate the single internal PCB. Each output uses a MOSFET for silent and rapid operation. The module stores no energy in capacitors or batteries. Instead, it draws all necessary power from the backplane bus. One 40-pin front connector handles all field wiring tasks. A red LED per channel indicates the active output state.

Electrical Ratings and Switching Performance

Each output on the ABB 07 YS 81 handles 0.5 A at 24 V DC. The total current per common group reaches 4 A maximum. Switching frequency goes up to 1 kHz for fast sequencing tasks. Therefore, this module suits PWM control or high-speed counting applications. The module provides short-circuit protection on every channel. Additionally, optical isolation separates the field side from the backplane logic.

Installation and Practical Wiring Guidelines

You must insert this module into a standard Procontic backplane slot. Transitioning to wiring, use solid or stranded copper wires of 0.5 mm². The screwless spring terminals allow tool-free wire insertion. For inductive loads, always connect a freewheeling diode across each output. This precaution prevents voltage spikes from damaging the MOSFETs. The module operates reliably between 0°C and 60°C ambient.
