ABB 07 YS 86: Durable Relay Output Module for Procontic Systems

The ABB 07 YS 86 provides eight independent relay output channels. This module switches resistive or inductive loads with complete electrical isolation. You can integrate it directly into Procontic controller racks. Its design suits motor starters, solenoid valves, and indicator lamps.

Technical Specifications and Component Layout

This output module measures 130 mm in height. Its width reaches 45 mm, while the depth extends to 110 mm. The ABB 07 YS 86 weighs approximately 0.35 kilograms. Eight electro-mechanical relays populate the main PCB. Each relay includes a silver-cadmium oxide contact for extended life. The module stores no energy in capacitors or batteries. Instead, it relies on the backplane for all operating power. One 20-pin front connector handles all field wiring. A separate green LED per channel shows the energized status.

Electrical Ratings and Switching Capacity

Each relay on the ABB 07 YS 86 handles 2 A at 250 V AC. For DC loads, the rating reaches 2 A at 30 V DC. The module can switch up to 30 operations per minute. Consequently, this speed works for most industrial sequencing tasks. The minimum switching load sits at 10 mA or 5 V. Additionally, the module provides 4 kV of isolation between channels and logic.

Installation and Practical Wiring Advice

You must seat this module firmly into a Procontic backplane slot. Transitioning to field wiring, use stranded copper wire between 0.5 mm² and 2.5 mm². The module’s screw terminals accept stripped wire ends directly. For inductive loads, always attach a suppression diode or RC snubber. This practice prevents contact welding and extends relay life significantly.
