Design and Isolation Features

This assembly provides true isolation between every I/O point and the bus. Each channel has its own optoisolator with a 2500 VAC rating. Consequently, ground loops and electrical noise will not affect your system. A built-in transient suppressor protects each point from voltage spikes.

Configuration Flexibility

You can configure each of the 16 points as either an input or an output. This flexibility reduces the number of spare modules you need to keep. Moreover, the GE IC660EBS101 supports mixed configurations within the same unit. For instance, you can set 10 points as inputs and 6 points as outputs.

Installation and Connectivity

Two 18-pin removable terminal strips simplify field wiring connections. You can remove these strips without detaching any wires from the panel. The unit mounts directly onto a Genius I/O terminal base. Leave 5 cm clearance above and below the assembly for proper cooling.

Performance Specifications

The assembly updates all 16 points within a 5-millisecond window. This speed works well for discrete control tasks like limit switches or small solenoids. The unit draws only 320 mA from the 24 VDC field supply. A 470 µF capacitor maintains logic power during brief supply dips.

Visual Diagnostics

A row of 16 red LEDs shows the real-time status of each I/O point. An additional green LED indicates that the module has power. Therefore, technicians can troubleshoot issues without opening the cabinet door.

Why Choose This Assembly

This electronic assembly replaces older Genius I/O blocks without changing the base wiring. Its point-level isolation exceeds most competitive products in this class. As a result, you will see fewer noise-related failures in your control system.
