MeloAuto-Trusted PLC & DCS Parts Supplier
The GE IC660TBA025 converts digital signals into precise analog outputs for field devices. You can mount this block on a DIN rail or panel in Genius I/O networks. It provides four analog output channels for controlling valves, drives, and actuators. This unit suits process control and continuous manufacturing applications.
Technical Specifications and Hardware Layout
This analog output block measures 210 mm in height. Its width reaches 160 mm, and the depth equals 55 mm. The GE IC660TBA025 weighs approximately 0.95 kilograms. A single internal PCB holds all signal conversion and isolation circuits. The block contains no energy storage capacitors or batteries. One 20-pin removable terminal block handles all field wiring connections. Two 9-pin D-sub connectors provide the Genius bus interface. Four green LEDs display the output status for each channel.

Output Specifications and Electrical Performance
The GE IC660TBA025 delivers 4 to 20 mA outputs for each channel. It drives loop-powered devices up to 750 ohms load resistance. The module provides a 12-bit digital resolution for smooth analog control. Accuracy stays within 0.2 percent of full scale at 25°C. Consequently, this block controls valves and drives with excellent precision. Each channel includes short-circuit protection and open-loop detection. The block requires an external 24 V DC power supply for operation. Genius bus communication uses a redundant configuration for high reliability.
Installation and Communication Guidelines
You must mount this block on a DIN rail using the integral clips. Transitioning to wiring, use twisted-pair shielded cables for analog outputs. The block supports Genius bus baud rates of 153.6 kbit/s. Two rotary switches set the block address from 0 to 31 easily. Four front LEDs show power, bus activity, and channel faults. The operating temperature range spans from -20°C to +60°C reliably.
