GE IC670ALG320A Analog Output Module

The GE IC670ALG320A converts digital commands into continuous analog signals for field devices. This analog output module measures 130 mm in height and 45 mm in width. It has a depth of 85 mm, so it fits standard DIN rails easily. The unit weighs 0.26 kg, making installation quick and effortless.

Output Channels and Signal Ranges

This analog output module provides 4 independent output channels on its front panel. The GE IC670ALG320A delivers voltage outputs from 0 to 10V DC. It also provides current outputs from 4 to 20 mA for loop-powered devices. Each channel includes a dedicated 12-bit digital-to-analog converter for precision. You can configure each channel individually for voltage or current mode.

Conversion Accuracy and Response Time

The GE IC670ALG320A achieves a conversion accuracy of ±0.1 percent of full scale. It updates all four outputs within 15 milliseconds for smooth control. The settling time for a full-scale step change reaches 5 milliseconds. Each output channel can drive loads up to 500 ohms in current mode. Voltage outputs drive loads down to 2,000 ohms minimum resistance.

Internal Architecture and Component Layout

The module contains two separate circuit boards inside its plastic housing. One board handles digital-to-analog conversion, while the other manages fieldbus communication. The GE IC670ALG320A includes a dedicated microcontroller for output scaling. A 10-pin removable terminal block accepts all field wiring connections. The module stores 100 µF of capacitance for power supply filtering only.

Network Interface and Power Requirements

A Genius fieldbus interface connects this module to the I/O network. The GE IC670ALG320A draws 200 mA at 24V DC from an external supply. It automatically reports its configuration to the bus controller unit. The module supports hot-swapping for maintenance without system shutdown. Rotary switches set the device address from 0 to 31 easily.
