Description

The GE IC693ALG390 is part of the Series 90-30 family of programmable logic controller (PLC) modules. It serves as an analog voltage output module, offering two channels capable of providing voltage output in the range of -10V to +10V DC. Each channel delivers a resolution of 2.5 mV (1 LSB = 2.5 mV) and offers absolute accuracy of ± 5 mV at 25°C (77°F). With an offset of 1 mV maximum over a temperature range of 0 to 60°C (32°F to 140°F), the module ensures precise control and measurement.

The IC693ALG390 provides an update rate of 5 ms for both channels, which depends on the I/O scan time and the user program’s structure. This ensures that control signals are updated quickly and accurately, making the module ideal for closed-loop control systems, data logging, and other industrial applications.

Power and Supply Requirements

To operate the IC693ALG390, an external supply voltage between 18V and 30V DC is required. The module is designed to accept a nominal supply voltage of 24V DC, either from an isolated +24V DC backplane or a user-supplied voltage source. Additionally, the module requires +5V DC from the backplane and can tolerate a voltage ripple of up to 10%.

Isolation and Safety

The IC693ALG390 ensures safe operation with 1500 V RMS isolation between the field side and the logic side. This isolation enhances reliability by preventing electrical interference and protecting both the module and connected equipment from voltage spikes.

Configuration and Operation

This module allows for easy configuration via the DEF0 jumper on the removable terminal block. When the CPU switches to STOP or RESET mode, the module can be set to either hold the last-state output or provide a 0V output. By default, it holds the last output state.
