Analog Input Features
The GE IC694ALG442 offers 4 analog input channels with 16-bit resolution. You can configure each input for voltage or current independently. Therefore, you can connect various sensor types to this single module. The input impedance sits at 1 MΩ for voltage mode and 250 Ω for current mode. Consequently, the module does not load down sensitive signal sources.
Analog Output Features
This combination module provides 2 analog output channels with 12-bit resolution. You can select either voltage or current mode for each output. Hence, the GE IC694ALG442 drives both voltage-controlled and current-controlled actuators. The output settling time reaches just 5 milliseconds for full-scale changes. Thus, this module suits closed-loop control applications effectively.
Power and Energy Storage
The GE IC694ALG442 draws 150 mA from a 5V DC logic supply. Additionally, it requires 24V DC at 50 mA for field power. Hence, the total power consumption equals 1.95W. The two 100µF tantalum capacitors provide 10 milliseconds of hold-up time. This short backup protects signal values during minor voltage sags. Furthermore, the module includes reverse polarity protection on its field power input.
Installation and Wiring
You can mount the GE IC694ALG442 on a standard DIN rail. The module snaps directly into any RX3i I/O slot. The 20-pin removable terminal block accepts wire sizes from 0.2 mm² to 2.5 mm². For voltage signals, use twisted-pair cables with one wire grounded. For current loops, a simple two-wire cable works perfectly. The GE IC694ALG442 works seamlessly with the RMS-TSG-TZ-C static trip unit.
Environmental Durability
This analog combination module operates reliably from 0°C to +60°C. It also withstands 95% relative humidity without condensation. The module survives vibration up to 2g from 10 to 150 Hz. Therefore, the GE IC694ALG442 suits most industrial control cabinets perfectly.
