Input Isolation Features
Each of the 16 channels features a separate opto-isolator for complete electrical separation. The GE DS3800HIOA1C1E accepts input voltages from 5V to 24V DC. Consequently, you can connect various sensor types without level conversion. The isolation voltage reaches 4000V RMS between any two channels. Thus, a surge on one input will not affect the remaining fifteen channels.
Signal Conditioning Performance
The onboard conditioning IC filters and shapes each incoming signal. This IC removes contact bounce and electrical noise effectively. The response time reaches just 50 microseconds for clean switching. Therefore, the GE DS3800HIOA1C1E captures high-speed digital events accurately. The input threshold current sits at 2.5 mA for reliable detection.
Power and Energy Storage
The GE DS3800HIOA1C1E draws only 80 mA from a 5V DC supply. Hence, its total power consumption equals just 0.4W. The two 47µF ceramic capacitors provide 8 milliseconds of hold-up time. This short backup protects input states during minor voltage sags. Furthermore, the board generates virtually no heat during operation.
Installation and Connectivity
You can mount the GE DS3800HIOA1C1E on a standard DIN rail. Alternatively, use M3 screws for direct panel mounting. The 34-pin header connects to the host controller via a ribbon cable. The 20-pin terminal block accepts wire sizes from 0.14 mm² to 1.5 mm². For best performance, route input wires away from power cables. The GE DS3800HIOA1C1E works seamlessly with the RMS-TSG-TZ-C static trip unit.
Environmental Durability
This input isolator board operates reliably from -20°C to +70°C. It also withstands 95% relative humidity without condensation. The board survives vibration up to 2g from 10 to 500 Hz. Therefore, the GE DS3800HIOA1C1E suits harsh industrial environments perfectly.
