GE 173C8413BDG02
The GE 173C8413BDG02 is a 4-channel analog input module for the GE Mark VI / Mark VIe distributed control system (DCS). It receives standard 4-20 mA or 0-10 V signals with independent galvanic isolation per channel, used for acquiring process variables such as temperature, pressure, flow, and level.
Technical Specifications
- Channels: 4
Detailed content
- Input Signal: 4-20 mA two-wire / 0-10 V (configurable)
- A/D Resolution: 16-bit
- Accuracy: ±0.1% full scale
- Inter-channel Isolation: 1500 VDC continuous
- CMRR: ≥ 120 dB at 50/60 Hz
- Input Impedance: 250 Ω (current mode), 1 MΩ (voltage mode)
- Sampling Rate: 250 ms/channel typical
- Power: 5 VDC and 24 VDC from Mark VI rack backplane
- Power Consumption: ≤ 2 W per module typical
- Operating Temperature: 0°C to 60°C
Functional Features
- Four fully isolated channels with no inter-channel interference
- Open-wire detection; automatically flags faults on input loop break
- Sensor fault detection (HART-capable variants supported)
- Front-panel LED status indicators
- Hot-standby redundancy support
- Online insertion/removal without affecting other channels
Structural Characteristics
- Standard Mark VI I/O module form factor
- Plug-in installation with hot-swap support
- Front-panel programmable jumpers and LED indicators
- Rear backplane: Mark VI standard high-speed serial bus interface
- Bottom signal terminal strip
Installation Requirements
- Install in a standard Mark VI I/O rack
- Use shielded twisted-pair signal cables with shield single-point grounded at the control room end
- Rack ground resistance ≤ 4 Ω
- Ambient temperature 0°C to 60°C, relative humidity 5% to 95% non-condensing
Usage Precautions
- In current mode, never connect signal lines in parallel
- In voltage mode, the 1 MΩ input impedance requires verification of signal source drive capability
- In redundancy configuration, the two modules must be addressed as a redundant pair
- Confirm rack power is stable before energizing the module
Target Industries
Thermal power, petrochemical, natural gas processing, water treatment, and pharmaceutical manufacturing.
