Description
GE IC610MDL116A Technical Specifications:
- Number of Channels: 16 (2 groups of 8)
- Input Voltage: 24V DC (18V–30V range)
- Input Type: Sink (NPN) — common per group of 8
- Isolation: 500V DC channel-to-logic, 500V DC group-to-group
- Response Time: 10ms (on), 10ms (off)
- Filter: 5ms (fixed)
- Current per Channel: 5mA
- Power Consumption: 500mA from bus
- Operating Temperature: 0°C to 60°C
Functional Features:
- Per-channel green LED shows input state
- Group fault LED shows if any input in a group has failed
- Conformal-coated for harsh environments
- Locking terminal blocks prevent accidental disconnection
Application Scenarios:
- Power Plants: Turbine valve position, boiler feed pump status, condenser level switches
- Water Treatment: Filter backwash status, chemical dosing valve feedback
- Mining: Conveyor belt rip switch, emergency stop buttons, gate position sensors
Material Composition:
- PCB: Multi-layer FR-4, conformal coated
- Terminals: Locking screw terminals, nickel-plated
- Optocouplers: Industrial-grade, per-channel
- Housing: Metal front bezel, plastic rear
Working Principle: Identical in principle to the IC200MDL240B but with slower 10ms response time and fixed 5ms filter. The 24V DC input drives an optocoupler LED, which switches a phototransistor on the logic side. The CPU reads the state of each phototransistor during its scan cycle. Installation Requirements:
- Install in Series 90-70 chassis (IC610CHS001 or equivalent)
- Wire 24V DC field devices to terminal block
- Connect common return (COM) for each group to the negative of the 24V supply
- Use shielded cable for runs over 30m
Usage Notes:
- This is a legacy module — newer installations should use IC200MDL240B for better performance
- The 10ms response time is too slow for high-speed counting applications
- The fixed 5ms filter cannot be disabled — account for this in your logic timing
