The IC670MDL740 belongs to the GE Fanuc Field Control series. This module provides 16 discrete output channels in a single group. It uses positive logic and sourcing-type outputs. Each output supplies current to the load by switching to the positive side of the DC power supply. The nominal voltage is 24 VDC, while the user input voltage ranges from 10 to 30 Volts DC. The output voltage spans 9.2 to 29.5 VDC.
For load control, each point handles 0.5 Amps continuously. The entire module supports a maximum of 4 Amps total. Moreover, the IC670MDL740 works well with pilot lamps, relay coils, and solenoid actuated devices. These devices typically require low current ratings. The output response time is 200 ms at 0.5 A resistive load. Additionally, the output voltage drop stays below 0.5 Volts maximum.

The IC670MDL740 includes a built-in 5 Amp slow-blow fuse. This fuse connects to the external power supply. It serves two important purposes. First, it protects the module against excessive current flowing through the output points. Second, it guards against polarity errors in the external power supply. If you connect the power supply incorrectly, the fuse blows immediately.
Furthermore, the module sends blown fuse diagnostic messages to the bus interface unit. A dedicated LED indicator shows the fuse blown status. The module also detects when the user supply voltage drops below 9.8 Volts DC. Therefore, you receive clear warnings before performance degrades. For replacement, use a slow-blow type fuse rated at 5 Amps and 250 Volts AC.
Three types of LEDs help you monitor the IC670MDL740. First, individual status LEDs show the on/off status for each of the 16 output channels. Second, a fuse blown LED lights up when the internal fuse fails. Third, a power status LED indicates if the user supply voltage is present. Consequently, you can diagnose most issues without opening the cabinet.
The IC670MDL740 comes with an integrated 25-terminal block. Each terminal accepts a single AWG #14 to AWG #22 wire. You can also terminate two wires using AWG #18 wire. If you install an external jumper, the permitted wire size reduces to AWG #14 to AWG #16. Always use proper wire gauges to prevent overheating. Tighten connections securely to avoid intermittent operation.
First, mount the bus interface unit on a DIN rail or panel. Next, attach the IC670MDL740 to the Field Control base. Then, connect an external 24 VDC power supply to the module. Pay close attention to polarity. A reversed connection blows the fuse immediately. After that, wire your field loads to the terminal block. Connect each load between an output terminal and the common return.
For positive logic, the output turns on when the logic signal is high. Meanwhile, verify that your load current does not exceed 0.5 Amps per point. Also, keep the total module current below 4 Amps. Finally, test each output with a small load first. This confirms correct wiring before full operation.

1. What happens if I exceed 0.5 Amps on one output of the IC670MDL740?
The built-in 5 Amp fuse protects the entire group. However, exceeding 0.5 Amps per point may damage the output transistor. Always stay within the rated limit.
2. Can I use the IC670MDL740 with AC loads?
No. This module works only with DC loads from 10 to 30 Volts DC. For AC loads, select a different output module.
3. How do I know if the fuse has blown on the IC670MDL740?
The module has a dedicated fuse blown LED. Additionally, the bus interface unit receives a diagnostic message. Replace the fuse with a 5 Amp slow-blow type rated at 250 VAC.
4. Does the IC670MDL740 provide isolation between outputs?
No. All 16 outputs share a single group. There is no group-to-group isolation. Use external isolation if your application requires it.
5. What is the minimum load current for each output?
The minimum load current is 1 mA per point. Below this value, the output may not switch reliably. Add a parallel resistor if your load draws less than 1 mA.
