You are correct the GPIO4D replaces the relay's that drive the contactors not the contactors themselves.

You can find the output relay spec's in the GPIO4D manual I posted earlier in this thread.

Question: Can the MPU11/GPIO4D Mach kit run third party drives in velocity as well as torque mode?

Answer: Yes you can run in velocity or torque mode with either the Mach3 software or the CNC11 software. Velocity mode allows for smoother motion with lower resolution encoders.

Question: Do I need to use the existing deceleration switch for the z-axis on my Bridgeport Series II mill? Answer: No you do not need to use the decel. switch because the machine only moves at the slow jog rate during homing. Which by default is 24 ipm. Once the machine is homed the Z-axis cannot g...

You can wire your probe into DP4 input (IN 14) on the DC3IOB and create a brain in Mach3 software to verify the probe is hooked up right. Use modbus input 14, with bit only checked. This will allow you to see input 14 change when you toggle the probe. Then to do probing or digitizing you will need t...

Adding probing to Mach3 software is something we are looking into, but I don't have a time frame of when it will be added. If you are looking at do probing you can purchase the Centroid software and a DP4 probe and start probing right away.

I have attached the GPIO4D manual to this posting. Please download and read it over, it should answer all your questions. All the outputs are SPST except OUT 8 and 9 which are SPDT. Yes the GPIO4D will replace your existing contactors, however you will want to add fuses after the output relays for p...
