FAQ

This module is primarily designed for use with Schneider Electric's Modicon M340 and Modicon Premium PLC series. It connects to 16-channel discrete I/O cards via a HE10 connector cable.

No, the electromechanical relays on the ABE7-H16R21 are soldered directly onto the PCB and are not designed to be individually plugged in or replaced. The entire sub-base must be replaced if a relay fails.

The maximum current per channel is 0.5A at 30V DC. However, the total current for the entire module (sum of all channels) should not exceed 1.6A to avoid overloading the common power supply path.
