If the corresponding channel LED illuminates but the field actuator remains unenergized, use a multimeter to measure the 24 VDC voltage output directly at the terminal strip connector. If voltage is present at the module terminal, the issue resides in the field wiring or the actuator coil itself; if no voltage is present, the internal driving transistor for that specific point may be damaged.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the primary precautions when connecting highly inductive loads like large relay coils to this module?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach channel is strictly rated for 0.5 A. When driving inductive loads, the collapsing magnetic field can produce a reverse high-voltage transient (inductive kickback) capable of punching through the output transistors.
