ATI: SC29 Master Module Assembly 9121-SC29-M
The module is designed to provide control of the Tool Changer, pass electrical power and signal connections to a servo motor, and pass Ethernet field bus data to the end‑of‑arm tooling. Power and signal circuits are electrically isolated both from each other and the Tool Changer. The wiring has EMI/RF shielding to protect it from noise. Compliant spring probes are provided on the Master and fixed contact pins on the Tool (refer to Figure 1.1). When the Tool Changer is coupled, the Master and Tool modules transfer signals and power across the spring probes and contact pins. A V‑ring seal surrounds the pin blocks to seal the connections from moisture and liquid while coupled
The modules are equipped with tool stand interlock (TSI), a safety feature that uses a physical break in the unlatch solenoid valve circuit to prevent an unintended tool release. The TSI circuit allows Tool Changer release ONLY when the Tool is in the stand or storage location. Refer to Section 2.1—Tool Side TSI for additional information regarding TSI.
