Expert Review

• Field Engineer’s Insight: This 48-pin connector provides reliable screw termination for S7-400 analog I/O. The reference temperature detection helps with thermocouple cold-junction compensation. Use this connector when replacing damaged wiring or building new panels. Always torque screws to 0.5-0.6 Nm to prevent loose connections. The connector ships as part of the analog module package but buying spares saves downtime.
