Siemens 6ES7292-1AG20-0AA0 Terminal Block

This terminal block serves as a spare connector for SIMATIC S7-200 I/O modules. The Siemens 6ES7292-1AG20-0AA0 connects field wiring to the PLC’s discrete and analog channels. It provides a reliable interface between sensors, actuators, and the controller. The unit ensures secure wire retention through its screw-type clamping mechanism. Its detachable design simplifies module replacement without disturbing field wiring.

Mechanical Dimensions and Construction Quality

The terminal block measures 45 mm in height, 28 mm in width, and 20 mm in depth. This compact size makes it ideal for space-constrained control cabinets. Weighing only 0.06 kg, the 6ES7292-1AG20-0AA0 adds minimal weight to connected cables. A durable polyamide housing offers excellent resistance to shock and vibration. This material also provides good insulation properties for safe electrical connections.

Interface and Connectivity Features

Twenty screw terminals accept solid or stranded wires from 0.5 to 2.5 mm². Each terminal includes a captive screw for secure and reliable connections. The terminal block provides two rows of terminals with ten positions each. Row numbers printed on the housing simplify wire identification and troubleshooting. The connector mates directly with S7-200 I/O modules via a polarised header.

Power and Electrical Specifications

The 6ES7292-1AG20-0AA0 handles rated currents of 10 A per terminal safely. It supports voltages up to 230 VAC or 24 VDC for standard industrial signals. The contact resistance remains below 10 mΩ for consistent electrical performance. The polyamide housing provides dielectric strength exceeding 2.5 kV. This rating ensures adequate insulation for most industrial applications.

Internal Construction and Component Details

Each terminal contains a screw clamp mechanism with a square washer for even pressure distribution. The brass contacts feature a tin plating for good conductivity and corrosion resistance. The housing includes polarising keys to prevent incorrect insertion onto the module. Two mounting flanges keep the block securely attached to the PLC module. The manufacturing process uses precision moulding for consistent connector alignment.

Environmental Performance and Certifications

This terminal block operates reliably from -40 °C to +100 °C in harsh industrial settings. It also withstands humidity levels from 5% to 95% without performance degradation. The 6ES7292-1AG20-0AA0 complies with UL 1059, CSA, and IEC 60947 standards. These certifications ensure safe use in global automation installations.
