Schneider 170PNT16020 | Modbus Plus Adapter

The Schneider 170PNT16020 provides high-speed network connectivity for Momentum I/O devices. This communication adapter supports the Modbus Plus protocol for peer-to-peer industrial networking. It connects Momentum I/O drops to a Modbus Plus network backbone. Weighing only 0.32 kg, the Schneider 170PNT16020 mounts directly onto Momentum I/O bases. Its dimensions measure 125 mm x 90 mm x 55 mm.

Communication Specifications and Network Capabilities

The Schneider 170PNT16020 delivers 1 Mbit/s transmission rates for reliable data exchange. This adapter supports up to 64 nodes on a single Modbus Plus network segment. It handles global data broadcasts for efficient peer-to-peer communication. Moreover, the Schneider 170PNT16020 includes built-in termination resistors for simplified network setup. Consequently, you do not need external terminators for proper network operation.

Diagnostic Features and Energy Storage

The Schneider 170PNT16020 features LED indicators for network status, communication activity, and module health. This adapter contains no internal battery for complete maintenance-free operation. The Schneider 170PNT16020 draws 250 mA from the 5 V DC backplane power supply. It also consumes 50 mA from the external 24 V DC field power supply. Therefore, you never need to replace batteries or worry about configuration loss.

Installation and Application Details

The Schneider 170PNT16020 snaps directly onto any Momentum I/O base. Align the adapter with the base connector and press firmly until secure. Set the node address using the rotary switches on the front panel. Configure the built-in termination resistor based on your network position. The Schneider 170PNT16020 requires external 24 V DC power for its communication circuits. Use Belden 9463 cable for all Modbus Plus network connections. This adapter suits distributed I/O applications, remote monitoring, and factory floor networking. Thus, the Schneider 170PNT16020 provides reliable Modbus Plus connectivity for Momentum systems.
