ABB 1SAP170700R0001: High-Speed Communication for AC500 Systems

The ABB 1SAP170700R0001 enables robust serial communication in industrial networks. You can install this module into any AC500 or AC500-eCo PLC rack. It connects field devices using the RS-485 standard with Modbus RTU protocol. This interface suits distributed I/O, drives, and instrumentation applications.

Technical Specifications and Hardware Configuration

This communication module measures 112 mm in height. Its width reaches 35 mm, and the depth equals 76 mm. The ABB 1SAP170700R0001 weighs approximately 0.11 kilograms. A single internal PCB contains all isolation and driver circuits. The module uses one 5-pin screw terminal block for network wiring. It stores no energy in capacitors or internal batteries. Instead, it draws operational power from the backplane directly. Two rotary switches set the Modbus slave address from 1 to 247.

Communication Performance and Electrical Isolation

The ABB 1SAP170700R0001 supports baud rates from 9.6 kbit/s to 115.2 kbit/s. This module handles up to 32 slave devices on a single network segment. It provides complete galvanic isolation between the bus and logic side. The isolation voltage rating reaches 500 V AC for one minute. Consequently, this module eliminates ground loop problems in large installations. You can configure parity as none, even, or odd easily.

Installation and Diagnostic Features

You must snap this module onto a standard DIN rail next to the CPU. Transitioning to wiring, use shielded twisted-pair cables for best noise immunity. The module includes termination jumpers for end-of-line network configuration. Three front LEDs show power, data activity, and error status. A built-in watchdog resets communication after 100 ms of inactivity. The operating temperature range spans from -20°C to +60°C.
