Product Description

SNAT632PAC (ABB PN 61049428) is a plug-in pulse-amplifier and serial-communication board designed for Advant/Safoc DC-drive converters and early ACS/DCF inverter families. This board amplifies fast encoder or tachometer pulses up to 200 kHz and provides isolated RS-485/RS-422 communication links, eliminating external interface hardware and reducing cabinet wiring by over 30%.

Key Features & Benefits

High-speed pulse input - differential line-driver, 200 kHz maximum frequency, 5V or 24V selectable
Isolated outputs - 6 x 24V push-pull channels, 0.5A peak current, short-circuit protected
On-board serial port - isolated RS-485/RS-422 interface, 115.2 kbaud, Modbus-RTU slave protocol
Plug-and-play installation - DIN-rail mounting, 24VDC power supply, LED diagnostic indicators
Wide temperature range - 0°C to +70°C operating, -40°C to +85°C storage
Global certifications - CE, UL 508, RoHS, REACH compliant
