Schneider Electric ACE919CC Interface Network Module

The Schneider Electric ACE919CC Interface Network Module is a DC-powered RS-485/RS-485 converter that bridges a master RS-485 port to a two-wire Sepam network and is designed for DIN-rail mounting. The ACE919CC accepts a 24 to 48 V DC input and provides a distributed power supply for Sepam interfaces (such as ACE949-2, ACE959, or ACE969-2) at up to 250 mA per interface, supporting up to 12 interfaces in a system. It features galvanic isolation of 2000 Vrms between the power frame and the interface supply, a female 9-pin Sub-D RS-485 connector, an 11-bit data format (1 start, 8 data, 1 parity, 1 stop) with a transmission delay under 100 ns, and is compatible with symmetrical or asymmetrical DIN rails. Additional specs include a compact 0.28 kg weight, a 5 mm x 20 mm time-delayed fuse (1 A), and an operating range from -5°C to 55°C.
