EXSYS EX-47900IS RS-232 – RS-422/RS-485 sarjamuunnin 2,5kV eristyksellä

Convert RS-232 signals to RS-422 or RS-485 with 2.5kV optical isolation, 15kV ESD protection, and 600W surge protection for reliable industrial communication.

Overview

The EXSYS EX-47900IS is a hardware-based serial converter that bridges RS-232 to RS-422 or RS-485 interfaces. It supports both 2-wire half-duplex and 4-wire full-duplex RS-485 modes, as well as RS-422 full-duplex. Automatic Data Direction Control (ADDC) eliminates the need for software handshaking.

What stands out

• 2.5kV optical isolation protects against ground loops and voltage spikes.
• 15kV ESD and 600W surge protection ensure robust operation.
• Supports data rates up to 115.2 Kbps and distances up to 1.2 km.
• DB9 female RS-232 connector and 5-pin terminal block for RS-422/485.
• LED indicators for power, transmit, and receive status.
• SECC metal housing with wall mount option; DIN-rail kit available separately.
