ماژول مبدل RS422 به TTL سریال MAX490

ماژول مبدل RS422 به TTL سریال MAX490

Features:
( 1) RS422 interface, two-way communication. ABYZ super long transmission 1000 meters
( 2) modules have 15KV of ESD protection.
( 3) Add 10 ohm current limiting overcurrent protection resistor on the board .
( 4) The module has a TVS diode. Anti-lightning, anti-spike voltage.
( 5) The module has a 120 ohm terminating resistor, which can effectively reduce long-distance communication echo interference.
( 6) There are power indicator lights and data transceiver indicators. The state of the data is unobstructed.
( 7) The TTL side of the module uses a 5v DC power supply RXD TXD compatible with 5V logic signals.
( 9) The module adopts imported MAX490 chip, the stability and communication speed far exceed domestic products, up to 2.5MBPS.
( 10) Module size: 5.0cm*2.7cm
