I-7522A Addressable RS-485 to RS-232/422/485 Converter with 5 DI/5 DO
Addressable RS-485 to multi-port serial converter with 5 digital inputs and 5 open-collector outputs, giving RS-232 devices a unique address on an RS-485 network.
- Addressable RS-485 to RS-232 converter firmware assigns a unique address to RS-232 devices on an RS-485 network
- Master-type design operates without a host PC dependency, unlike slave-type converters
- Three COM ports: 1 x RS-422/RS-485, 1 x RS-485 and 1 x RS-232/RS-485, up to 115200 bps
- 5 dry-contact digital inputs (non-isolated) and 5 open-collector digital outputs rated 100 mA at +30 VDC
- Power-up and safe values for digital outputs, plus dual-watchdog command support
- 1 KB queue buffer for each RS-232 interface

Produktinformation "I-7522A Addressable RS-485 to RS-232/422/485 Converter with 5 DI/5 DO"
The I-7522A CR lets standard RS-232 devices sit on an RS-485 bus with their own device address. The unit strips the address from incoming commands, passes them to the local serial device and returns the response to the host, so legacy serial equipment can be integrated into an addressed multi-drop network without changing the device itself.
Unlike slave-type converters that depend on a host PC for every transaction, this master-type converter can be configured to work independently. It adds five dry-contact digital inputs and five open-collector digital outputs, with support for power-up and safe output values, dual-watchdog commands and real-time monitoring and control of the on-board I/O. Each RS-232 interface includes a 1 KB queue buffer.
The module is built around an 80188-compatible CPU at 40 MHz with 512 KB flash and 512 KB SRAM. It accepts a +10 to +30 VDC supply with reverse polarity protection, draws 2.0 W, and is designed for DIN-rail or wall mounting over an operating range of -25 to +75 °C.
Applications
- Integrating RS-232 instruments and controllers into an RS-485 addressed network
- Adding local digital I/O to remote serial networks
- Standalone control of local outputs with watchdog-based fail-safe behaviour
- Converting between RS-232, RS-422 and RS-485 serial links in industrial control systems
