IP Relay HWg-ER02b
Ethernet relay, DIN rail, Web interface.
The Ethernet relay features 2x DI (dry contact input), a full RS-232/485 serial port, and 2x DO (relay
output, 230V/16A). It is controlled over the web or Modbus/TCP.
Relay outputs can directly switch 230V/16A AC mains, dry
contact inputs can be used e.g. for buttons. The device
features a full RS-232/485 serial port for connecting
e.g. a RFID or barcode reader. Industrial model, fits
on a DIN rail.
Two devices can be connected against each
other (Box-2-Box mode) to extend the digital
and RS232 signals over a computer network.
