Wireless 8-channel Isolated Digital Input and 8-channel Isolated Digital Output Module. Supports DCON and Modbus RTU Protocols

  Price:  $349.00  


ZT-2055 applicationThe ZT-2055 offers 8 isolated channels for digital input and 8 isolated channels for digital output. Either sink-type or source-type digital input can be selected via wire connections. All digital input channels are also able to be used as 16-bit counters. The ZT-2055 supports source-type output with short circuit protection. There are options to enable both power-on and safe values. The ZT-2055 has 16 LED indicators to display the channel status, and has 4 kV ESD protection and 2500 VDC intra-module isolation. Users can easily configure the module address, protocol, checksum, ZB-PID and ZB-channel settings using a combination of rotary and DIP switches.
