Digital I/O Boards - 24 Bit and 64 Bit

 

The H1750M and H1770M boards are 24 bit and 64 bit of digital inputs and outputs. The status of inputs and outputs is communicated to the host in either Modbus RTU or DGH ASCII format using RS-232 or RS-485 serial communications. The input or output direction of each digital bit may be set individually or all at once. 

 

All user selectable options (address, baud rate, etc.) are done through the communications port and are stored in nonvolatile EEPROM memory.

 
H1750M

The H1750M series board level digital I/O products provide direct interface to industry standard mounting racks and I/O modules. Mounting racks such as the WRC4-A16H and WRC4-A24H can be controlled directly with the H1750M boards.

The status of up to 24 digital inputs and control outputs are communicated to any host serial port in Modbus RTU or DGH ASCII using jumper-selectable RS-232 or RS-485.

The H1750M series allows the user to specify the direction of each I/O line as either an input or an output bit. Bit addresses may be specified in two different formats, using either hexadecimal or decimal numbers. The I/O assignments are saved in EEPROM so that all pin directions are automatically configured when the device is powered up. Assigning the data direction of each I/O line may be specified individually or all at once using simple commands from the H1750M command set.

Two versions are available. The H1750M-1 shown to the right contains a female 50-pin ribbon connector mounted on the bottom of the PC board. The H1750M-2 contains a male 50-pin ribbon connector mounted on the top of the PC board.

The H1770M series board level digital I/O products provide direct interface to industry standard mounting racks and I/O modules. Mounting racks such as the WRC4-A16H can be controlled directly with the H1770M boards.

The status of up to 64 digital inputs and control outputs are communicated to any host serial port in Modbus RTU or DGH ASCII using jumper-selectable RS-232 or RS-485.
