15-Bit Modbus Digital I/O Modules

D1711M - 15 I/O Bits   D1712M - 15 I/O Bits Specifications   Product Photos

 

 
The D1711M Digital I/O module contains 15 user-selectable input/output bits. The bits can be individually programmed as digital inputs or digital outputs. A user-programmable Initial value can be assigned to each digital output bit, to turn "on" or "off" on power-up.

The modules contain a communications "watchdog" timer that can move the digital outputs to a safe-condition in the event of an RS-232 communications link failure.   

The modules contain an Events counter that can be used to count positive transitions, from logic "0" to a logic "1", on the B00 terminal. The module can count pulses up to 10 million.

D1701M - 7 Inputs, 8 Outputs D1702M - 7 Inputs, 8 Outputs Specifications Product Photos

 
 
 
The D1701M Digital I/O module contains seven digital input and eight digital output bits.

The digital input bits contain internal "pull-up" resistors. Therefore, a simple set of contacts can be applied between a digital input bit and ground.

The modules contain an Events counter that can be used to count positive transitions, from logic "0" to a logic "1", on the EV input terminal. The module can count pulses up to 10 million.

The D1701M contains an RS-232 serial output.
The D1702M Digital I/O module contains seven digital input and eight digital output bits.

The digital input bits contain internal "pull-up" resistors. Therefore, a simple set of contacts can be applied between a digital input bit and ground.

The modules contain an Events counter that can be used to count positive transitions, from logic "0" to a logic "1", on the EV input terminal. The module can count pulses up to 10 million.
