REMOTE ACCES 24-bit Digital I/O Card
Model RDG-24 is an intelligent, 24-bit parallel digital-I/O-to-compu
ter interface unit. RDG-24 is enclosed in a steel enclosure for use in hostile environments. There are no switches or jumpers to set to enable half-duplex operation. In RDG-24 there are jumpers to bypass the opto-isolators if you wish, plus there are jumpers to set full-duplex operation if you desire.
Features
Remote Intelligent Digital I/O
Opto-Isolated RS-485 Serial Interface to Host Computer
24-Bit Digital I/O Programmable Bit-by-Bit, in 8-Bit Bytes, or in 24-Bit Words
Digital Input and Output Voltages up to 50VDC
Open Collector Digital Outputs for Loads up to 350mA
Protective Steel Enclosure
Type 8031 Microcontroller with 8K x 8 RAM and 8K x 8 EEPROM (32K x 8 optional)
All Programming in Software, No Switches to Set. Jumper to Set 2-Wire or 4-Wire modes, and Jumpers (3) to By-Pass Opto-Isolators if Desired.
16-Bit Digital-Input Software Counters
Change of State Flag Readable via the Serial Port
Digital Outputs May Be Either Level or Pulse.
