Digital-to-Analog Conversion
The digital-to-analog (D/A) circuitry features two 12-bit converter channels in each AD7237 D/A converter IC for a total of eight output channels. The two channels in each AD7237 are internally double buffered and all channels are simultaneously updated by issuing a single command. Each channel can be jumpered to one of four output voltage ranges, ±5, ±10, 0..+5, or 0..+10 Volts.
Digital I/O
The DM5604 has 24 TTL/CMOS-compatible digital I/O lines which can be directly interfaced with external devices or signals to sense switch closures, trigger digital events, or activate solid-state relays. These lines are provided by the on-board 8255 programmable peripheral interface chip. The 8255 can be operated in one of three modes. Pads for installing and activating pull-up or pull-down resistors are included on the module. Installation procedures are given at the end of Chapter 1, Module Settings.
