24-Bit Digital I/O Pod
RIOD24
Remote ACCES Distributed I/O Pods provide intelligent sensor interfaces via two-wire RS-485 multidrop networks to host PCs. Model RIOD24 is ACCES' answer to Distributed Digital I/O needs. With these Pods you can connect 2 wires to any computer and be quickly controlling and acquiring your digital signals. RS-485 supports very long cable lengths (up to 4000 feet) and with our Wireless option you can achieve over 10 miles between devices. The RIOD24 comes standard in a NEMA4 enclosure provided excellent protection from the elements, indoors or out. The closable gasket aperture forms a perfect seal around your round cable, and our conductive lid-gasket and solid aluminum box prevent EMI emmisions for those noisy factory floor environments. Digital Inputs may be read individually, in 8-bit bytes, or in 24-bit words at voltages up to 50 VDC. There are also digital software counters on each input. Selectable edges can be counted for up to 65,535 transitions. These counters support Read and Reset commands. Moreover, change-of-state flags can be set on any enabled input bits and can be read via the serial port. This is particularly useful in applications where it is necessary to detect contact closures or openings. This change-of-state detection capability is enabled on a bit-by-bit basis for all bits that are programmed to be inputs. Digital-input sample rate is software programmable from 14 Hz to 1 KHz. Digital Outputs may be programmed individually, in 8-bit bytes, or in 24-bit words. These outputs may be latched, pulsed, or set to free run at a programmed rate. The digital output drivers are open-collector circuits that have 350 mA drive capability at a logic "low". RIOD24 outputs can comply with up to 50 VDC (voltage supplied by you) or, if no external voltage is available, outputs will be pulled up by an internal 10 kilohm resistor to 5 VDC. The digital-output square wave pulse rate is software programmable from 7 Hz to 500 Hz. A built-in watchdog timer resets the pod if for some unexpected reason the microcontroller "hangs up" or if the power supply voltage drops below 4.75 VDC. Also, data collected by the pod are stored in local RAM for later access through the computer's serial port. This feature facilitates a stand-alone mode of operation. For example, a notebook computer can connect to the RS-485 network and collect the data.
