EtherStax I/O blocks provide a ruggedized, high-density solution to interface a very large quantity of discrete I/O signals to your control system. A stackable aluminum housing maintains a small footprint and stands up to harsh, industrial environments. Web-based configuration simplifies setup with any web browser.
Performance Specifications
Inputs
Configuration (active-low inputs): 96 channels (six 16-ch ports) with a common return (RTN). Each input is connected in tandem with open-drains of output mosfets. Any mix of I/O occurs as all channels are high impedance inputs unless written. Output channels can be read back at any time (loopback monitoring). Input Signal Voltage Range: 0 to 28VDC, 31V maximum. Surge protected. Input Threshold Detection and Sensitivity: 4V DC threshold. Level or latching inputs. Input “Wetting” Current: Built-in current sources switch from 16mA initially (20ms) to 2mA (continuous), default mode. Sources can be changed to 2mA or turned off. Internal Excitation (default): 6V DC, 400mA External Excitation: 6 to 28V DC typical. Separate excitation terminal (logic) for each 16-channel port. Internal and external supplies are diode-blocked from each other. Includes reverse polarity protection. Peer-to-peer (i2o) communication: Change-of-state updates: Less than 5mS events. Timed updates: Configurable for 1-90 seconds.Outputs
Configuration (low-side switches): 96 channels (six 16-ch ports) of open-drain mosfet switches with common source connection at port RTN terminal. Each output is connected in tandem with buffered inputs. Output “OFF” Voltage Range: 0 to 28V DC, 31V maximum. Surge protected. Output “ON” Current Range: 0 to 300mA DC continuous, each output. Output “ON” Maximum Current: 450mA DC maximum with any 8 channels “on” continuously per 16 channel port Output Port Maximum Current: 4.8A: 16 channels @ 300mA continuous. 3.6A: 8 channels “off” & 8 channels @ 450mALocal Alarm Output
