Product Description

AT1616L  - RS485 / RS232 Microprocessor Based Remote Digital I/O Board with on board WAGO terminal strips.

This board is used worldwide for gathering digital input data and controlling external devices through the 16 isolated inputs and the 16 form C independent relays. In addition to the commands for reading and writing the I/O points, there are a set of commands, which enable the user to check the I/O status, unit type, unit address, configuration, software version, and jumper settings.
The new command structure maximizes the data flow to and from the board. The classic command structure has been preserved to maintain compatibility with our earlier installed base of units. The choice of command structures is selected by a single jumper, J19. When the configuration jumpers are changed, the power to the board must be cycled to make the changes effective.

  • This unit interfaces 16 opto-isolated inputs and 16 form C relay outputs to a host computer through a bi-directional serial port at jumper selectable data rates up to 115.2 Kbps.

  • The addressable bi-directional RS485(2 wire) port provides multi-drop capability at the device count and distance limitations of the RS485 EIA/TIA specification. Typically: 32 standard loads at 4000 ft.

  • The addressable bi-directional RS232 port provides point to point communications at the distance limitations of the RS232 EIA/TIA specification.

  • The 16 opto-isolated inputs can be jumper configured to be driven by contact closure with a common connection and the excitation voltage provided by the board.

  • The 16 opto-isolated inputs can also be jumper configured as floating inputs driven by an external signal of 5 to 27 VDC at 1.2 to 9 mA.

  • The 16 form C relay contacts are rated at 1 amp at 30VDC.

  • The onboard firmware accomodates a wide variety of operational modes. A new, compact, fast command structure enhances the user interface. The classic command structure has been preserved for compatibility with older systems.

  • The extensive flexible command structure is fully explained on the RS485.com web site

  • When factory configured in "Stand Alone" mode, two units serve as a I/O extension pair through a serial link. The inputs on one board energize the corresponding relays on the other board

  • LEDs provide visual indication of input , output, data activity, and power level.

  • A polarity protected efficient switching power regulator accepts supply voltages from 9 to 35 VDC (2 Watts max.)

  • User connections are spring loaded "Wago" style terminal strips for I/O, the RS485 interface, and supply power. An RJ11/12 telephone style connector is used for the RS232 interface.

  • Broad environmental range. Temperature: -40C to +85C (-40F to +185F). Humidity: 10 to 90% RH (non-condensing)

  • Six(6) easy mount through hole standoffs, which accept #6 hardware, are provided on the circuit board.

  • Accessories available are a 12VDC Switching Power Supply (Wall Wart), and a 7ft DB9F to RJ11/12 RS232 cable.

  • We strongly recommend that a first time user of this product purchase the optional DB9F to RJ11/12 RS232 cable.

  • The limitations of the RS232 communications method can be solved by the wide variety of R E Smith devices. Our converters, buffers, isolated converters, and addressable converters mitigate the distance limitations and electrical noise problems that contribute to unreliable communications and product failure.

  • Conformal Coating, other cables, and other connectors are factory options. If what you see here is not exactly what you need, don't hesitate in calling us at (513) 874-4796
